Hi Jake, My knowledge regarding the features of the Nikon D 40 & D 60 is slender so I am just tossing out a word of caution. From you question I assume you are desirous to photograph through a microscope. Further you have a vision handicap and thus you want a computer monitor view to assist with composition and focus. Please clarify this understanding because to give advice we need to know your hearts desire. First let’s address the microscope only. If my understanding is flawed, disregard. When photographing through the microscope, there are three basic lines of attack. 1. Prime Focus - The camera lens is dismounted and replaced with an adapter tube. The microscope’s eyepiece is removed. The adapter tube is void of lenses (hollow tube) it replaces the microscope’s eyepiece. The image seen by the camera is a projected image stemming from the microscope’s objective lens (only). Magnification is low to moderate. Quality is high. 2. Projection Focus - A more elaborate adapter tube is used. It replaces the camera lens. It contains the microscope’s eyepiece. The image produced by the microscopes objective is further magnified by the eyepiece. A highly magnified view is projected into the camera. Quality is high – magnification is high. 3. Afocal Method – An adapter is purchased or fabricated that clamps the camera with it’s normal lens mounted, to the eyepiece of the microscope. The camera lens is positioned square with the microscope and the lens and eyepiece are almost touching. Due to the weight of the assembly the mount and clamp must be well-built and counter-balanced. Quality is moderate – magnification can be high. Easiest method as camera automation is intact regarding focus etc and through-the-lens exposure. Both Nikon models, for auto focus are dependent on focusing motors built-in to the lens barrel of Nikon type AF-S and AF-I lenses. Up to date D-60’s feature an electronic rangefinder to help with manual focus using the AF-S and AF-I lenses. Perhaps you will clarify your needs and maybe someone will advise as to the needed accessories and/or camera models. Alan Marcus (marginal technical gobbledygook)

I will give it a try. I have a Meiji stereo microscope and had a Nikon FM3a mounted to it. My health has went down hill, and I can no longer use this set up. Thus I am going with a digital SLR attached to the eye peace. That way I can sit with out pain and look at the back of the camera using the LCD and see what I am looking at. If my eyes get worse, then I would like to be able to attach the camera to a screen to blow up what I am looking at. I don't know if these cameras will allow this. I also want to be able to use my old lenses on the digitalis.

Jake, it seems to me that you might benefit from one of the so-called "live view" model DSLRs - where you can watch precisely what the imager chip is seeing before you take the shot. With that in mind, perhaps the D90 would be a better option, presuming you could tether it to a computer/monitor. Since I have the older D200 I cannot tell you offhand if it's possible to tether the D90 to a computer, but it might be worth investigating.

Nikon has a program "Camera Control Pro" that might work for you (http://www.nikonusa.com/pdf/manuals/software/ccp_en.pdf). Contact Nikon for more information.
