[photo-3d] Loupes, making the best stereo slide viewer

[Jon Golden <3dman@xxxxxxxxxxx>]

Lincoln and Robert,


A pair of the de Wijs 50mm lenses, as used in the COMBY viewer, will cover
not only vertical and horizontal full frame 24 x 36mm....but will almost
cover 40 x 40mm superslide (the most minute clipping at the corners).

Prices are less than half of what you are describing below...but contact me
off list since this is not a selling forum.

Take a look at what Grant Campos (sorry dont have his email or URL
available, as I am on a remote via laptop) did with a pair of the deWijs
45mm lenses in a Kodaslide II viewer. NOTE:  45mm will not cover full frame
but provides a bit more magnification, optimized for  Euro and Realist
formats images.

We carry both sizes of lenses.
