Just a quick & dirty test with my new beauty (the lens Smile!) - not the best lighting conditions and 1/50 sec handheld ...

I have that lens - without MM coupling.
I likeed that lens long time - since I did some close-up work with different iris settings - and some light points in the background: The bokeh "circles" with iris at 2.0 to 4.0 were jagged :-/

I have seen that phenomenon before - and you easily can see the reason whenn looking at the iris ... it simply doesn't close as a nice circle but has those jagged interlinks. I suppose you can call that a defect ...

I heard from others who has the same. Up to now I think that is the normal behavior of the iris at this lens - or do you think the iris is used to much and the mechanics is now to loose - could be a possibility.

That's exactly what's different between AE and MM versions of this lens as well as some others (Sonnar 135/2.8 being another one). I had an AE version of this lens with notable 'ninja star' shaped aperture at f/2 and 2.8; later on I changed it to an MM version, which produces a regular, 8-sided polygonal bokeh. It escapes me why Zeiss wouldn't use curved aperture blades in this one like they did in the 180/2.8 Sonnar or even 85/2.8 Sonnar.

The story of blades is a curious one.
Early German lenses had a lot of them. Sometimes even numbers like 20 blades. Then for cost reasons, Japanese makers started to make lenses with less and less blades. Followed, in a short time, by European makers, including the big names of Leica and Zeiss.
But then, in the 90s, a new mania boomed, born in Japan, that of the "bokeh". The number of lenses started again to be considered a value and not an expendable feature. And so Japanese makers started to raise again the number of blades in the new lenses, leaving behind the European makers, who are still reluctant to reintroduce many blades in their lenses.
There is something ironic in all this Very Happy

Regarding the ninja star, it's not the devil as many say.
True, in the early-intermediate apertures (say f/2.8 to f/4), they look like cogs. But try to stop down more. At f/5.6 and beyond, they look rounder and more pleasing than the brutal hexagons of straight blades.
So, as always, you win some, and you lose some Smile

The ninja star blades are not that bad; many consider them to be a Zeiss trademark anyway. However, I don't care much about the rendering of a f/1.4 lens at f/5.6 or smaller Smile I have a beutiful dwarfish Zeiss Sonnar 85/2.8 which I'll take for stopped down performance any day over the huge beast of Planar.
