Excellent lens, very typical of a Canon lens. Sharpness of this 25 year old lens is on par with current lens and product build superior. This lens will probably bee going strong 25 years from now.
LOVE THE WEIGHT OF THE LENS. ALWAYS BEEN A FAN OF MANUAL FOCUS, MAKES ME FEEL LIKE IM REALLY TAKING THE PICTURE AND IN CONTROL. AND THE FRAMING OF THE LENS IS REALLY COOL. SLIGHT DISTORTION AROUND THE EDGES AT 28MM. BUT IT ADDS A COOL EFFECT! BRAVO!
From many years of experience with this lens, I found it is a great, dependable, lightweight lens with a good maximum f-stop and a very useful angle of view. Probably the best wide angle lens to own if you are picking one wide angle lens for your Canon F-1, A-1, AE-1, AL-1, T50,70,80,90 or other FD lens mount cameras. If you go much wider, you may have problems getting your flash to cover the entire area of view. Since it is light lens and a very flexible focal length, you're more likely to want to carry it with you and have the benefit of its focal length at your reach.
