Good day guys! Here again for another newbie question. I have a question regarding full frame on Canon systems. As far as I know, with regards to the naming convention on Nikon lenses, a lens would be meant for full frame if it is labelled 'FX'...and for cropped 'DX'... please correct me if I'm wrong with my above statement... my question is, what is the naming/labelling convention on canon lenses when it comes to full frame lenses and non-full frames? thanks again for your help!!!
