Pentacon 2.8 / 135mm

The Pentacon 2.8/135 are at the origin Meyer Optik Görlitz Orestor. They can be found later with bayonet mount as Prakticar 2.8/135mm.

Pentacon Auto 2.8/135mm delivered with the Zenit Automat received in May, 2009.

I already had the bayonet version, here is the M42 model (I already had one, found by one of my customers'; the rear optical group is missing, some people are able to lose anything!).

Pentacon 2.8/135mm delivered with the Praktica LB2 in November 2009.

And the older version, uncoupled aperture.
