What is a digital camera

Digital camera (also known as: digital camera, English full name: Digital Camera, referred to as DC)

A digital camera is a camera that uses electronic sensors to convert optical images into electronic data. Different from the principle of ordinary cameras that rely on the chemical change of silver bromide to record images on film, the sensor of a digital camera is a light-inductive charge-coupled-{zh-cn: device; zh-tw: component}-(CCD ) or complementary metal oxide semiconductor (CMOS). Images are usually stored on a digital storage device (usually using flash memory; floppy disks and CD-RWs are rarely used in digital camera equipment) before being transferred to the computer.

[Edit this paragraph] Working principle

A digital camera is a product that integrates optics, mechanics, and electronics. It integrates components such as conversion, storage and transmission of image information, and has the characteristics of digital access mode, interactive processing with computers and real-time shooting. Light enters the camera through the lens or lens group, and is converted into digital signals through the imaging element. The digital signals are stored in the storage device through the image computing chip. The imaging element of a digital camera is CCD or COMS. The characteristic of this imaging element is that when light passes through, it can be converted into electronic signals according to the difference in light. Digital cameras first appeared in the United States. More than 20 years ago, the United States used them to transmit photos to the ground through satellites. Later, digital photography was converted to civilian use and its application scope continued to expand.

Advantages: 1. You can see the picture immediately after taking the photo, which provides the possibility to retake the unsatisfactory work immediately and reduces the occurrence of regrets.

2. Only pay for the photos you want to develop, and other unnecessary photos can be deleted.

3. Color reproduction and color range no longer depend on the quality of the film.

4. The sensitivity is no longer fixed by the film. The photoelectric conversion chip can provide a variety of sensitivity options.

Disadvantages: 1. Due to the conversion of imaging components and image processing chips, the imaging quality lacks a sense of hierarchy compared to optical cameras.

2. Due to the different image processing chip technologies of various manufacturers, the colors displayed in the imaging photos are different from the actual objects.

3. Due to the lack of core technology in China, the cost of later use and maintenance is high.

[Edit this paragraph] Brief history of development

1. Birth

The history of digital cameras can be traced back to the 1940s and 1950s. · Crosby Laboratory invented the video recorder (VTR), a new machine that could record electrical pulses from television broadcasts onto magnetic tape. By 1956, video recorders began to be mass-produced. It is considered to be produced by electronic imaging technology.

In the 1960s, NASA had to survey the lunar surface before astronauts were sent to the moon. However, engineers found that the analog signal sent back by the detector was mixed with other rays in the universe and appeared very weak. Receivers on the ground were unable to convert the signal into a clear image. So engineers had to find another way. 1970 was a landmark year in the image processing industry. Bell Laboratories in the United States invented the CCD. When engineers use computers to digitally process the image information obtained by the CCD, all interference information is eliminated. Later, a device using CCD was installed on the "Apollo" moon landing spacecraft, which was the prototype of a digital camera. During the Apollo missions to the moon, the digital images received by NASA were crystal clear.

After this, digital imaging technology developed faster, mainly due to technological competition during the Cold War. These technologies are also mainly used in the military field. Most spy satellites use digital imaging technology.

In the history of digital camera development, Sony must be mentioned. Sony first used CCD in a television camera in August 1981, using it as a sensor that directly converts light into digital signals. At present, the CCDs produced by Sony every year account for 50% of the global market. This is one of the reasons why Sony can dominate the digital camera market, because the core lifeline is in its own hands.

After the end of the Cold War, military technology quickly transformed into market technology. In 1995, Kodak, which produces traditional cameras and has strong film production capabilities, released its mature consumer digital camera DC40 to the market. This is regarded by many as the beginning of the formation of the digital camera market. DC40 uses a built-in 4MB memory and cannot use other removable storage media. Its 380,000-pixel CCD supports generating 756×504 images and is compatible with Windows 3.1 and DOS. Apple's QuickTake 100 was also launched on the market at the same time. At the time, both cameras provided a serial connection to a computer.

Since then, the pixels of digital camera CCDs have continued to increase, their functions have been continuously updated, and the image effects captured have become closer and closer to traditional cameras.

2. Development history

1. Digital cameras in the 1990s

(1) Early products As early as the 1960s, the "CCD Through the research and development of "chips", we have developed digital cameras for the aerospace industry and sent aerospace photos from space to the ground through satellite systems. In 1969, the United States landed on the moon for the first time to take pictures, and left a special 500EL Hassanbot digital camera on the moon for a long time.

