I've been building Numismatic Photography setups for folks for a while, and have devised a flexible platform that can serve a wide range of needs with many options. I custom make each setup to fit the needs of the user. You can view some of the setups on the Coin Community Coin Photography Forum. Do a search for posts by rmpsrpms and many of them contain info on the setups.
All versions are based on the Bausch & Lomb A-Stand, a small-footprint stand used for adjusting focus on Stereo/StereoZoom/MonoZoom Microscopes. I modify the stands to accept Bellows for taking Macro Photos of coins, and add a high quality lens and all necessary adapters. I can offer LED lighting as well so all you have to add is your camera and you're ready to go! I can even supply the camera if you wish.
The stands come in 3 versions:
1) Bellows-only units, or can be supplied as stand only for use with your bellows (these are called "Ichiban")
2) Convertible Stereo or StereoZoom Microscope / Bellows units (these are called "Nitoku")
3) Convertible MonoZoom Microscope / Bellows / Camera units (these are called "Santoku")
I can offer a wide range of high quality lenses for high resolution coin photos, both for whole-coin shots as well as detail shots for varieties. Higher magnification shots can be achieved with the MonoZoom Microscope attachment.
Pricing for the units ranges from <$200 for an Ichiban stand only to >$3000 for a Santoku with a Printing-Nikkor lens.
If you are interested, PM me with a few details about how you want to use the setup including the following:
A) What equipment do you have now such as camera, bellows, lenses, copy stands, etc
B) What denominations of coins do you want to photograph (Mostly Dollars, Mostly Cents, all US, etc)
C) Do you want to photograph varieties
D) Do you want the setup to include a Stereo Microscope or high power MonoZoom Microscope
E) Do you need a recommendation for camera for use on the bellows, or for me to include one with the setup
The example setup in this listing is a Nitoku with a StereoZoom3 Pod, 10x eyepieces, bellows, and Nikon 75mm El-Nikkor lens.
