Canon 16-35L filter recommendations

Hello, I got the green light from the wife to get this lens (thanks!). What protection filter and polarizer do you folks recommend? I have the B+W multi-coated for my other L's. I am concerned about vignetting.

Thanks for the ideas!

On a fullframe Camera you need a slim filter on this lens! Why protection filter? You know about the disadvantages? => https://photography-on-the.net/forum/showthre​ad.php?t=807726

These B + W's at 2 filter.com are slim, and have external threads so you can use a pinch lens cap. Their prices are excellent; they're in New Hampshire and are an authorized dealer for B + W. I get all my filters there.

The issue with this lens, I've found, is the hood. Using the hood increases vignetting. If you shoot in a room with white or light walls wide open, you'll see the difference in vignetting with and without the hood. The hood is so shallow that I don't think it does anything anyway, so the advantage of a protective slim filter that can hold a lenscap is significant. I don't use the hood any longer.

You don't need a UV filter unless you're still shooting film, DSLR's aren't affected by UV light. Get a clear filter.
