Beginners of photography must know the difference between digital micro-single and SLR.

As a beginner in photography, your first choice in camera selection is SLR camera, but if you want to be an excellent photographer, then you must understand the difference between digital micro-camera and SLR.

First, the concept of digital micro-single and SLR

digital camera

Digital camera, English full name: Digital Still Camera (DSC), short name: Digital Camera (DC), short name of digital camera, also known as digital camera. Digital camera is a kind of camera that uses electronic sensors to convert optical images into electronic data. According to the use, it is divided into: SLR camera, micro camera, card camera, telephoto camera and household camera. The principle of digital camera recording images on film through silver bromide's chemical changes is different from that of ordinary cameras. The sensor of digital camera is photosensitive charge coupled device (CCD) or complementary metal oxide semiconductor (CMOS). Before an image is transmitted to a computer, it is usually stored in a digital storage device (usually using flash memory; Floppy disks and rewritable compact discs (CD-RW) are rarely used in digital camera equipment.

Micro single

Micro-single contains two meanings, micro, compact, single-lens and replaceable single-lens camera, that is to say, this camera is small in size and its imaging quality is similar to that of SLR. That is, a micro camera with SLR function is called a micro single camera. Micro-camera is between card-type digital camera and SLR camera, just like netbook appears between notebook computer and smart phone.

SLR cameras (SLR cameras) are also called SLR cameras. It is a camera that uses a single lens and reflects the view through this lens. The so-called "single lens" means that the photographic exposure light path and the framing light path * * * use one lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens. "Reflection" means that a plane mirror in the camera separates the two light paths: when the mirror falls during framing, it reflects the light of the lens to the pentaprism and then to the framing window; When shooting, the mirror rises quickly and the light can shine on the photosensitive element CMOS or CCD.

Second, the difference between SLR and micro-single.

Micro single

1, price

A SLR of the same grade, divided into miniature SLR cameras. Professional SLR is definitely much more expensive than professional micro-single. There is no doubt about it. It can be said that at the same price, the grade cost of SLR is definitely more expensive than that of miniature SLR. Because the internal structural materials will affect.

2. Volume and weight

The size of the SLR is definitely thicker, bigger and heavier than that of the micro-single, because every penny is worth a penny, and all the good things are heavy inside. For example, the lens is longer and larger than the micro SLR, and the internal photosensitive crystal is larger than the micro SLR.

Step 3 show up

The SLR has been maintained? More solid and steady, the appearance is more powerful, and the shape is more deeply rooted in the hearts of the people.

The shape, style and color of the miniature SLR have injected a certain modern style, which can be said to be a commercial product integrating art and technology.

4. lens

Both micro-lens and SLR can be disassembled and assembled, but micro-lens has more lens selection space and better compatibility than SLR. The power of microlens microlens is that many old lenses can be reborn because of the smaller flange distance, as long as an adapter ring is added.

Compared with SLR, there are many lens bayonets, and different brands of bayonets are incompatible, which is a monopolistic development. Of course, SLR lenses are far more expensive than miniature SLR lenses.

5. Reflector

Between SLR and micro-single, it can be literally perceived that SLR has an "anti" word more than micro-single, and this anti is the meaning of reflector. The microchip has no reflector.

Reflector: As an auxiliary equipment in shooting, reflector is as common as flash. Using the reflector well according to the needs of the environment can make the plain picture more full and reflect the good image light sense and texture. At the same time, using it to properly change the light in the picture is also very good for concise picture components and highlighting the main body.

Its function is to reflect the light of the lens and make it visible to the naked eye under the eyepiece. Its function is to focus.

However, the microchip has no reflector and can only be viewed in digital DC mode through the LCD screen.

Third, the difference between digital SLR and digital camera

1, the picture quality is better.

Because the photosensitive element area of SLR (equivalent to the film size of traditional camera) is more than 10 times that of ordinary digital small camera, and Quan Huafu SLR is 25 times that of ordinary digital small camera, the image quality of SLR camera is obviously different from that of ordinary small camera. This gap is manifested in the purer picture, less noise, more complete and delicate details, richer color levels, higher tolerance and better image quality under high sensitivity.

2. The depth of field is greater.

You may have no idea about the term depth of field, but you should have seen many portraits with clear characters and blurred backgrounds-it is impressive to highlight the subject in this way. This kind of photo was taken by SLR. Because the focal length of the small camera is short, the photos taken by the small camera are basically clear in the whole picture, and only the SLR can adjust the depth of field to a greater extent to make the whole picture clear, or only the focus is clear and the background is blurred to highlight the subject.

3. Focus faster and continuous shooting stronger.

Because the SLR camera adopts the optical focusing module, the focusing speed is much faster than that of ordinary digital small cameras. The SLR processing chip is more powerful, and the continuous shooting speed is much better than ordinary small digital cameras. It's much easier to capture images that we can't capture with small cameras.

4, interchangeable lens.

When we buy a small camera, we never consider buying another lens. SLR is a system, and there are various specialized lenses in different fields: telephoto lens, wide-angle lens and macro lens. Although a small camera can also have telephoto and macro functions, it is just like the difference between a real gun and a toy gun compared with the telephoto and macro effects on a SLR camera.

