A hidden gem from East Germany (Web Pentacon Jena) - not many people know, this lens performs optically very well. Some Pentacon lens has horrible build quality and their optical performance is very mixed (ex. Pentacon 29mm). Fortunatelly this lens is different very capable performer and quality built too. The lens is quite uncommon, but not particularly rare. I am very happy owner of a beautiful copy, if you see any grap it and enjoy.

Decent lens , decent if not superlative quality ( build and optical both ) , CA can be a bit of problem on high contrast area if not stopping down ( at least 1.5 stop to 5.6 ) defocused background / foreground ( bokeh ) is certainly not its virtues. nice coverage, lightweight , made a pretty good lens for APS-C and 4/3 coverage. I recall it seems to work fine on the Sony FF, but I need to check , certainly not FF friendly with Canon DSLR though. On a Canon 1D series DSLR it made for a very nice grab shoot lens ( roughly that of a 40mm on film capture ) Read more
I own one in with Exakta mount and pre-set diaphragm. I?m really pleased with performance of that tiny lens. It?s very sharp and contrasty and in my case it totally outperforms its successor, a latter Meyer Orestegon / Pentacon 29/2.8.
