Hello photographers,

I'm thinking of getting the Nikkor 17-55mm 2.8 lens, and would also like a B+W Kaesemann circular polariser for it. What I am wondering about is: is it necessary to get the slim Kaesemann, or would the regular one do?

If I understand correctly, the slim version prevents vignetting on wide angle lenses; but I'm still wondering whether vignetting will occur at 17mm, if I use the regular version.
For any given lens, what is the absolute minimum focal length at which the regular Kaesemann won't produce some vignetting?

Both versions are 77mm:
Regular:

we don't know which camera you are using, and crop factor could make a huge difference.

my canon FF camera does not vignette @ 16mm with regular CPLs but i've never used the filter you mention and it could make a difference. also, it could be different with nikon lenses.

I get no vignetting AT ALL even at 10mm with my regular CPL.

Thanks for the replies guys.

My camera is the Nikon D300, which is a DX camera.

I said I wonder if the 77mm regular Kaesemann will vignette at the 17mm focal length of the 17-55mm Nikkor. And now that I think about it, I also wonder if it will vignette on:

- 16mm focal length of the 16-85mm Nikkor
- 11mm focal length of the 11-16mm Tokina

Hola Nicolas,

What brand of regular CPL do you use?

Hola Nicolas,

I use Tiffen's 77mm regular CPL. I think it is this one: http://www.bhphotovideo.com/c/product/56637-REG/Tiffen_77CP_77mm_Circular_Polarizing_Glass.html
