Characteristics of digital SLR digital camera

First, the advantages of digital SLR digital cameras

1. More accurate framing

The unique reflector and prism design of SLR camera allows photographers to directly observe the image through the lens from the viewfinder. So the images seen by the photographer are completely consistent with the images taken.

Ordinary digital cameras can only see the captured images through the LCD screen or the electronic viewfinder (EVF), which is different from and not completely consistent with the images captured by the camera lens.

2. Higher imaging quality

Image sensor (CCD or CMOS) is one of the most important core components of digital camera, and its size is directly related to the shooting effect. The larger the area, the higher the imaging quality, and the image sensor size of digital SLR camera far exceeds that of ordinary digital camera. Therefore, the number of sensor pixels of digital SLR is relatively large (currently the lowest is 6 million), and the area of a single pixel is four or five times that of a civil digital camera, so it has excellent signal-to-noise ratio and can record a wide brightness range. The image quality of a 6-megapixel digital SLR camera is definitely better than that of an 8-megapixel ordinary digital camera and a 2/3-inch CCD.

3. Rich lens selection

Ordinary digital cameras only have one lens fixed on the fuselage in advance, which is irreplaceable. The focal length and aperture range of each camera are very limited, so it is difficult to achieve the purpose of multi-purpose of one camera.

The lens of SLR digital camera can be changed at will (as long as the bayonet matches). Canon, Nikon and other brands have huge autofocus lens groups, from super wide angle to super telephoto, from macro to soft focus. Users can choose matching lenses according to their own needs and hobbies. You can use not only the original lenses, but also the lenses of professional lens manufacturers such as Longteng and Sigma.

SLR camera lovers are crazy about lenses. Each of them has several or even a dozen spare lenses. When shooting outside, one bag can take several shots. You can shoot landscapes from a wide angle, flowers and plants from a macro angle, and wild animals from a telephoto angle. ......

4. Excellent manual control ability

Most ordinary digital cameras mainly shoot automatically, and the function of manually adjusting parameters is very limited. However, due to the ever-changing environment and subject, it is difficult to adapt to the actual needs of shooting only in automatic mode, not to mention that many skilled "color friends" like to manually set their own shooting parameters to create unique photographic works. Ordinary digital cameras simply can't meet this requirement.

SLR digital cameras have very powerful manual adjustment ability. No matter the aperture size, shutter speed, exposure, iso size and metering method, it is easier to achieve the best shooting effect. Therefore, the function of manual adjustment has become an essential function of digital SLR and a professional representative. The reaction speed is fast.

5. Rich attachments

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.

Second, the shortcomings of SLR digital cameras

1. Expensive

SLR digital cameras are much more expensive than ordinary digital cameras. At present, there are as few as three or four thousand entry suits at the lowest end, and tens of thousands or even tens of thousands at the high end.

It is bulky and inconvenient to carry.

For the convenience of operation, most of the functions of SLR are made into buttons and placed on the fuselage, which is unlikely to be as big as an ordinary card machine, with relatively large volume and poor portability. Generally, you need a special camera bag after buying a SLR, which is generally not too small because there are many accessories!

3. The control is more complicated

Most ordinary digital cameras basically have no manual function, and they all shoot automatically. The shooting parameters are automatically set by the camera. You just need to choose a good scene and press the shutter. Although SLR digital camera also has automatic shooting function, it is generally not used because it provides a very powerful manual function. Photographers like to manually set their own shooting parameters, such as aperture, shutter, ISO, white balance, photometry and so on. Should be set when taking pictures. It is difficult for friends who are not familiar with the manual function to take good photos with it.

4. Large investment in the later period

Ordinary digital cameras are a one-time investment, and there is basically no need to invest after buying a camera. As for the SLR digital camera, buying the fuselage has just begun, and a lot of investment is needed to match various lenses-playing SLR is playing lenses! A lens, and expensive, and people who play SLR rarely have only one lens. When they start burning, they buy more and more.
