Polarizing filter for HCD 28mm

[cerett]

Any recommendations for a polarizing filter that will avoid vignetting. Thank you.

It depends on which camera it is used on. I used a 95mm Heliopan circular polarizer on the H4D40 and H3D50 cameras successfully. The 28mm lens vignettes without a filter on the H4D60. You might also consider a Lee 4" square glass polarizing filter as an option.