In 1981, Sony invented the world's first electronic still camera that did not use photosensitive film - the still video "Mavica" camera. This was the prototype of today's digital camera.

In 1988, Fuji and Toshiba exhibited the jointly developed Pujixs (Fujix) digital still camera "DS-1P" using flash memory cards at the Cologne Expo. , Fuji, Toshiba, Olympus, Konica, Canon, etc. have successively released prototypes of digital cameras: such as Canon RC-701, Casio VS-101, Fuji DS-1P, Fuji DS-X, Toshiba MC2000, etc.

(2) Products in the early 1990s. In 1991, Kodak successfully trial-produced the world's first digital camera. Toshiba released the 400,000-pixel MC-200 digital camera, priced at 1.7 million yen. It was the first digital camera sold on the market.

In 1994, Kodak's commercial digital camera DC40 was officially launched. In February 1995, Casio released the QV-10, a low-priced digital camera with 250,000 pixels and a price of 65,000 yen, which triggered a boom in the digital camera market. In 1995, the Canon EOS·DCS3C was launched, and in the same year, the EOS·DCS1C was also launched, starting the history of the development of Canon digital SLR cameras. In 1995, the digitization of cameras officially kicked off. In order to welcome the arrival of digital cameras, the board of directors of Kodak made a decisive decision to comprehensively develop digital science in 1995. In 1996, it jointly launched the DCS-460 and DCS-620X digital cameras with Nikon, and the DCS-420 digital camera in cooperation with Canon. Camera (professional grade).

In 1995, the world's digital cameras had only 410,000 pixels; by 1996, the number had almost doubled to 810,000 pixels, and digital camera shipments reached 500,000 units; in 1997, it increased to 100. Megapixel, digital camera shipments exceeded 1 million units.

In 1996, Olympus and Canon also launched their own digital cameras. Subsequently, nearly 20 companies, including Fujifilm, Konica, Minolta, Nikon, Ricoh, Contex, Sony, Toshiba, JVC, and Sanyo, successively participated in the R&D and production of digital cameras, and each launched a digital camera.

In November 1997, Kodak released the DC210 zoom digital camera, which used a 1.09 million square pixel CCD image sensor; Fujifilm released the DC-300 digital camera.

In 1997, Olympus first launched the CA-MEDIAC-1400L SLR digital camera with "super million" pixels, which caused a huge shock in the industry.

One of the most striking features of the 1997 PMA International Photographic Equipment Expo in the United States was the combination of traditional photographic equipment and computer information processing, and the ingestion and transmission of images became the most common aspect between the optoelectronics industry and the computer industry. career, some IT manufacturers began to get involved in digital photography. Major companies are launching more popular digital cameras of less than 1,000 US dollars, with the cheapest being less than 200 US dollars, which creates conditions for digital cameras to enter ordinary people's homes.

The hot spot and mainstream product of popular digital cameras in 1997 was a digital camera with a CCD pixel count of about 350,000 and a maximum resolution of 640×480 pixels. "Megapixel" cameras have just "emerged", and only four companies, Fujifilm, Olympus, Kodak and Konica, have launched a new product each. The focus of the development of popular digital cameras, in addition to improving resolution, is to develop special functions, that is, some functions that traditional film cameras do not have and cannot achieve, to show the superiority of digital cameras, such as equipping the body with an LCD monitor screen. The viewfinder and the function of checking the shooting effect on the spot after shooting, the function of making the lens rotate a certain degree, the function of combining the LCD screen to facilitate selfies, the function of quickly transferring image data to the computer, etc.

(3) In 1998, Fujifilm launched the first million-level (1.5 million pixels) NEPIX700 digital camera, the lightest, smallest and most popular digital camera; Canon and Kodak cooperated to develop the first LCD camera Monitors for digital SLR cameras EOSD2000 and EOSD6000.

