Re: SEM follow-on question

We have several posts now saying that SEM images are orthographic
projections.  So I think probably a flat circle lying on the tilt 
table is a flat circle when viewed in the stereo viewer.  But what 
does it mean when you've taken a picture with the equivalent of an 
infinite focal length lens and then viewed it with a finite-length 
ocular?  What sort(s) of distortion(s) result?
