Hi, Chuck,

What exactly do you mean "perspective distortion"? Are you referring to geometric distortion?

There are many wide-angle lenses with quite modest geometric distortion. It costs, of course.

So, in order to duplicate the perspective
of a normal lens with the 1.6 crop factor, one has to settle for a
fair bit of distortion. Such is not the case for a medium format
photographer using an 80mm lens to achieve the same perspective.

Of course it is not focal length,. or field of view, that influences perspective, only distance to the subject. Of course, we may need to use an appropriate focal length lens to include the desired materials in the shot once we decide where we must shoot from to get the desired perspective.

Best regards,

Doug
