I have been quite curious, when I first found some pictures of this "little monster" - but could not stop myself from looking, where I could buy it - especially after I found out that there is a version for my PENTAX K mount...

So I ordererd one an when today the small package arrived, I shurely tried it out immediately - which has been a real new way of taking photos to me:

3-dimensional manual focusing is not that common and neither is the manual change of the magnetic aperture rings...

But the results are - at least interesting - if not to say exciting...
