Classification of SLR cameras

SLR cameras can be mainly divided into the following three categories.

1, entry-level digital SLR camera

As the name implies, this camera is mainly aimed at entry-level users. This kind of camera is light, easy to carry and cheap. In addition, its performance not only retains the basic functions of digital SLR cameras, but also provides users with a variety of scene shooting modes, which can help beginners learn and improve their shooting skills step by step on the basis of ensuring smooth shooting.

2. Quasi-professional digital SLR camera

As far as the camera body is concerned, more metal elements are incorporated, and the camera body has better stability and reliability. In particular, they have more reliable dust-proof, frost-proof and splash-proof performance, which enables this camera to cope with more extreme weather conditions and environments.

3. Professional digital SLR camera

Matters needing attention in purchasing SLR cameras

1, image sensor area

The area of the image sensor is the main factor that directly determines the imaging quality. Whether it is CCD or CMOS, the larger the area, the better.

2. Pixel size

At present, mainstream SLR digital cameras should generally be more than 6.5438+million pixels, but the bigger the pixel, the better. In the case of the same image sensor area, the larger the pixel, the worse the imaging quality.

Step 3: lens

There are two ways to sell SLR digital cameras: one is to sell the body separately, and users need to match their own lenses; The other is a set machine, which is equipped with a lens in addition to the fuselage. However, the matching lens grade is not too high, which is a relatively cheap product, but the kit is cheaper and more affordable than buying the same body and lens separately, which is suitable for users with insufficient funds.
