No negative effect on image at all!
I have not had a good day to test outside yet with actual Polarizing, but I have done macro level and 20 Ft testing and there is absolutely no change in image quality (even with pixel peeping). This was my biggest concern with this lens. The quality is amazing so far. One thing I have noticed is that when you put this filter on is that it does flex a tiny bit. This is not an issue until you try to take it off. If you try to squeeze the filter get a grip, it will not unthread. You have to be a bit gentle with it, then it unthreads without hassle.There was one tiny spec on the filter, but it does not seem to be effecting the image at all. I will update this post once I get more testing done.This was tested with my Canon 24-105 F/4 L with my 1DS and 50D.
