Cost/Price Great Value No vignetting problems @ 28mm. Great with color film.

Not at this price.

For what it's worth, I bought this filter so long ago I don't remember how much I paid for it. I bought it more than three years ago shortly after the purchase of a Sigma 28-200. The $30 figure is really a guess. In absolute terms, I suppose one could spend three times as much money and buy a better filter. I'm not certain that it would be three times better. So why spend more? Over the years, it has served me very well. I have had no problems with it causing any flaring or vignetting, even at the shortest end (28mm) end of the zoom range. When used properly under proper conditions, it does exactly as it's supposed to. For instance, it can't deepen blue skies that aren't blue to begin with. This will provide just about any photographer with a great value unless you're on assignment from National Geographic .

Never needed.

Excellent quality and value. They work as good or even better than filters costing three times their price.

None so far.

I purchased several Sunpak filters, including polarizers, skylight, and black and white contrast filters in different sizes. I purchased them because I liked their price, which is much lower than Hoya, B+W, and of course, Heliopan. Well, these filters are great, I was very impressed with the high level of quality and craftmanship that they show, these filters are very well made in Japan, and look and perform as good as filters that cost three times the price. I highly recommend this filters, and the place where I bought them online, for their excellent customer service, www.2filter.com .
