Pentacon six TL
Pentacon six TL (1958-1990) Medium Format SLR
The Pentacon 6 is a medium format system camera, a SLR that takes 6×6 pictures on 120 film. It has been called an "SLR on steroids". Its predecessor was KW's Praktisix with which it shares the bayonet mount. The famed Carl Zeiss Jena plant made lenses for this Pentacon Six mount. The Soviet factory Arsenal made a closely related camera called Kiev 6 and later Kiev 60. (camerapedia.org)
I have the original receipt for this camera purchased in Moscow by original owner in 1979.
I purchased the metered prism recently.
The Biometar 2.8/120 Carl Zeiss Jena lens was purchased in Vienna this year at an amazing store: the Leicashop. I really like this lens.
