#RCA camera
Well, I spent many long and pleasant years as a high-end professional
commercial photographer, and I made it a habit to keep up with such minutae
as lensmounts. Unfortunately, my knowledge is getting old and dated, but
it do come in handy now and again. The lens you want is as short a focal
length as possibe while still maintaining flat field. On 35mm cameras,
that's probly one of the "macro" lenses. I use Canons, and theirs is 55mm
(mine is ancient!). Nikon is 50mm, I think.
The focal length will be a problem, as you'll be in superclose mode on the
video camera. I'm going to figure all this out hands-on but haven't had time
yet. I get most acceptable results with my DigiView as is.
Oddly, when i bought the thing, I had visions of installing my outrageously
sharp and expensive enlarging lenses on the thing (they fit the Cthread enough
to work). Unfortunately, they have no helical for focusing, though. Well,
live and learn.
