I've had no luck trying to locate information, adapters or lenses for miniature cameras with NF mount lenses.
The NF designation isn't related to the thread style, but instead is a miniature version of of C or CS mounts, which instead of being 25mm, the NF is 16mm diameter (or maybe a 16.5mm).
I wasn't able to locate the specifications of the NF mount threads. I'm not sure what thread pitches are commonly used on camera/optical equipment (although 32 tpi is a rough guesstimate).
The miniature video cameras I'm interested in are the SONY XC versions, which use the NF mount and utilize a 1/3" CCD imaging device.
Adapters exist to adapt the larger C mount series lenses to NF, but my preference is to use miniature lenses with the mini cameras.
I expect to use aluminum for fabrication (or possibly brass) and I suppose that anodizing is probably about the only option for coatings for aluminum fittings.
Much of the threading for optical parts is very near a shoulder and a narrow cutting tool would need to be used, maybe a ground HSS cutoff tool for external threads.
I would most likely approach the threading operation with a hand crank since the threads on optical fittings are generally only a few revolutions.
Please share any info related to threading practices, specifications or fabrication of small threaded components that could be applied to optical equipment.
Any guidance would be appreciated.
Another area of interest is adapting various optical components' focal length. I've found online info about the various camera lens optical elements (vague, Wikipedia), but would like to have any recommendations for references to optical mechanics. I have a Selsi/Edmond diopter gauge, but the minimum lens size it can measure is about 20mm diameter.
