PM sent.

I'll leave the Nikon scanner lens here for another week (until January 10), and then move it to eBay. I will consider reasonable offers.

If anyone has an extra copy they would consider selling, please contact me.

I have to confess that several years ago, one early but memorable morning, I fumbled a Mitutoyo 10x objective when I was screwing it into position. It fell through my fingers just a short distance to the counter top, and suffered no visible marks on the surface of the glass or barrel. However, the i...

The specs for this scanner are amazing, too good to be true of course, 5300 ppi, 60mm scan area, APO corrected, 8 element lens. I would recommend the lens if you can find one of these scanners for a good price. They have been discontinued a couple of years ago and were sold under 4 different labels...

Wow, 16-image pixel shift technology! 240Mp!! If it has focus bracketing I'd sell my Panasonic S1R. Wow is right! Even without focus bracketing (which would be very nice, but I haven't seen it mentioned in any of the announcements), it would provide over 100Mp pixel shift images in APS-C crop mode,...

I routinely measure the voltage whenever I pick up old Vivitar 283 units, and then I tag them with the value. Most have measured around 9V, but I tested a couple that were well above that. Here's a site that has a schematic, and some suggestions for lowering the triggering voltage, but I've never fo...
