The Canon EF 50mm f1.4 USM lens is great. Obviously it is a higher price than the 50mm f1.8, but it offers a greater overall image quality, even at f1.4 aperture. A lot of our customers buy this lens specifically for the shallow depth of field at large aperture, so it is nice to know that the lens is still sharp at f1.4 aperture. This is an easy lens to use in manual focus because of the full time MF ring. Why not come in to the shop and compare it to the 50mm f1.8 version.
