What does a card camera mean?

Question 1: What does the card machine mean? Card machine: refers to those digital cameras that are small, light and ultra-thin and fashionable. Represented by Sony T series and Canon IXUS series. The main characteristics of card machine are easy to carry and weak function. Generally, it is automatic exposure, and there are few manual functions. Although its function is not strong, the most basic exposure compensation function is the standard configuration of ultra-thin digital camera, plus area or spot metering mode, and sometimes it can complete some photography creation. At least the exposure of the picture can be basically controlled, and with the options of color, clarity and contrast, many beautiful photos can also come from the card machine. Advantages of card machine: stylish appearance, large LCD screen, compact body, easy to carry and operate. Disadvantages: the manual function is weak, the lens performance is poor, the lens can not be replaced, the focusing and shooting speed is slow, and generally only the LCD screen is used for framing, and the LCD screen is very large, most of them have no optical viewfinder, and the LCD screen consumes a lot of power.

Question 2: What does the card machine mean? "Card machine" means that the camera is thin and small, like a card. This kind of camera has a fixed lens, generally rectangular, small size and retractable lens. Single-lens reflex digital camera is the main difference between single-lens reflex digital camera and other digital cameras. There is no clear concept of card digital cameras in the industry. Only those small shapes, relatively thin bodies and ultra-thin and fashionable designs are the main standards to measure such digital cameras. A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed. SLR is a camera-based structure with a large volume, and there is a mirror inside to reflect the picture to the viewfinder. The framing picture is the same as the actual shooting (on the 120 SLR, the picture is left and right opposite). Digital card camera is probably the floorboard of ultra-thin digital camera, which generally refers to digital cameras with small volume, light weight, few manual functions or full automation. Many low-end machines are also small in size and weight, and the relative thinness of card machines is its biggest feature. Card machines generally use lithium batteries to ensure that the camera is not too thick, and some use periscope lenses to further reduce the thickness, such as Sony T300, T2 and so on. At present, there seems to be no relevant standard for card machine. According to personal experience, the volume is generally not more than 95mm/65mm/25mm (length/height/thickness) and the weight is not more than165 g, so Canon's IXUS series are relatively thick card machines, which may not be considered as card machines compared with other brands.

Question 3: What's the difference between a card machine and a digital camera? Camera is an optical instrument for recording still pictures, which can be divided into traditional film camera, polaroid camera (Polaroid film) and digital camera (recorded as digital picture file) according to the recording medium.

As a main category of cameras, digital cameras can be divided into interchangeable cameras and non-interchangeable cameras according to lens configuration.

Digital cameras with interchangeable lenses can be divided into digital cameras with interchangeable single-lens reflective viewfinder (commonly known as digital SLR) and digital cameras with interchangeable single-lens electronic viewfinder (commonly known as single lens, Sony calls a miniature single lens a micro lens to distinguish it from a single-lens camera with similar SLR appearance but using electronic viewfinder).

Digital cameras with non-replaceable lenses are divided into ultra-thin digital cameras, commonly known as card machines, and large zoom digital cameras with large zoom ratio (more than 30 times). Because the equivalent focal length can reach 600- 1200mm (in fact, most of them also have a wide angle of 24mm), they are also referred to as telephoto digital cameras. This camera has a huge lens, but it can't be called a card machine. Its shape resembles a SLR, also known as a SLR-like camera.

Question 4: What does a digital camera card mean? Card machine is mainly light, fashionable, simple and easy to use, mostly stupid. There are telephoto cameras, quasi-professional cameras and entry-level SLR cameras in household cameras, which are very popular after all. The main difference lies in the simple operation and beautiful appearance of the card machine, which is mainly aimed at ordinary home users who don't have too high requirements for imaging effect, as long as it is simple and practical. High-end quasi-professional cameras and SLR are mainly aimed at photographers who have high requirements for photographic effects.

Question 5: What is a card machine? What's the difference between it and a SLR camera? SLR is very expensive;

-SLR cameras use single-lens reflection to obtain images of objects for observation and shooting.

-This was during filming.

-The card machine passes through the electronic viewfinder, and the SLR camera passes through the optical viewfinder.

Simply put.

