What about the Canon 40 F2.8 lens?

Canon EF 40mm f/2.8 STM lens is a cheap fixed-focus lens. Because of its light and thin structure, it is nicknamed biscuit lens.

As can be seen from its product code:

1, which is Canon EF bayonet, can satisfy the holographic field;

The focal length of 2.40mm is larger than the standard 50 fixed-focus viewing angle;

Maximum apertures 3 and 2.8 maintain a moderate depth of field. Although the blur effect is not as good as that of Jiao Wai (50 1.8), you can get more image content when shooting in the street.

4.STM focusing motor has high speed and low noise.

The same is true in practical use. With the profound connotation of Canon lens, to make a lens with a moderate aperture and focal length is like killing a chicken with an ox knife. Besides Jiao Wai blur, the color and sharpness are also satisfactory. When shooting in the street, it is relaxed, casual and less aggressive; On the APS-C frame, the equivalent focal length is 64mm, and it can also be used as a portrait lens.
