Rollei H-1 filter...what is it?

Todd Frederick , Mar 28, 2000; 12:49 a.m.

I have a Rollei H-1 filter in a Bay I mount that I would like to use with my Autocord if appropriate. What kind of filter is that? Looking directly through it, it is clear, but, at an angle to the light, on both front and back surfaces, it has a strong magenta tint. Any info on this?

Sounds like a multicoated Haze 1 filter. All my camera lenses and all of my Hoya multicoated filters look green, amber, or magenta when viewed at an angle, but it's just the coating.

It's a UV filter. No exposure increase is required.

This is NOT an UV, it is the equivalent of a 81A

In Rollei filters, HI is NOT a uv. The UV eliminates ultra violet light and has 1.5x exposure factor. HI absorbs ultra violet in colour material, reduces blue cast, with no increase of exposure. All other Rollei colour filters in the Rollei bay one are based on Deca-Mire system and are labeled R1-R16 and B1-B16.

The different colours off the surfaces is the coating on the filter.