-The lens refraction distance of the card machine is short when shooting.

-The scene must undergo multiple refractions and some image processing inside the camera.

-SLR cameras look directly through the mirror and experience a refraction.

And then perform secondary refraction through an internal pentaprism.

-Image interpretation.

-This is a SLR camera. It's like being there.

-It's like watching TV.

-SLR cameras have another advantage.

-You can change different lenses.

-And the card machine is impossible.

-The internal pentaprism will also make the image of the scene more vivid and full.

And the shutter will not delay, the reflection speed is fast and so on.

2. One of the advantages of the lens

SLR camera lens has a large aperture and a large amount of light. You can set aperture, shutter, ... and so on. Any parameters you want to set.

There may be some digital cameras with strong manual function, which can set the aperture and shutter, but there is no obvious effect.

For example, the effect of background blur, SLR is easy to do, ordinary digital cameras are difficult to do.

3. The second advantage of lens is that

SLR lenses are generally expensive, and the quality is good. The quality of the photos taken is exquisite, really.

Some ordinary telephoto digital cameras may be able to zoom easily, but at the maximum magnification, there are usually too many problems in the picture, such as the common purple edge.

It's mainly how you distinguish. If you just look at small photos, of course there is no difference. Zoom in and you will know the essential difference.

Question 6: What does the so-called outsole mean in the camera? Is it the difference between SLR and card machine? I don't know whether you read this statement online or in a book, but I think:

"Bottom"-should come from the size of the film negative.

What we use most often is that the width of the film negative is 35mm. You can watch old movies at home.

There are smaller and larger negatives (rarely seen)

In the digital age, photosensitive elements (CCD or CMOS) have replaced negative films, but there are also different sizes. Outsole and outsole should refer to the size of film negative or CCD/S.

In addition, the essential difference between SLR and card is not the bottom. This is the way to observe.

Single-lens reflex camera (this can be checked, there are many explanations and pictures)

Card-the body is relatively small and as thin as a card, hence the name.

Add one more thing:

The size of the "bottom" will determine the viewing angle and the ability to record details (just like two cups with the same height, the larger the bottom area, the more water will be filled), so many professional photographers will use the so-called "big bottom" camera to ensure that the picture will still have good clarity and details when put into a large size.

I hope this helps.

Question 7: What is the best card camera? 1. Card camera is a broad concept. Some people call it a card machine that can be put into a trouser pocket, while others call it a relatively small card machine with irreplaceable lens. Everyone's standards are different. Generally speaking, the card machine refers to a portable camera with an irreplaceable lens;

2. The landlord only asks what is the best, and there is no specific direction. I answer from all sides. It may not be comprehensive, but it is close. Some of them are controversial in the circle, such as the card machine DPM of X3 and the DPM of Sima. It is true that the official propaganda is comparable to the Chinese format, but in actual use, it needs to have a certain photographic foundation and post-production ability, and the control is not the best. In addition, X3' s weak light ability is impossible to hold night scenes, and its limitations are obvious in use, so many photographers disagree with X3' s image quality, which is understandable. As for some newcomers, they don't know X3 at all. They become. I won't repeat the rest, otherwise the space is too long;

3. The prices of card machines vary greatly, and different levels of card machines have the characteristics of different image quality, different control and different convenience. We can't generalize to say that one is better, mainly depending on what we are most concerned about and what suits us best;

4. Take the picture quality as the standard. The imaging quality of digital camera is determined by sensor, lens and image processor, in which sensor accounts for 45%, lens accounts for 50% and processor accounts for 5%. At present, among the mainstream card machines, Leica Q(typ 1 16), Sony RX 1RM2, Sigma DPQ/M, Sony RX 1R, Sony RX 1 and Fuji X/kloc-are the card machines with better image quality. Canon G7XM2, Canon G7x2, Leica D-Lux (Typ 109), Panasonic LX 100, Canon G 1XM2, Sony RX 100, Panasonic ZS1.

5. Take manipulation as the standard. Control mainly includes focusing speed, focusing points, regional focusing ability, shutter lag, continuous shooting speed, etc. It is related to the success rate of shooting, which is very important in dark scenes or shooting fast-moving pictures. Among the mainstream card machines, Sony RX 1RM2, Sony RX1005, Fuji X 100F, Ricoh GR2, Ricoh GR and Fuji X70 are well controlled, but other controls are very general.

