Wide angle lenses made for digital backs work well, the defining issues are: The angle at which the light stikes the sensor and the resolution in line pairs. digital lenses have larger rear elements and as such the angle or incidence is more perpendicular and less apt to flare off of the surface of the sensor or the filter. The ability to resolve detail smaller than the pitch of the actual pixels on the array is necessary to prevent artifacting and lack of detail. This specification is around 50 line pairs per mm.
