As some of you might remember, I bought one of the authentic Canon FD-EOS converters in hopes of using an FD 600mm f/4.5L that I bought at a particularly attractive price.
I had an opportunity to try it today, and the results, while generally satisfactory, make it clear that this is only a good combination, and not a magic bullet.
The first shot is for reference only, and was taken with a 50mm f/1.4 lens. This will give you some idea of my distance to the bus (remember the bus?).

This is the bus taken from the same spot. This is effectively a 982mm lens after you figure in the 1.26X TC and 1.3X crop factor.

This is probably the best train shot I got today, and it looks pretty good, too. At 100%, though, there's a bit of purple fringing, especially in high contrast areas.

This is always my standard test for sharpness. If I can read the fire extinguisher sign on the locomotive door, I feel I've done okay. This is a crop from the picture above, and you can see some of the purple fringing in this shot. It looks pretty gross here, but on a 13 X 19 print, it is hardly noticeable.

I'm generally happy, and there's no doubt this lens is a keeper, but I don't think I'll be taking the big white EF lenses off my wish list anytime soon. Besides, I've really grown fond of auto-exposure and autofocus. This lens is completely manual.
