Re: ATM (Fwd) Copier Lenses and mirrors

["Phillip Smith" <hapchap@bigpond.com>]

You have been unlucky, older
Photocopier's and Fax machines have a small lenses in them, they range from
15mm to 80mm in size, the most common size is 50mm in photocopiers (please
note:- it is very rare to find a copier lens bigger than 50mm). Modern
Photocopiers do not have lenses at all
go to a photocopy repair shop and ask if they have any, I did a week ago and
managed to get 4x35mm, 3x50mm and 1x80mm lenses
