 Hi Wayne,
It is not possible to use another lens on the 35/35 Roundshot camera
because the focal length of the lens determines the length of the film.
The calculation of  the length of the negative at 360° is approx.
focallenth x 6
example:
10mm lens = 10 x 6 = 60mm
35mm lens = 35 x 6 = 210mm
I  mean at a rotation camera the diameter of the drum inside would have
to be changed at another focal length, what means it should be smaller
for wideangle lens and bigger for a longfocal lens. 

Roundshot with 28mm was available, 5 pieces exist worldwide.

The only possibility now is the Roundshot Super 220,  where you have the
possibility to change the focal length, see the new catalogue:
