Back on the days this was a projector lens and therefore it has no iris. It's constantly wide open at f/2.8
Less parts to break, if you ask me..
Recently I had a not so good experience with another Pentacon, the 135mm preset with 15 blades. After shooting 50 or 60 images all the aperture blades came out of place and ruined one hell of a lens that many call "the bokeh monster"
Gladly the Ebay seller promptly offered himself to support all the repair costs and I sent it back. Let's see how that will play out.
Sony a7 + Pentacon AV 80 --- ISO 500 --- f/2.8 --- 1/1250 sec
THAT SMALL GESTURE WILL MAKE A WHOLE LOT OF DIFFERENCE TO US!
