I'm not sure if this is the right place to post this, but I was looking for some help with a problem I'm having. I own a D7000 which has been functioning properly since I purchased it a few months ago. I own a Nikon 35mm 1.8, Tokina 100mm 2.8 macro, Sigma 10-20mm all of which are working properly, focusing perfectly. I picked up a used Sigma 70-200mm 2.8 EX DH APO Macro HSM II last night and have been having problems with it. The lens shoots sharp as a tack when I manual focus, but when I switch to AF every shot comes out slightly blurry.
I have tested the lens hand held, tripod mounted, etc etc etc with the same results....every shot is blurry when using AF. When I manual focus the camera to perfect (to my eye) focus, then half depress shutter to AF the camera takes the lens out of focus to the slightly blurry focus and locks in to "focus". I'm very new to the dslr scene, but I'm pretty sure this is a lens problem with this particular Sigma. Is there any way to correct this or is this something that a trip back to the manufacturer can correct?
I want to have all the facts before I decide what to do with the lens, whether I can correct this with in camera settings or return it to the person who I purchased it from, or send it out for repairs and ask the seller to pay for them. Any information you guys/gals could provide would be greatly appreciated.
Thanks in advance, Dennis
