Does anyone know if I need to get a slim filter for this or will a normal 82 mm work. I just picked up the lens used and now need a filter but am concerned about vignetting at 16 mm....I appreciate any owners responding. Thanks a lot ...Brian
Thanks guys .....I shoot with an N and 40D's so it should work out ok..... PetKal,
Andi Dietrich...your responses are appreciated. This forum is such a valuable tool and so many willing people to help a person out. Brian
Regular filters WILL vignette on full frame with the 16-35 II. It's not a lot, though, and I much prefer using traditional lens caps over the minor vignetting it does cause.
Heck, it depends on your definition of vignetting. All black? No problem. Slight darkening? Wide open, even with a slim filter on a FF camera. Will you be able to notice in real life? Probably not.
Stanj, that's really narrowing it down . If you don't see it in real life, then you shouldn't worry about it. In my tests, the regular filters slightly vignette the edges when shooting my white wall compared to the slim filter. It's not noticeable on any of my shoots, so it's kind of a moot point and I get to use normal lens caps. The measurebaters will mind, though.
My filter does not cause any vignetting, and the Contax is a regular UV filter. Of course anybody's experience is just as good as mine

Vignetting is worse wide open. How's that on the 5D @ 16mm?
The OP wanted to know if a filter causes vignetting. He did not want to know if the lens has a vignetting problem, 2 pairs of shoes. IMO the vignetting is very well corrected on that lens

Really? How so? How does one "correct for" vignetting?
If a filter were to cause vignetting, it would be worse wide open than stopped down, as was said. It would be worse with a thick filter than with a thin filter, too. Start stacking enough filters and every lens will be vignetting - I can show you how the lens looks with a Vari-ND attached, if you wanted to see vignetting. The OP wanted to know if a normal filter was already such a "stack".

Well, speaking theoretically you are probably right. however I never noticed any vingetting from this filter on this lens, that's what I say. Maybe your filter does vignette, that s ok for me!
My experience with the 17-40 on my FF and a hood which people use on a crop body is that indeed vignetting is worse when stoped down, the same goes for the 16-35II. I can only guess that the position of the aperture may be part of this mystery.
If people are afraid of mechanical vignetting they should use a slim filter
I just wanted to make sure, so I did a little test with my 16-35II and my normal Contax UV filter. I dont see any vignetting from my own standard filter.
Frame 5 and 6 were taken with the hood turned in a 45 degrees position to introduce some mechanical vignetting, which is of course much stronger than what you would see with an average filter. Is it better at f22?
All lenses vignette some, and when you add a filter on it they vignette more. I have a 16-35L II and bought the regular filter because I don't like the slip on lens caps. Yes it vignettes some, but it did before I put the filter on. It may vignette a little more, but not enough to overcome the hassles of the slip on lens caps.