1998 was the year when low-priced "megapixel" digital cameras became a new hot spot and mainstream product. In that year, more than 60 new models were released or sold by more than 20 manufacturers: Casio (4 types), Fujifilm (8 types), Kodak (4 types), Minolta (3 types), Nikon (3 types), Canon (4 types), Olympus (4 types), Sanyo (6 types) ), Sony (6 types), Seiko Epson (4 types), those who released two types are "Acfa, HP, Konica, Nilipu, Ricoh; those who released one type are: Toshiba, Panasonic Electronics, Hitachi, JVC, Kyocera, Leica, Samsung and China's Seagull account for about 80% of all new models that reach and exceed "megapixel", including the Canon PowerShotPro70 digital camera with a maximum of 1.68 million pixels and a 2.5x optical zoom. And 2x digital zoom, TTL automatic focus, automatic exposure, 2-inch color TPY LCD screen, with a maximum continuous shooting function of 4 frames per second

In terms of functions, the digital camera in 1998 was. A lot of effort has been put into it, and they can be summarized as follows: 1. Optical zoom lenses are available, including 2x, 2.5x, 3x, 5x and 10x, and some cameras also have up to 14x. It has a digital zoom function of 2x or 4x.

Kodak DC260 digital camera: 1.6 million pixel CCD image sensor; 3x optical zoom and 2x digital zoom; can be connected to a flash sync cable; shutter priority. Aperture priority automatic exposure function, shooting program preset function; USB interface, etc.

2. Casio QV-7000SX digital camera: launched on the market in September 1998, it is the highest-end product in the OV series. x optical zoom and 4x digital zoom, aperture priority automatic exposure, 7 operating parameter customization functions. In addition, there are phase difference passive automatic focus or manual focus, multi-zone metering or spot metering, LCD display, image. 2x magnification, automatic date recording, HTML file generation and various shooting functions.

3. Minolta DemageEX series digital cameras: launched on the market in October 1998, including EXzoom1500 and EXwiea1500 models; the former is equipped with a 3x zoom lens-CCD unit (7-216mm/F3.5- 5.6), the latter is equipped with a large-aperture wide-angle lens - CCD unit (5.2mm/F1.9). Its unique feature is: using a 1/2-inch 1.5 million pixel primary color sequential scanning CCD3 equipped with a dedicated "Didta" It is a dedicated operating system for digital imaging with software scalability; it has a continuous shooting function of 3.5 frames per second and up to 7 frames; it can set 5 scenes; it has operational performance comparable to traditional film.

4. Minolta DemageRD3000 digital camera, this camera is based on the "APS" SLR camera S-1, an interchangeable lens SLR digital camera, using 2 CCD image sensors with a total of 2.7 million pixels.

5. The waterproof and dustproof "megapixel" camera debuted on the stage as the Fujifilm BigJobDS-25OHD digital camera. It is based on the Fujifilm FinePix700 CCD camera with a total pixel of 1.5 million and uses Japanese Industrial Standard Level 7 A special jacket with protective capabilities, an HD back and a large GN24 flash constitute a "megapixel" waterproof and dustproof digital camera.

Konica's DG-1 digital camera was launched in September 1998. It is also a digital camera with a 7-level waterproof and dustproof design, with a total of 1.08 million pixels. The fuselage and important parts are protected by hard rubber materials. Suitable for on-site monitoring of civil engineering projects. Images can be instantly transmitted and printed into project records and work report files.

In addition, some companies have developed special waterproof and dustproof jackets. For example, Kodak has launched a waterproof and dustproof jacket for three models of DC200, DC210Zoom, and DC210AZoom. 3 Canon The company has also launched special waterproof jackets for the PowerShot A5 and A5zoom models.

7. The advent of the new storage media "Memory Stick". Sony launched a new type of storage media - "Memory Stick" to the market in September 1998, with two capacities: 4MB MSA-4A and 8MB MSA-8A type. The volume is in the shape of a long strip, which is small and thin, and it is very convenient to pull out or insert. Technical characteristics: 10-pin connector, serial interface, maximum writing speed 1.5MB/S, maximum reading speed 2.45MB/S, power supply voltage 2.7-3.6V, average current consumption during operation is about 45mA, maximum standby time is 130mA, appearance Dimensions: 21.5×50×2.8mm; weight about 4 grams.

At the same time, MSAC-PCI type PC card adapter is also launched.

Sony's new SLR digital camera CyberShoePRODSC-D700 using "Memory Stick", 5x zoom lens (equivalent to 35mm camera focal length 28-140mm/f2-2.4), 1.5 million pixel CCD, 2.5-inch display, It is rich in functions and suitable for professional use such as photo studios.

