Thanks for responding .
I have the prints and I was most impressed. So impressed in fact, that I have, subsequently, had two (of Eucalyptus flowers) enlarged to 8"x12" and framed to hang on the wall in my house, and they look very good (to my eye, at least) .
This last weekend I put the 6T on the end of a Pentax-M 4.5/80-200 zoom (on an Asahi Pentax MX) and used up another two rolls.
Can't wait for the prints to return!