Fourth, the difference between SLR and digital

Micro single

The professional positioning of digital SLR cameras determines that even popular products for ordinary users and enthusiasts have many advantages, which is also the fundamental reason why many enthusiasts choose digital SLR cameras. We can summarize the professional characteristics of digital SLR as follows:

1, advantages of image sensor

CMOS image sensor For digital cameras, the photosensitive element is one of the most important core components, and its size is directly related to the shooting effect. To achieve good shooting results, the most effective way is not only to increase the number of pixels, but also to increase the size of CCD or CMOS. Whether using CCD or CMOS, the sensor size of digital SLR cameras is much larger than that of ordinary digital cameras. Therefore, the number of sensor pixels of digital SLR is not only relatively large (at present, the minimum is 6 million), but also the area of a single pixel is four or five times that of a civil digital camera, so it has a very good cost performance and can record a wide brightness range. The image quality of a 6-megapixel digital SLR camera definitely exceeds that of an 8-megapixel 2/3-inch CCD camera.

2. Rich lens selection

Digital camera is a product of optical, mechanical and electrical integration, and the performance of optical imaging system is also very important to the final imaging effect. Having an excellent lens is as important for imaging as the choice of image sensor. At the same time, with the cost reduction of image sensor, image engine and storage equipment, the proportion of optical lens in the cost of digital camera is also increasing. This is especially true for digital SLR. In the choice of traditional SLR cameras, the richness of lens barrel and imaging quality are important factors in the choice of film friends. In the digital age, the retention rate of lens barrel naturally becomes the basis of brand competition. Canon, Nikon and other brands have huge autofocus lenses, from super wide angle to super telephoto, from macro to soft focus, users can choose matching lenses according to their own needs. At the same time, due to the large sensor area, it is easier for digital SLR cameras to obtain excellent imaging. More importantly, many photographers generally have one or two or even a dozen professional lenses, all of which are purchased by photographers with their hard-earned money. If they buy a digital SLR camera body, the lens will be revitalized at once, and they will form two complementary film and digital systems with the original traditional film camera.

3. Fast response speed

The biggest problem of general digital cameras is the long shutter lag. If you don't master it well, you will often miss the most wonderful moment. Response speed is the advantage of digital SLR. Because their focusing system is independent of imaging equipment, they can basically achieve the same response speed as traditional SLR, which makes users handy in news and sports photography. At present, Canon's EOS1D Mark Ⅱ and Nikon D2H can reach the continuous shooting speed of 8 frames per second, which is comparable to traditional film cameras.

4. Excellent manual control ability

Although the camera's automatic shooting function is getting stronger and stronger today, a user who has certain requirements for photography will not be satisfied with shooting only in automatic mode because of the ever-changing environment and shooting objects. This requires that digital cameras also have the ability of manual adjustment, so that users can adjust according to different situations to achieve the best shooting effect. Therefore, the function of manual adjustment has become an essential function of digital SLR and a professional representative. Exposure and white balance are two important aspects in many manual functions. When the automatic metering system cannot accurately judge the light and color temperature of the shooting environment, users need to judge according to their own experience and make mandatory adjustments manually to achieve good shooting results. This is also the embodiment of the professionalism of digital SLR. For example, EOS 10D can adjust the color temperature value on the basis of 100K every time to help users get the best effect.

5, rich accessories

An important difference between digital SLR and ordinary digital camera is its strong expansibility. In addition to continuing to use additional lenses such as polarizers and interchangeable lenses, you can also use auxiliary equipment such as professional flashlights to enhance your ability to adapt to various environments. For example, high-power flash, ring macro flash, battery handle, timing remote controller, these rich accessories make digital SLR adapt to various unique needs, while ordinary digital cameras are greatly inferior.

Five, the difference between digital and micro single

1, weight

Micro-cameras are heavier than digital cameras, but both cameras are small and portable.

2. Image quality

Due to the conversion between digital imaging elements and image processing chips, the imaging quality of digital images is less layered than that of optical cameras. Digital Due to the different image processing chip technologies of various manufacturers, the color of the imaged photos is different from the real thing. The "micro-single camera" adopts the same specifications as the SLR camera, and cancels the optical viewfinder component on the SLR camera. Without the structure of prism and reflector, the distance from the lens bayonet to the photosensitive element is greatly reduced. Therefore, you can get a smaller body than a SLR camera, and at the same time ensure the same image quality as a SLR camera.

Step 3 change the lens

Digital cameras can preview photos directly, but they can't change the camera lens, and micro-cameras can also change the lens like SLR cameras, providing the same image quality as SLR cameras.

6. Summary of the difference between digital micro-single and SLR.

1, micro-single is small in size, convenient and wide in lens range, suitable for ladies, ordinary families or amateurs.

2. The SLR is huge, the overall weight is heavy, the price of the fuselage and lens is relatively expensive, and the upgrade is convenient, which is suitable for photographers and professionals.
