Among other things, I shoot a lot of motocross throughout the spring and summer season. Pretty much most weekends. I have often thought that a drop-in circular polarizing filter for my 300/2.8 would be a good idea to reduce glare from goggles and face masks, as well as to enrich colours and perhaps tone down some highlights.
I decided to go ahead and have ordered one. As an afterthought (I have a lot of those), I was wondering if introducing that filter would have any negative effect on the speed and/or accuracy of the AF. Anyone out there with any experience with one that could answer that question for me?
