I can't seem to find a polarizer that doesn't vignette the edges of the picture when using the wide angle range on my Nikor 24-70 lens. I had a tiffin filter and recently purchased a B+W filter which didn't solve my problem I removed the UV filter first to keep the filter as thin as possible. The filter size is 77mm and I can't locate a step up ring to something larger or a larger filter. Any other suggestions ? I know I can crop out the center of the image and I am using a D800 but I have a habit of cropping pretty tight in the viewfinder. HELP

It woud be helpful to see an image of the issue.

Is it vignetting all aroud the image or is a fall of of the polarization effect that occurs with wide angle focal lengths?

I assume you do not see the problem in the viewfinder with the lens wide open but it occurs in the image when you stop down.

Stacking filters is not advisable. There is no reason to use a UV filter and a polarizer.

Just a thought to double check if the lens hood could be causing the problem, and if the hood is on in the right direction, assuming you use a lens hood. I shoot at 24 often with a polarizer and don't get vignetting.

Your description of the issue is clear - no need to post a picture. Here are some step-up rings:

I use a B+W CPL 77mm on my 24-70 Nikkor 2.8 without any problem. There may be something else going on. Good idea not to stack with a UV tho. Do you use a lens hood? If so, I suggest you try it without the hood on and see if that helps.

The lens hood mounts to the body of the Nikkor 24-70, not to the filter ring. Makes no difference whether filters (one or multiple) are installed whether the hood interferes or not. And the front of the lens moves forward with respect to the hood when it is zoomed to the wider focal lengths, further eliminating any interference from the hood.

Also, I have used both thin and thick single filters with no vignetting. This almost certainly comes from stacking filters, which has already been noted as unnecessary.

You should never stack screw-on filters because vignetting will be worse. Consider Breakthrough Photography's excellent CPL, which is very thin. That being said, I get occasional vignetting on D850 images and it is really no big deal to crop slightly. This is only an issue when there is sky or other light contrast area in the composition.

The OP stated he removed the UV filter, so wasn't stacking, which made me think there might be another cause.i don't know Nikon. Is that a lens that might have some vignetting?

You will need to use an adapter and go at least two sizes bigger for a filter. The same thin will happen even on a Canon 70-200 at 70mm when you use the 77mm screw in filter... you are basically shading the corners, and not getting a negative affect from the filter.

The wider the lens. the larger the CPL will need to be. A Canon 11-24mm requires a 186mm filter for an example on the extreme.

Stacking filters will amplify the problem.

An adapter for a larger diameter filter is one way to go. I've done that. But you wrote that you couldn't find one. For an ultra-wide Canon zoom I bought a set of thin filers through B + H. They work fine. Maybe keep looking for an appropriate step-up ring; I see someone posted a link. (And as others have written, don't stack filters.)

as I wrote, I don't stack filters. I can't turn the polarizer if I have the lens hood on. I can see the fall off in the corners through the viewfinder. I'll try the step rings and larger filter, thanks for the source information

Not trying to argue, but I just now tried it on a blue sky, shooting Canon full frame with an RF24-105 at 24, 77mm thread, with a 77mm Nikon CP, no sign of vignetting even at full mag. I must be missing something?

My 18-200 with the "proper" size filter on top of a skylight starts vignetting below about 35mm.
Yup, larger filter and a skinny stepping ring or remove the skylight.

I used a step up ring and 82mm filter on my Nikon 24-70 just to avoid the vignetting problem. I have since sold it and bought the Sigma 24-70mm f2.8 ART lens which takes the 82mm filter naturally with no vignetting.
