Polarizer Problem
Yesterday I had a problem with my autofocus locking into clear focus with my circular polarizer on. I shoot a D100, and had my 80-400 VR lens on. It seemed if I was zoomed all the way out at 80mm, the focus was clear. But if I was zoomed in at all, the focus was blurry. I was shooting handheld, but at shutters of around 1/800, so camera shake wasn't an issue. And when I took the polarizer off, there was no problem. I'm cleaning the camera and lens today, but I could see no visible dirt, dust or fingerprints on the lens or filter that might cause it to not lock on the scene clearly. I wasn't in a situation that I could have manually focused as I was shooting action shots. Here's a shot of a tree I took off to the side just to check if the autofocus would lock on. After this I just removed the filter so I could shoot the event. Any ideas? Thanks for the help! -K
