I own a Canon 24-70 f/4 IS and just purchased the 16-35 f/4 IS. The circular polarizer that I currently own does not work with my lens caps. Can anyone recommend a good CP that will accommodate a Canon lens cap? Thanks in advance for your help!

Doug - the thin polarizers will not accommodate a standard lens cap. If you get a thicker one that does accommodate a cap then you will end up with slight vignetting. If that's acceptable to you then any polarizer that specs that it is double threaded will work. I still use thin polarizers and don't cap my lenses when in use. When not in use they are in neoprene pouches and if the polarizer is mounted it goes in face down bare - not ideal but the little pop on caps that come with the thin filters get lost the first day...

Doug, Singh Ray sells thin plastic Push On Caps that will fit over most polarizers. They come in various sizes from 52mm to 82mm. They may be what you are looking for. I have two of them both sized at 77mm that fit snugly enough for them to be effective.

I have the same problem because I have a screw in collapsible rubber lens hood attached to the polarizer (so the polarizer is easier to spin) that won't accept a front cap. I keep soft cotton fabric in the bottom of neoprene pouches and store the assembled lens, polarizer, & rubber hood face down as well. Because the hood is collapsible, I can change it's length so it is compatible with different focal length lenses.
Don't recall ever seeing any reviews / tests of any polarizer.

A step up ring can also be used instead of the thin polarizer, the thins can be very thin and fragile.

Doug, Joe's suggestion above re: the push caps would be something to look into for the polarizer you already have.

This is the polarizer I have for the 16-35. I read up a bit, and it seemed like it was the thinnest to still accept regular caps and also to allow me to screw in another filter (say a variable ND) when I wanted.

Thanks for the advice everyone. I'm going to try a Lenscoat Hoodie with my current circular polarizer. If I don't like that solution, I'll try Greg's polarizer recommendation.

Hoya makes an EVO Anti-static polarizer in a thin mount that still allows lens caps to grip the edge. The filter is thin enough to avoid any vignetting but still deep enough for a standard lens cap. It is a very high grade filter equal to some of the best on the market. Here it is mounted on a Zeiss-Sony 16-35 f/4 with cap attached. Sony caps work identically to Canon caps:

I have been testing the Hoya HD CPL, B+W XS Pro and the new Benro CPL-HD Slim. All of them are slim, have front threads for the lens cap and work perfect.

Any of them does not vignette on my 16-35 mm and are of very optical high quality.

For some years I worked with the B+W Slim CPL without threads and I hate their useless lens cover. I will never use one again.
