So before I do anything rash over the phone with Nikon, I figured I'd throw this on the table. I have a 105mm f/2 DC lens that is front focusing. I have tried it on 2 different cameras, my D2X and D200. Does the same thing on both cameras. My 24-70, 70-200, 12-24, a sigma 18-50, and my now gone 300mm f/4 all focus spot on with these cameras...no issues. I sent it to Nikon and they checked it to the tune of $191 The lens is still doing it....so unless all my other lenses are screwed up in screwy sync with my other 2 screwed up cameras, I think Nikon has REALLY done me wrong here. They say "lens is fine". Does it really cost $191 to determine a lens is "fine"? I can't get a picture in sharp focus on a tripod to save my life...takes over f/3.5 to get the eye in focus "somewhat". At f/2 of f/2.8, forget it...you only get the lips in focus (and boy are they sharp). No, the lens is not under warrranty. Focus is fast, lens appears fine, but this thing definitely front focuses on both my cameras and it is absolutely repeatable. So, what are the odds they tested this with a D3 or D300 and "fine tuned" it to say it's fine? I'm really angry here....Nikon took me for a ride and I just don't know what to do at the moment. What would you do?
