I bought Amazon basic 52mm filter for cannon 24mm stm, 2.8 lens. If you want to use this filter, make sure you know the maual mode settings on DSLR. Please do not use this filter on any of automatic setting. ISO, aperature, shutter speed should be fixed for this filter. Don't trust negative comments, because the might be using on automatic setting on DSLR. So, go for this fillter enjoy.
