Hi, we checked the sigma art 24-35mm f2 lens size is 82mm, please reconfirm it , if the lens size is 82mm, this square filter holder system kit can fit it ,thanks. 

Hi, this pro square filter system is not compatible with ordinary square glass filters. Need a K&F protective frame will be needed. We have individual protective frames for sale. 

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.
