Hi Harvey,
Looks reasonably sharp in the center - are you satisfied or dissatisfied with the performance of this equipment, or have any particular question about it?
I have seen good results using the 500D close-up with various lenses. It's my understanding that it allows fairly close focus, with the main limitation being that the focus range distance is somewhat restricted.
Another way to accomplish the same thing is with the use of Extension Tubes. There is a little loss of light, but it does work quite well.
BTW - I love your signature
I've been trying to come up with some other variants, but I'm not sure they're ready for prime-time!
