The AF feature of my 50mm f1.4 was not stable - sometime it was fast (as before), sometime it tried but couldn't make focus (just heard the click click sound in the len) and sometime it didn't move like in MF mode. This len worked fine in my 10D for several hundards photos, but didn't know why it was not unstable from last 2 weeks :(. Any idea ?
