Review on Canon EF 40mm f/2.8 STM Lens - Fixed Black (6310B002) for US Cameras by Chong Wong

I use it on 5D Mark3, I take photos, although it is intended for video. The lens is incredibly good for its price and ultra-compact size. Colors tend to be cold. Thanks to this and unobtrusive vignetting (which you absolutely don’t want to remove during processing), quite saturated blue around the subject is obtained even without a polarizing filter. Very sharp and contrast wide open, and slightly softer wide open. For plots, nature, and long-range portraits (well, sometimes average, if you crop the result a little) against the background of nature - this is an excellent budget option, which cannot be called budget at all! Justifies its price by 100%. Close-up portraits are not recommended. Geometric distortion, although small, but there. Suitable for shooting in a bright room.
