Lately when I use my sigma 70-300mm lens on my Digital Rebel it seems to have a problem auto-focusing. The lens will focus as if the subject was just in front of the lens and not in the distance. To get it to work on distant subjects I need to manually focus on the far subject and then switch to auto focus, Has anyone seen this before and what can I do about it. Thanks in advance,
