distortion with 150mm

[Raven Garrow]

Is it true that when using a 150mm lens in 4x5 format, doing a closeup shot (not macro), that distortion can occur?

[Bob Salomon]

Distortion - straight lines are not straight. Foreshortining - items closer to the lens are larger than they should be.

Which are you referring to?

Foreshortening is normal and the shorter the lens the more pronounced it is.
