Re: What is the lifespan of an EF 50mm f/1.4 USM?

Depends!

I have two, the first one has been repaired many time over 10 years, focus motor (well that is what it is called), the gear goes out of round and jams. As many people have said, don't push on the front of the lens.

I don't use either of them that much becasue the focus speed is slow, inaccurate and not consistent. Very bad CA until you get to approx f2.2 or 2.4.

If you shoot at night without any bright lights in the scene you get excellent results which you would not normlly get.

Contrast is very bad until f2.2
