Customer Reviews

High quality filter, awesome price
I got these filters for $4.95/per and I couldn't be happier. I have used B&W filters in the past, and while these are not quite in the same league, they are awfully close. Well-built, good multicoating, what more can you ask? If my Sigma 50mm macro is any indication, Sigma knows a thing or two about making glass. If you need something affordable and high quality, look no further. I see absolutely no difference between these and the more common Hoya S-HMC filters (which I also own).

EXCELLENT FILTER, EXCELLENT PRICE!
It is a known fact with photo enthusiast that Sigma is a fine maker of lenses. This also holds true for this filter. It is well built, sturdy with a high quality glass, perfect if you want to protect the lens of your camera without spending a hefty amount on filters. Plus it does UV filtering too without any degradation on your pictures. Can be kept always screwed in your lens. Overall, it is a best buy, highly recommended.

Sigma EX DG 55mm Filter
Great price compared to retail stores. Fit perfect and does the job. I purchased this mainly to protect the lens surface, plus I get UV filtering too.
