Well done.

There's a story about the chromatic aberation. The 400mm f/6.3 telephoto lens that I used is an old 42mm Screw Mount lens from the 1970's (thereabouts) and you can actually buy EOS adapters for these screw-fit lenses.
Using this lens a decade or two ago I had a lot of success (images were good, field was flat, no aberrations) taking 35mm SLR Film images with it (piggyback style), so it seemed like it would be a good thing to try out with the EOS SLR.
But to my surprise the EOS shows a lot of aberrations and violet fringing that was not apparent in any of the film images I did with the same lens.
Here is an example of exactly what I am talking about.

DIGITAL SLR http://www.skylab.com.au/pmsa/ngc3372d.html
I still haven't convinced myself I know why the Digital SLR shows all the aberations when the Film SLR does not.
