All Tests were done using a Nikon D200 camera
on a Super Polaris mount. No guiding corrections were done.
Move the cursor over the table to see images taken with different
lenses, f-stops and exposure times. It may take a while for
all images to load - please be patient!
Some images have been taken on different dates. Do not use
the overall brightness or color of the image as a criteria
for lens quality as both has been changed by processing.
1) was not properly
focused
2) field curvature is
visible
3) chromatic aberration
is visible
4) Image was processed in Iris, bad
focus
5) The corner image is actually upper
left, not lower left
