I have complemented my article with a panorama that was outputted
with PTGui Pro then processed with Pano2VR and you might download a
set of the three source images (RAW):
The chromatic aberration isn't really more pregnant than for our
other fisheyes but it is somewhat differently colored. It's still

The geometry is more than nice and pleasing as it allows to have a
much higher (+16%) panorama native resolution than the Nikkor and
better IQ at the nadir and zenith of a 3 or 4-shot panorama.
I still have to test for flare and glare.
Image sharpness and contrast seem to be quite constant from full
aperture till f/16. The claimed f/3.5 value may be a little over-
