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

fell in love with it from the first use! I put it on a brand new mark 3 and made sure that they fit perfectly to each other, and no elka is needed! :) Has pros: sits perfectly on the camera, perfect assembly: nothing knocks, does not fidget, Vignetting at full frame, which makes portraits better (does not require post-processing) suitable for any situation, except for remote shooting. Different cons: at first, the focus stuck when I put on a filter or lens hood, but over time everything went away
