I've not done much portrait work, and I have a question about portrait lenses.
Is the 'desirable' focal length of ~85mm to get a slightly flattened perspective, in order to de-emphasise features on peoples faces etc? Or is it to allow a good photographer to subject distance? Or both? Just curious about the ideal portrait lens on a *istD. Obviously the FOV crop factor of 1.5 means that a 50mm lens has the same field of view as a 75mm lens, but, still being 50mm focal length has the same perspective on any camera. If the perspective was the main concern here, then still having an 85mm lens would be ideal, but then the FOV would be a lot tighter and might necessitate a lot larger distance to the subject.
