[Rollei] Off topic: filters for ZI Nettar

[Matthew Phillips <mlphilli >]

I recently picked up a Zeiss Ikon Nettar, with Novar 4.5 lens and Vario
shutter. The images aren't in the same league as those from my Rolleis, but
the optical nature of the little Nettar (crisp central image with
pronounced edge fall-off) has a charm of its own - especially nice for a
nostalgic 'old family-snapshot feel'.

The Novar lens doesn't appear ro be threaded for filters. Any clue as to
what size push-on adaptor will fit?

Cheers,

M.Phillips