8. Price positioning has generally declined. The initial price positioning of popular digital cameras was about US$1,000 for the US market and less than 200,000 yen for the Japanese market. The total pixels of product CCD image sensors at that time were generally 300,000-350,000 pixels. By the end of 1998, prices had dropped significantly. For example, the "megapixel" 3x zoom Ricoh RDC-4200 digital camera sold for a minimum of US$499. The market price of the same type of camera in 1997 was about US$1,300. It can be seen that the price over the past year The decline is huge. Many products add functions and improve performance while lowering their price positioning. For example, the DS-330 digital camera launched by Fujifilm in June 1998 is more convenient to use and lower in price than the DS-300 camera launched in April 1997. 5,000 yen (catalogue price 190,000 yen); the price of the 3x zoom CooLPIX910 camera launched by Nikon in October 1998 with many added functions is about 10,000 yen lower than the C00LPIX90 camera with a basically similar appearance launched in April of the same year. And the included CF card has also been changed from 4MB to 8MB.

The capacity of flash memory cards - CF cards and SM cards is increasing, and the price has also dropped a lot. The price in the US market is about US$7-10 per MB, which is down from 1997. About half. (Attachment: CF card: SanDisk Company of the United States provides a maximum capacity of 48MB; LexarMedia Company provides a maximum capacity of 64MB. Panasonic Battery Industry Company of Japan can provide 4, 8, 12, 16, 24, and 32 (MB) CF cards; Casio Company can provide 4 , 8, 15, 30, 48 (MB) CF cards. The main manufacturer, Toshiba Corporation of Japan, can provide varieties with a maximum capacity of 16MB. (2, 4, 8, and 16 MB are available in the US market. MB) SM card with four capacities).

(4) 1999 - the year of 2 million pixels. 1999 is the year when compact digital cameras entered the 2 million pixel range. In just over a year, the world's major camera manufacturers have put on the market far more than a hundred types of digital cameras.

In 1999, more than 20 kinds of lightweight digital cameras with more than 2 million pixels were introduced to the market. Each of them has its own characteristics and represents the progress of the times, such as Canon PowerShotS10, Kodak DC280, DC290Zoom, Fuji MX- 2700, MX-2900Zoom, PrintCamPR21, Nikon Coolpix700, Coolpix800, Coo1pix950, Olympus C21, C-2000Zoom, C-2020Zoom, C-2500L, Ricoh RDC-5000, Casio QV-2000UX, Sony Cyber-shotDSC-F55E, Cyber-ShotDSC-F505, Epson PhotoPC800, PhotoPC850, Konica Q-M200, etc. are all leaders in 2MP (MP means megapixels) lightweight digital cameras.

2. The Development of Popular Digital Cameras in 2000 From the birth of commercial digital cameras to the present, it has taken less than 10 years for the professional type and only about 6 years for the popular type. However, its development speed is astonishing. In 1998, the popular new product development hotspot was the 1 million pixel level. In 1999, the hot spot climbed to the 2 million pixel level (2MP). In 2000, it was upgraded to the 3 million pixel level (3MP). ), in October 2000, Olympus launched the CAMEDIAE-10 4x optical zoom popular digital camera with a total number of 4 million pixels, setting a new record in 2000.

(1) Development hotspots in 2000 Total pixels The hot spot in development was 3-megapixel (3MP) products. The first was the QV-3000EX digital camera launched by Casio in February 2002 (334 total pixels). Ten thousand). By the end of November 2000, 12 companies had launched more than 20 types of 3MP digital cameras.

The hot spot in lens development is the zoom lens. 80% of new models use zoom lenses.

Even cameras with single-focus lenses, most products also have digital zoom (also known as electronic zoom) function. The maximum optical zoom magnification is 10x.

The hot spot in the development of digital interfaces is that cameras use USB interfaces (Universal Serial Bus), or have both USB and RS232C interfaces.

(2) New design ideas 1. Appearance and external component configuration design are closer to 35mm cameras: the imaging quality of popular digital cameras and the A6 size photos printed are increasingly close to or equivalent to traditional 35mm In the camera class, popular digital cameras will naturally move closer to the traditional 35mm cameras that have been tested in long-term practice in terms of appearance and external component configuration design, and their usage habits are also roughly the same. Therefore, almost all famous digital camera companies have successively designed models similar to the "horizontal body" of traditional 35mm cameras. Such as the appearance of PENTAXEI-2000 integrated SLR digital camera and Kodak DC-4800 digital camera.

