Mike, Thanks very much for the information and I'm sure many on this list will benefit from this, most of all myself. I also use a Nikon 105mm Macro with my Nikon 801s but my eyesight has deteriorated. I used to use 'manual' focussing and I didn't have a problem, now I cannot and have to rely on 'auto.' I'm a lazy photographer and just use the dedicated SB20 flash but the good news is that I have a couple of 'slave' units which I will dig out and give it a go. I agree Vinny's information on photography is easy to follow. http://www.geocities.com/NapaValley/5491/index.html Many thanks and happy 'flashig' Helen ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
