I have a couple of these adapters still around, but I had them made for the 95PN in order to mount it in 1:2 configuration. For the 105PN, or the 95PN in 2:1 configuration, I highly recommend Raf's M45-M42 adapter:Chris S. wrote:If a Printing Nikkor 105mm is not already configured for DSLR use, making it so is not difficult. Start with Rafcamera's eBay part 142382208066, add a 52mm-thread extension tube, then a reversing ring for your camera mount.mawyatt wrote:Do you know of any of the PN 105 A that are already configured for DSLR use . . . ?
Back in 2012, before the Rafcamera adapter was available, Ray Parkhurst helped a few of us get custom adapters made by his machinist. These adapters were (and still are) very nice, and are the equivalent of the Rafcamera adapter part plus a length of 52mm reversing ring, though as a single piece. If Ray has any of these left, or if his machinist cares to make more, I'd highly recommend them. But with the Rafcamera part readily available off-the-shelf (and given the good quality of Rafcamera items), going with the Rafcamera part seems like an easy and very workable solution.

There is a trick to make this work...the front trim ring, which has m43 filter threads, is removable, and reveals an M45 thread that allows the Raf adapter to attach.
Remember, the 105PN is optically symmetrical, so it doesn't matter which way you mount it. I've been using mine with the Raf adapter and it works great.
