I use a supposedly non-reflective UV filter, but when I film towards light or the sun, I see big blotches that aren´t there when I detouch the filter.
Which good non-reflective 58mm UV filter can you recommend?
I have a bunch of B+W filters that are excellent (and priced accordingly). They're great and made with brass rings provided that you buy them from a reputable seller. Make sure that you get the ones with 010M (multi-coating designation), not the 010s. I also have a Sigma DG 52mm lens which seems to be great quality as well, so I'd think that the 58mm would be just as good.
