Info / Description:
Oreston / Pentacon 50/1.8 was first manufactured for the Exakta RTL-1000 in auto mount, and later in M42, M42 Electric, and later (until the late 80's) in Praktica B mount.
This lens has several interesting features, it can focus right down to 33 cm , good enough for most close up; lesser known is the fact that the lens has almost perfect symmetrical design very similar to the original Zeiss double Gauss Planar design (with thick cemented center groups) making it a very usable lens for reverse mount and bellows work. In fact it was remarked by many experienced in this lens that it performs excellently in the macro / close up range.

The photos show this lens has an f/22 minimum aperture.

My example of this lens has a larger s/n (perhaps more recent?) and has an f/16 minimum aperture. Also, mine lacks the zebra focusing ring and has far more travel at minimum focus. Dimensions of my example are 63/40 mm (d/l) at infinite focus; the length increases to 52 mm at minimum focus (0.33m).

Thanks for info! It was an error in the listing, this one is for f/22 min aperture version. Also added f/16 and f/16 electric versions.
