[Brightcolours]

Nice shot, Brightcolors. 

Although I can spot a Nisen bokeh in there and I suspect that the result isn't quite as impressive on pixel level.

 

However, yes, there are many lenses out there that can be downright awesome at a very low price (e.g. some of the Russian stuff)

The lens has horrible optics, Klaus. Not very sharp at all, no way to stop it down. Very smooth bokeh close-ish up, but at the edges that can go a bit haywire for some reason, very high CA and astigmatism/coma issues at the edges especially when focussing further away.  

 

And most probably more rare than a gold plated Meyer optics 100mm!
