Hello again everyone, I have a question about the AF servo on my 20D.
Today I was shooting a dog show that had a choreographed Frisbees being thrown and the dogs catching them. I had my old 35-105mm push pull lens on the 20D. I was using servo, 400ISO in noon day sun with shutter speeds of 1/1000th-1/8000th, and F5.6 for a little depth of field. I was also using the center AF point only. Anyways, I got home today and looked over the shots, I got only 40% or so of the shots with perfect focus. Anyone know if it would be the lens' AF motor (old arc-form drive) or could it be something else?
I know that the ones that are focused on the background my fault, but the ones that looked focused in the screen did not come out that way.
Here is baiscally what I did, set the lens on 105mm and I just fallowed the dogs continually focusing.
Thanks for any replys.
