using filters on wide angle/fish eye lens

yeocolin · 1st June 2003

Hi,
I've heard of buying specially thin filters and circular polarisers when using wide angle or fish eye lens (from 16mm up to 19mm kind of wide angles) to prevent vignetting.

What kind of filters/polarisers should I look out for? Is there some special term for such specially thin filters/polarisers? Thanks.

rear drop-in type gelatin filters?

Yes, there are such filters. For example, Hoya's series of "Ultra" filters are designed for wide angle lenses. Quoted from Hoya website:

"Filters in this series use our new ULTRA thin rings which, like the Super PL-CIR filter, are designed primarily to avoid vignetting problems which occur with wide angle lenses. The ULTRA series filters use rings just 3mm in thickness, except for the hybrid UV/Polariser which has a 5mm rotating ring."

See Hoya's site for more details:

Hope that helps.
