Are they really the lens that can deliver divine quality? I wish to have a prime L but it is too expensive for me....whatever I have now are doing a very good job for me so will the L do a better job? And in fact I am wondering will it be a waste for an L to mounted on a cropped sensor...I think many will disagree with me.
I don't think so. In fact if u need the range u would wish u have a crop sensor to mount to instead of a FF.
