I am doing a lot of research on lenses for a Nikon D810 I have bought. I've exhausted DXO Mark. Does anyone know of other companies that test lenses and provide accurate data about lens sharpness, chromatic aberrations level, etc? I'm ultimately looking for a 21mm wide angle that is crazy sharp but am having a hard time finding one I think I would be satisfied with. Any help appreciated.
My suggestion is buy the lens from B&H and you test that sample for sharpness with lens testing chart. You will find variation from lens to lens.Do that till you get that super sharp one you want.
