Got that lens, made a few tests. What do you think? Crappy?

Not crappy at all, just different... :D

The bokeh seems to come from a lens with very wide aperture.

Or from one of these Russian old lenses ?

Klaus. These are stunning images. The flowers are wide open I guess? The toad is f=4 or f=5.6?

German means Zeiss or Leica? or is it but a GDR "crappy lens"...?

Not crappy, but perverse. It is certainly no APO lens (lots of CA on the toad pic too), but "enjoyable" and "perfect" are two moderately overlapping concepts. Now, what's that lens?

The circular out-of-focus highlights in the fourth photo make me think this is a mirror lens, but I don't know what it might be.  I did a casual internet search. but didn't find any German mirror lenses.  I'm confused..no reason to make an f/2 mirror lens, since size and weight is usually the driving consideration for those.

I know now, I guess this is Meyer Optics. Isn't it? They have these 15 blade aperture dream bokeh

If I am not wrong, Hugo Meyer made only one lens with maximum aperture f/2 : the elusive 5cm f/2 Kino-plasma. Not sure you can find one now. if so, make sure you have $10 00 (minimum) available on your bank account...

There's now a ''purchase fever'' for these lenses : the Trioplan 100mm f/2.8 doubled his price in less than 2 years. :P

Ok. 2.0 then it could be a Leitaxed R lens?