2. Design of new miniaturized and lightweight models: The image sensors used in popular digital cameras are all very small (1/1.8 inch, 1/2.7 inch, etc.), and there are no necessary requirements for traditional cameras. The indispensable film transport mechanism, coupled with the advancement of multi-layer board manufacturing and surface mounting technology as well as micro electronic components, have created excellent conditions for the miniaturization and lightweight of digital cameras. Therefore, new products are pursuing small, light, and fashionable products, and are moving towards Pocket direction development. For example: Fuji FinePix40i machine, volume 85.5mm×71mm×28.5mm, weight 155g; Kodak DC3800 machine, volume 95mm×61mm×31mm, weight 165g; Canon Digital IxUS machine (2x optical zoom), volume 87mm×57mmx26.9mm, weight 190g; High-ceramic Finecam3300 machine (2x optical zoom), volume 93.5mm×66mm×37.5mm, weight 200g.

3. Design and development of waterproof and dustproof digital cameras: In the past, Fujifilm and Konica have launched waterproof and dustproof digital cameras. In 2000, Fujifilm designed the 1.5-megapixel BigJobDS230HD, which is waterproof and dustproof. Ricoh designed the RDC-200G waterproof and dustproof machine with a total of 2.3 million pixels. The waterproof performance complies with the 7-level protection level stipulated in the Japanese Standard (JIS) C0920. In addition, Kodak has also developed a waterproof and dustproof digital camera.

4. Using the same body to design different models of digital cameras has become an important method to reduce camera production costs. It not only speeds up the design, but also saves production costs such as tooling and molds. For example, Kodak DC260, DC265 and DC290 cameras use the same body; Canon S10 and S20 also use the same body, but the technical specifications and performance are different.

3. Development Milestones

Sony MABIKA—the world’s first electronic camera that does not use photosensitive film

In November 1973, Sony The company officially began research on "electronic eye" CCDs. Based on continuous technology accumulation, it launched the world's first electronic camera without photosensitive film in 1981 - the static video "MABIKA". The camera uses a 10 mm × 12 mm CCD sheet with a resolution of only 570 × 490 (279,000) pixels. It is the first time that optical signals are changed to electronic signal transmission.

Following this, companies such as Panasonic, COPAL, Fuji, Canon, and Nikon also began the development of electronic cameras, and successively launched their own prototype electronic cameras from 1984 to 1986.

Sony MYC-A7AF - for the first time, a digital camera has a purely physical operation method

The second camera that is a milestone in the history of DC industry development is also made by Sony. It can be seen that the market position the company has achieved today is by no means a "wasted reputation". In 1986, Sony released the MYC-A7AF, which for the first time gave a digital camera a purely physical operation method, capable of recording still images on a 2-inch disc, and the pixel resolution has been expanded to 380,000 pixels. Casio VS-101 - the first CMOS sensor electronic camera.

In 1987, Casio was the first to launch the VS-101 electronic camera using a CMOS sensor on the market. Although the resolution could only reach 280,000 pixels, this was of great significance to the DC industry.

Today, in addition to being widely used in today's Canon high-end cameras, CMOS has been used by other manufacturers as the leading direction of their products.

Canon RC-760 - the first 600,000-pixel model

If you want to obtain a shooting effect close to that of a traditional camera, increasing the CCD pixel resolution is the most fundamental solution. , it was not until 1988 that Canon launched the 600,000-pixel model RC-760.

This electronic camera uses a 2/3-inch 600,000-pixel CCD. Its appearance may seem dull today, but it was the highest-pixel machine of that era, and its price was less than a small car today. expensive.

Kodak DCS 100 - established the general model of digital cameras

Kodak DCS 100 - established the general model of digital cameras for the first time in the world

1990 In 2006, Kodak launched the DCS100 electronic camera, establishing the general model of digital cameras in the world for the first time.

For professional photographers, if a new machine has a body and control mode they are familiar with, it will undoubtedly become easier to get started. In order to cater to this consumer psychology, Kodak used the well-known Nikon F3 body for the DCS100. Except for the focusing screen and film winding motor, all internal functions were the same as the F3 and were compatible with most Nikon lenses are really well thought out.

