These two frames compare the image quality of two fisheye lenses I use:
Fuji S1 - ISO 320 - WB: cloudy

Nikkor 8mm - f5.6 1/20 sec
this is an f2.8 lens seen on the table in the other shot

Sigma 8mm - f5.6 1/20 sec (not an EX lens)
this is the 8mm f4 MF lens, an f8 1/10 exposure is here

There is a discussion about using fisheye lenses on the panorama list comparing Coastal, Nikon, Peleng etc:
Comparing several different fisheye lenses including the Nikkor 8mm/2.8 and the earlier and later Sigma 8mm fisheyes - it seems the newer one is more even in its illumination wide open but less even when stopped down.
