What does the letter logo on the lens of SLR camera mean?

1, EF: Quan Huafu lens, the most common Canon lens category, can be used for EOS series film SLR cameras, full-frame digital SLR cameras, APD-H (coefficient 1.3), APS-C (half-frame camera coefficient 1.6) digital SLR cameras.

2.EF-S: APS-C frame lens, which is specially designed for APS-C SLR cameras, commonly known as half frame or residual frame. The sensor area is 40% of that of Quan Huafu, and the price is cheap. It is also our common Canon lens.

3.TS-E: axis shift lens. My personal understanding is that the lens can be Bai Wan, then shift the angle of view and change the focus range, which can be used in architectural photography and other aspects.

4.MP-E: Macro lens, specially used to shoot the hair on the fly's leg.

Extended data:

Imaging mode of SLR camera;

The full name of a SLR camera is a single-lens reflex camera, which refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.

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, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.
