As a rule, lenses do not alter perspective. In general, any distortion seen in an image is due to the image being viewed from the wrong distance; view it too close and the perspective appears flat, view it from too far away and the perspective is exaggerated.
This can be proven optically by enlarging the center area of an image taken with a wide angle lens that corresponds with the same area photographed with a longer lens.
VIEWING DISTANCE
A comfortable viewing distance would be equal to a normal reading distance and can usually be calculated by measuring the diagonal of the print. The correct viewing distance however could be calculated by the focal length of the lens used multiplied by the magnification of the image.
