Today, despite the lack of autofocus, I must have shot 150 pics without focusing, because with good light, DOF is huge. It was just a point-and-shoot camera...:-) Otherwise, the camera recognizes the lens for Av, Tv, P, EXIF, just like a Canon, but not for the "intelligent" functions, such as vignetting correction. If you look at the EXIF of the shots I posted, you see the focal length, but not the "name" of the lens, as you would with a Canon. I am sure you will enjoy yours, it really has me enchanted and spellbound well beyond what my efforts show.
