Ultra-Micro-Nikkor 55mm f2...Leica screw mount...figure out a Leica screw mount adapter for Canon EOS mount for close up small DOF photography, or something like a Sony NEX with appropriate adapter and 1:4 lens, for bitingly sharp flower stuff?

Here's a $140 (yikes) M42 focusing helicoid for the Nex.

http://cgi.ebay.com/21MM-FOCUS-STROKE-HELICOID-M42-SONY-E-MOUNT-TUBE-/320669609676?pt=Lens_Accessories&hash=item4aa965eecc#ht_1161wt_957



But this thing, and also buy a M42-to-Leica-39 stepdown ring for about $4, and you can probably focus any-Leica-thread-lens-over-44mm-focal-length on a Nex. A $6 dollar set of Gissin M42 extension tubes, 3 pieces totalling 49mm length, from Ebay, might also be relevant to the project.



The minimum length of this 21mm long focuser on the Nex brings you to about 18+21=39mm from the sensor plane, don't know if that's the flange-to-film distance you need or not.



This is not to say that you should mount the lens on a Nex. Am simply documenting the economics of doing so.
