Elias, while you can use a MF lens for the 35mm format, try to use a
35mm lens for MF, there are lot of adapters to use MF lenses on 35mm
but it's very difficult, almost impossible to find an adapter to use
a 35mm lens on a MF camera, these facts are telling us something.
MF lenses and 35mm lenses are designed to cover different frame sizes,
BTW MF lenses a bigger area and then you have that a MF lens on 35mm
film uses the central part only, the part with the highest optical
correction and without fall-off, in the other hand a 35mm lens for
35mm film needs to use the entire lens including the surfaces close to
the edges and the edges themselves appearing some residual optical
problems and fall-off, the problems and aberrations could only
increase for a bigger film format.
Using Rollei MF lenses for 35mm you only can obtain excelllent to
superb results with the 24x36mm format.-
