I've used B&W, Tiffen, Hoya, and I can say that Sigma filters are far superior by a long shot! Whenever I need a filter I look on Amazon for a Sigma filter. It's so crystal clear, easy to clean, and it looks just like the front element itself. No ghosting with these filters. I also think that they are moderately priced. Yes they aren't as cheap as the Tiffen's, but they are less and better than the Hoya's and B&W's. By far my favorite filters!

I have used various filters in the past and I find the Sigma EX DG filters to be a great deal and of excellent quality.
I use Sigma EX DG multi-coated UV filters on all my lenses. I try to take good care of my filters and lenses so I have not yet seen any scratches on these filters but they do have a multi-coated glass to help prevent that. They do help keep my good lenses free of contaminants on the front element. I tend to not use lens hoods so I feel I have a little protection having these filters on to prevent damage to my front elements.
This is the one item I include with every new lens I purchase. I usually follow this up with a Marumi DHG Super Circular Polarizer CPL as I find they are the best polarizer for the money.
I highly recommend these filters and I suggest you DO NOT go and pick up the cheap Rocketfish filters from Best Buy for example, they are a waste of money. Why put cheap glass on an expensive lens? SIGMA FILTERS ARE OF EXCELLENT QUALITY.

The Sigma EX DG 82mm MC filter works as it should, though I should emphasize that I haven't compared this to any other filter. It seems like it does what it needs to do - protect the lens while not adding unwanted aberration or artifacts. It's living on a Sigma 10-20mm zoom and seems quite happy there. I ordered a cheap 82mm filter at the same time as this one so I'd have a quick back-up in the event this becomes unusable at some point. Maybe I'll set up a test and see if I notice a side-by-side difference. I hope so since the Sigma filter was about $30 more!

I find them to be comparable to the multi-coated F-Pro filters from B&W, but at a much better price. I use them primarily for lens protection. It's now between those and the Hoya Pro1 MC Protector filters whenever I need a new one, making the ultimate decision based on lower price.

Upon reviewing numerous 82mm UV filters, this seemed best to me. From uncoated cheap-o filters for simple lens protection (and attendant distortion) to "pro-grade" filters (where's the price/quality ledge...?), I chose this one. Fits, works. Good service/delivery.

This is a great 82mm UV filter -- I got it for my 24-70 Sigma lens, and it works beautifully -- Before this, I had a cheaper Tiffen UV haze filter for this lens which would have lots of flare, and which caused weird anomalies in photos often making them MORE hazy...Sigma is a great brand, and their equipment just plain old works. This is a very good filter.
