Hi all: I've used several brands of filters. I think the lower version of B+W is single coated instead of uncoated. It's pretty good and the coating is pretty tough. Hoya HMC and HMC super are good but is difficult to clean (I have read a few reports on this and the HMC super filter). Helopan is pretty good too and the ring is brass and thin. If you have the $$, I would go for Nikon. Really good filter.
Difference? I can definitely see the difference when I took off my junky sunpak filter and put on the Hoya HMC. The color was A LOT better. This is when I was using the 28-105 time. Hoya HMC and B+W, I really can't see the difference. I mainly use B+W on my lens 'cos the tougher coating. Image degradation? well, any extra will typically degrade the image. But honestly, 1 to 2% degradation really can't be spotted... at least not by me. :) better to scratch the filter then the expensive lens. Funny I even put a Hoya HMC on my trusty 50mm f1.8 II... :P just my 2 cents, Gary ----- Original Message ----- From: "Gary Fisher" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, March 28, 2004 3:43 PM Subject: RE: EOS Filter Question On Sun, 28 Mar 2004 18:30:42 Konstantinos Bibis <[EMAIL PROTECTED]> wrote: > - ------------------- > > What is the difference between the B&W UV uncoated vs the B&W UV multi > > coated filter?
