If anyone in this forum is in the UK and uses the Russian Kiev 80 Hasselblad clone, I've just spotted a lens for it on sale in London.
Tair-33, 300mm f4.5 with Kiev 80 mount for 6x6cm SLR. Huge heavy bugger and seems to have quite a lot of internal dust.
If anyone actually wants this, it's the Cash Converters shop in Kentish Town road - it doesn't seem to be on their web site. They had no idea what it was at all, just look in their display case for a Russian Lens and a price a bit over £100. I suspect it will be there for some time...
