Sigma UV filters?

I'm not a big fan of Uv filters, but at times I wish I had one just so I didn't have to be so "careful".

The sigma ones are pretty well priced. I haven't bought a uv filter becuase I've been convinced unelss I get some pricy hoya I'll lose quality on my good glass.

What are the sigma filters like? I will soon probably have a few sigma lenses of myself. I'm just worried about losing quality / getting some weird effects like others here have experienced because of a crappy UV filter. It would make no sense though if you got degradable image quality on a Sigma lens with a sigma UV filter, wouldn't it?

Not necessarily. Canon makes lousy/flimsy UV filters in my opinion. The coating started to look mottled after a while. I just replaced them with B&W filters.

A cheap filter's a cheap filter, no matter who makes it. Filters aren't "tuned" for specific lenses, so using Sigma filters on Sigma lenses isn't a guarantee of quality results. For that matter, I've heard that Sigma, like Canon, actually gets their filters from other vendors rather than making their own.

The cost of better filters is for perfectly flat and strain-free glass with parallel surfaces (to minimize optical distortions), and multicoating to control reflections leading to flare. If you only want to use a filter when you are venturing into really lousy conditions, then maybe you can get away with a cheap one. But if you want to use the filter most of the time, or the bad conditions are also conditions that might lead to lens flare, save yourself the expense of buying cheap filters you need to replace because they're degrading your images.

Guess I'll stay with hoods then and get a filter for when I am shooting in bad conditions or need to get up too close.
