#RCA camera
I think our best lenses were for his old Miranda. He could focus that
thing on a postage stamp and make a full-size slide from it. Used it to
make slides for classroom presentations, mostly. He could take a picture
of any little diagram he could find, then project it for the class to see.
Very, very old now – but quite good. I don't know the brand of the lenses
themselves.
Several yearsago, he took pictures of very faded old family pictures and
made them sharp and new (with various filters). Quite a few relatives
were extremely happy with the pictures he gave as Christmas presents that
year!
