im new to this lens so maybe im doing something wrong. Ive been using the 24-105 lens before this one and I can get the lens pretty much right on top of a flower or etc im focusing on. The 70-200 I have to be a good 4-5ft away to autofocus correct?
When im at this distance it seems to focus about 1-2inches behind what I actaully have centered to focus on. Im using the center spot focus dot on the 50d if that matters but it seems to ovbershoot the focus.
here is a example
I was focused on the flower and bee but it picked the buds behind the flower which are tac sharp. Ive tried a couple quick shots on distance objects and focusing is ok. Is this just a issue up close on objects? Do I need to send the lens back to get calibrated?
