The 85mm f/4 Zeiss Triotar is a very nice and cheap, albeit somehwat rare, lens in Contax RF mount. On my Kiev it's a match made in Eastern Europe (or heavens, depends who you ask).
The lens is flarey, but printing on a contrasty grade seems to hide the central flare spot that I saw on my contact sheet.
I didn't use a hood on this shot, and will now stick to using one.
