I haven't seen this discussed much here so I thought I'd start us off. After you've spend 25% more than you originally thought you would to get that really neat lens, the thought of dropping $25-80 more on a protective filter can be heartbreaking. I started off with the "Digital Concepts" brand (hey, it was cheap!) - but I just bought a Hoya lens filter after listening to my local camera gal. I looked at two filters side by side and did notice a slight difference in clarity. I thought if my eye could see that much difference, a digital sensor might see even more when recording 8.2 megapixels. Any thoughts on good brands and quality? Or are the differences in filter brands just hype?
