Lens Calibrating - 07-11-2007, 09:31 AM


I've seen threads about having it done. Is this something that needs to be done after a certain period of time? I have a Sigma 70-200 f2.8 and have always have great shots with it. I shot a lot of motor sports so I pan most of my shots. I know I'm not going to get a perfect shot every time but it seems lately I'm getting more out of focus shots then I have in the past especially using a flash. The lens is about 3 1/2 years old. Does this sound like what I need done?
