I've checked several sites, including the Sigma site, but I see nothing about two different types of UV filters. They are all listed as EX. Perhaps someone else knows something. Is the non-EX an older filter?

I am currently using sigma UV filters. The EX appears to be the current designation which preceded the DG. Since my interest when I purchased the filters is that they are multi coated (MC) and I bought in three sizes 58mm. 67mm and 77 mm, they gave a mix of the EX and the DG. I was told they were all the same and it was only a matter of branding. In use, EX or DG gave me the same results.

Hi

Thx 4 quick answer

In this SIGMA site http://www.sigmaphoto.com/sigmaonlinemall/default.asp?id=19&id2=32#32
In the title its written DG UV Filter, but if u make close-up on the picture u can see that on the ring of the filter theirs EX and the size is 77 mm.
I think all the pictures in the different sizes are the same picture.
My filter is 58 mm . can it be that on some sizes they write DG and on other ( big ) they write EX ?. My filter size is 58 mm and on the box it's written
Ultra-low Reflection Multi-Coating is that means it’s the same as EX ?

:confused:

Have wonderful sunny day
