Hi Jon,

Microscope shooting can be tricky. I'm still working it out for my 
setup. One thing I have found, which might help, is that setups that 
work well for film sometimes don't for digital. I suspect, though it is 
only a suspicion at this time, is that the greater reflectivity of the 
silicon sensor causes internal reflections in the microscope optical 
path. Sometimes it actually seems easier to use a compact digital rather 
than an SLR.

I really wouldn't have thought that Canon's do better macros than 
Nikon's, if that is what you are saying, even though I am a Canon user 
myself. It just may be that for a variety of reasons the people whose 
work you are seeing who are better at their craft happen to be Canon 
users. I get to play with Canon's, Nikon's, Sony, Pentax, etc and, in 
reality, they are really much of a muchness with differences in user 
interface and handling that make individuals prefer one over the other.

The Sigma's are nice macro lenses. This pics in this article:

were taken with the Sigma 70mm macro.

Cheers,

Wayne
