70-300 is usm lens question
Apr 2, 2010

I just purchased the canon 7d and the 70-300 is usm lens. I am a newbie so please forgive me if this is a stupid question. I am using the lens in autofocus mode and everything seems to work OK. However, when I turn off the camera I am putting the lens down to the 70mm setting and powering off. When I do this the lens is not fully retracting. Is this normal? The only way to get the lens down all the way is to put the lens in manual focus mode and turn it down manually.

I would think that the lens would fully retract in autofocus mode. Please let me know if this is normal or do I have a defective lens, etc.

Thanks!
