Last year i went to a photo show, and ended up buying a couple of 180mm filters (just because they were soo cheap), an ND and a CPL filter.

Fast forward to tiday, the day of delivery of the new to me Sigma 8-16. Took the filters out, and while holding both camera and filter with my hands, as close as possible to each other, it seems to me that the filters are actualy large enough for the lens.

I do have to take a better look when there is some light outside (it's dark for a few hours where i live). Next step is to design a filter holder for the lens, and see if i can 3d print it. I wanted to sell the filters, but i might just change my mind.

This might be the only way to use filters on this lens (at 8mm), but it is not a nice combination, because of the huge size of the filters.
