Ok before I go any further than this- please do not feel you HAVE TO mail
me off-list to tell me I am right, dead wrong or otherwise - I am a little
off set by the number of people on this mailing list the that felt it was
important to mail me directly or CC me with their  response.

So here is my last response to this issue-

Does pincushion or barrel distortion occur when copying a flat object with
a camera lens ? Yes

Does a flatbed scanner eliminate pincushion or barrel distortion- Yes

BUT be aware even the best flatbed scanners can create their distortion
of their own - Drum scanners are the way to go but at a price of 15 to 40
thousand- its unlikely you will find someone to loan you the use of one for
free.

Do I think that it is significant or even perceptible with a normal or mild
telephoto focal length for copying a document less than 20 x 24?  NO,  not
really- but that is my opinion, of course

At that format with my 10

Last point  - if you have a camera and a tripod or can borrow one
