Sorry, but if that's the Sunpak uncoated UV filter you made a mistake. Oh, it's not an expensive mistake, but a mistake.lenses--they only had Sunpack available. Well, I know that sunpack
doesn't have the greatest reputation but I said to myself, If ****
can't tell the difference, I probably won't.
And while I'm no expert, I'm not just regurgitating what others have written. After Chris from Germany posted his evidence in favor of the B+W 010, I did some empirical tests of my own. On my G1, the Sunpak filter made CA worse than no filter at all. The B+W 486 improved it.
Sometimes you CAN see the difference. It may not be major, but it's enough to make me cough up the extra $20 in this case.
