Dear Scott,

I'd argue that a hardware auto-focus solution is essential.  We do a 
huge amount of such imaging and without AF it would be much more 
difficult. Olympus/Nikon and Zeiss offers such a system for their 
microscopes, but you can buy also a dedicated system (several 
possibilities).

Cheers    Gabor