6. Take portability as the standard. Pocket machines only include Ricoh GR2, Ricoh GR, Nikon CA, Sony RX 100M5/M4/M3, Canon G7XM2, Canon G7X, Panasonic ZS1/KLOC-0, Fuji X70；;

7. Take convenience as the standard. Most high-quality card machines use fixed-focus lenses with high resolution and aperture, but the convenience of use is not as good as zoom. From the convenience of using the focal length, it is Panasonic ZS/KOOC-0//KOOC-0/0, Canon G/KOOC-0/XM2, Canon G7XM2, Canon G7X, Sony RX/KOOC-0/00, Leica/KOOC-0/09 and Panasonic LX/KOOC-0.

8. If bridge cameras (telephoto cameras) are included, at present, the better bridge cameras are Sony RX 10M3, Panasonic FZ 1000 and Canon G3X, all of which are relatively good telephoto cameras (actually, they are not card cameras, but they still belong to the category of portable cameras that cannot change lenses). Shooting wildlife, birds and even paparazzi,

9. From the perspective of cost performance, Sony RX 1 has the highest cost performance, and Sony RX100; Less investment, the highest cost performance; For hobbies, the most amazing picture quality is Sigma SDQ/M; For tourists, the most practical focal length is Canon G1XM2; ; For the rich and local tyrants, Leica Q is the best choice. As for the face value, there is no uniform standard for each flower to enter each eye;

10, Sony RX 100M3 or canon G7XM2 are suitable choices for general household card machines, and factors such as portability, practicality, cost performance, image quality and control are comprehensively considered.

Question 8: Why is it called card machine? Card machine usually refers to ordinary consumer digital cameras. The image sensor size of card machine is generally small, and the low-end machine uses 1/2.3 inches; The high-end machine adopts11.8 inches. The way of framing is basically through the LCD screen. The image seen on the LCD viewfinder is an electronic image after passing through an image sensor and an image processor. It has a deceptive name "live view", but there is still a little delay. Moreover, because the color gamut of the camera LCD screen is too small, the color and details of the image you see are different from the actual subject. In addition, the lens of the card machine is fixed on the fuselage and cannot be replaced. Consumer digital cameras include not only card machines, but also

Telephoto machine (card telephoto machine and bridge telephoto machine).

The card machine has micro-single, single electricity and SLR on it. SLR is the abbreviation of single lens reflex, which usually refers to the interchangeable lens digital cameras of Quan Huafu and APS-C. "Single" refers to using the same lens for framing and imaging, and "reverse" refers to the reflector inside the camera. The image reaches the mirror through the lens, and most of the light reaches the Wuling mirror after 90-degree reflection (now the low-end SLR uses a five-sided mirror). After several refractions in Wuling mirror, it turns 90 to reach the viewfinder eyepiece. The image seen by a SLR camera in the viewfinder is a positive optical image, and the final imaging effect is almost the same as that seen in the viewfinder.

Single-lens camera, also called micro-single camera, is a new word, that is, single-lens electronic framing. As the name implies, it refers to a camera with mirrorless design, electronic viewfinder (EVF) and digital SLR functions (such as interchangeable lens, fast phase detection autofocus, large image sensor size, etc.). ). The biggest difference from SLR is that there is no reflector and five mirrors, including Panasonic and Olympus' 4/3 system micro-single, APS-C format micro-single and Nikon and Fuji's 1 inch sensor system micro-single. The micro camera is just a name given by Sony, and it is only used in Chinese mainland. In fact, it is also a kind of single camera, in order to distinguish its A series single camera from NEX single camera. At present, the name of micro-single has been widely recognized by merchants, and the standard name of the manufacturer is "mirrorless camera".

Question 9: What does the symbol function in the card camera mean? Let's read the instructions. If you want others to tell you these things through the internet, it will take many years to understand.

It doesn't matter if there is no manual, because there is an electronic version that can be read on the computer. Don't be too tired. Self-study is even more tiring.
