[Histonet] Imaging Histological Specimens

[Geoff McAuliffe]

Hi Hector:

    For photography during surgery a much longer lens is needed to 
provide longer working distance and avoid the problems you mentioned. 
For the F series Nikons (F4, F5) the 180 mm lens was often used. I don't 
know if that lens will fit the D series cameras, call NikonUSA and ask 
them. Perhaps they make a longer macro lens for the D series.
    If you want more than life size magnification of rat hearts, etc. 
you will need to extend the lens with a bellows or extension tubes. 
Again, call NikonUSA and tell them what you want to do.
