I canceled the Walimex mirror test, BTW. The measured resolution was well below the minimum mark ...

does this mean the resolution is "far" beyond a 400/500mm-lens with a 1.4/2*converter ?

The base units seems to cost just under 2000EUR.
The individual extension modules should be around 200EUR or so.[/quote]
I searched and couldn't find a store that sells it. Can you please provide a link?

And which camera is used? And what makes that the aperture, with that focal length and f5.6 at 500mm?

According to EXIF, shot was made with a digital compact (Canon IXUS 300 HS), so it is diffraction after all.
Edit: sorry, my post overlapped with the BC's.
