That is very interesting. Does the digital sensor record the shorter
light wavelengths? I thought they were filtered out similar to IR unless
the camera was converted to full spectrum. At any rate - some very cool
effects and interesting OOF areas.

The daisies look really sharp, though it's hard to be sure with a small
image.
It is a very sharp lens, but it's not particularly well corrected (ie.
it's not APO). You can see for yourself if you like in this full jpg
of a test shot I made this morning, file size around 7 MB:

Same setup as the daisies, stopped down to f/11. It has been sharpened
in Lightroom.
I didn't buy this lens for its sharpness, but it's a nice bonus. I
wanted the large aperture and transparency to shorter wavelengths than
the eye can see. The bokeh on full opening is amazing, and it renders
high-contrast gradients in a very peculiar way. That was particularly
visible when used with the 645D, so I'll be looking into options for
making a mount for that system too.
Btw, I made a GIF animation of the DOF from full opening to f/22, if
anyone's interested.