This digital SLR used a 20.5 x 16.4mm CCD with 1.4 million pixels and an optical zoom factor of 1.8X. However, due to the technical level at the time, it was not equipped with built-in memory and could only be used together with a bulky External storage unit (DSU) used. The DSU is similar to today's camera base. It uses batteries as driving energy and has a built-in 200MB memory that can store 150 uncompressed RAW photos.

Compared with today’s machines, the viewfinder mode is also very primitive. The photographer can use the optical viewfinder on the camera or the 4-inch LCD screen on the DSU to view the view. Although it is not very convenient, it was useful at the time. Very high-end. The price of this machine at that time was equivalent to 225,000 yuan today, which was really ridiculously expensive.

After the success of the DCS100, Kodak launched the follow-up model of the DCS100, the DCS200, in 1992. It finally got rid of the burden of the DSU, and the memory was placed inside the fuselage, so that it could be taken with you when shooting. It became very comfortable.

Nikon/Fuji E2/E2s - a digital SLR jointly produced by Nikon and Fujifilm

Both Kodak and Canon used the original traditional camera design in their early product designs. Film bodies, although this can make professional photographers feel the affinity of the product, but too many products will inevitably make people feel boring. In 1995, the two giants Nikon and Fujifilm jointly launched the newly designed E2/E2s. It no longer copied the old traditional body and adopted an integrated design style, which easily gave people a refreshing feeling.

The resolution of this digital SLR is only 1.3 million pixels, which is very different from the 6 million pixels of the contemporary Kodak DCS460. The most special thing about E2/E2s is that it uses Nikon's newly developed ROS optical system, which projects light onto a CCD with an area smaller than 35mm film through a set of optical elements. On this basis, the angle of view of the lens can remain unchanged, but is limited to the effective The aperture is severely reduced, and the image quality is greatly affected.

Nikon D1 - Nikon's first self-developed digital SLR

In June 1999, Nikon finally launched the company's first self-developed digital SLR-D1. The price of Kodak DCS series cameras has created a new era of civilian use of digital SLRs.

The body used in this digital SLR is modified based on the traditional camera F5, and it still maintains a very attractive and professional temperament. It has a built-in 2.74 million pixel CCD, an ISO sensitivity of 200-1600, and uses CF card/IBM microhard drive as storage media. It supports three file formats: JPEG, TIFF, and RAW. It costs US$5,580, which is still expensive today. .

Canon EOS 1D - Canon’s digital single-shot myth

In order to completely surpass the myth created by Nikon D1, Canon launched EOS specifically for fast shooting in September 2001 1D, thus surpassing Nikon D1 in terms of speed and technical indicators, becoming a new generation legend in the DC industry.

This digital SLR has a resolution of 4 million pixels, an ISO sensitivity of 100-1600, and also uses CF cards/IBM microhard drives as storage media. The price is around US$7,000.

Olympus E-1——4/3 system masterpiece

In December 2003, Olympus released the adoption of the jointly developed product with Kodak and Fujifilm. E-1 of the "4/3 System".

The 4/3 system stipulates the area of ??the CCD photosensitive device, the distance between the CCD and the lens, and the diameter of the lens. Therefore, any digital SLR using this system can easily achieve mutual compatibility of lenses. , which was absolutely unimaginable in previous products.

E-1 uses a 5-megapixel CCD with an ISO sensitivity range of 100-800. It uses CF cards as storage media and supports JPEG, RAW, and TIFF file formats. The price at the time of release was as high as 16,000 yuan.

Canon EOS 300D - the digital SLR king of the generation of civilians

The digital SLR is powerful and the shooting quality is beautiful, but the high price makes it unable to reach the common people. The biggest obstacle.

In order to successfully complete the popularization process of digital SLRs, a number of reasonably priced civilian digital SLRs have finally emerged, and Canon E0S 300D is undoubtedly the forerunner of this process.

In August 2003, Canon launched the EOS 300D with a plastic body, which integrated the CMOS sensor commonly used in the predecessor EOS-10D and sold for less than $1,000 for the first time, thus revolutionizing digital cameras. The original competition pattern of the market.

This camera uses a 6.3-megapixel CCD, an ISO sensitivity of 100-1600, and uses a CF card as the storage medium. The exterior design uses silver, gray, and black colors, and the overall feeling is pretty good.
