j I have a camera that will focus down to 1 cm. I have used it
j to do a feature article for Corel. It is a Ricoh RDC-2E. It
j is old and only 768x576 but it takes excellent photos close
j up. I don't know if you could find one now but if you really
j want one I might sell you mine.

I know you are asking for 2.5 cm and my Nikon 3200 will not
quite do it but 4 cm is not bad.
