100x100mm Filter Protection Frame 2 Pack Nano-Xcel Pro Series

SKU: KF31.038

Q
Has anyone experienced any colour casting with these filters? Also, any vingetting on ultrawide lenses such as the Tokina 11-16 / 11-20? Thanks
Answer Question
A
Works fine throughout the range on my 10-20 wide angle lens on a cropped sensor. Although I suspect that 10mm would be the absolute limit, any wider and I think vignetting would occur. I don't use the extreme 10mm end that often however I was expecting some vignetting but I seem to have been lucky and gotten away with it. This is a really nice set of filters. Hope this helps.
