Me too, and an older MD 58mm f1.4 as well.
Did some experiental images not long after I bought the 40D with the MD 50mm f1.7 and it has nice wide fov but I did notice some Spherical Aberrations (?) on bright starts in the edges operated wide open.
Seems even more striking with the MD 58mm f1.4. Might be a consequence of the optics in the adapter ?
Been a long time since I used the old XD5 for astroimaging, so I can't remember if I saw aberrations with these lenses on negatives.
I wonder if that is correctable in Photoshop ? (Not got that yet).
Or in Paint Shop ? (Have it).
