P&S Compact camera lens conversion adaptor to M39 LTM with RF coupling

<ul> <li>Update - Dec - 28 - 2021 After one and a half years doing those conversions and many successful lenses I'm now pretty confident with this design.<br/> The M36 thread that act as the focus helical has been redesigned now with a dual start 1.5mm pitch, providing a more secure and "nicer" feel to the focus.<br/> But makes harder to print, you will need to calibrate your machine and also spent some time making small adjust and some eventual scraping.</li> </ul> <hr/> <p>(original)<br/> I have been working on the design of these adapters for a few weeks already, and now I would like to share what I consider the best version so far.</p> <p>This model provides for the possibility of link with the camera rangefinder.<br/> This should work with many compact lenses but I have no way to make available a specific part for each one, so this is a starting point and there is a template and you just need to design the cavity to accommodate your lens and the rest should work.</p> <p>I've tested it with film Leicas and Canon 7 and Sony mirrorless.<br/> I'll leave a link for post on my blog (PT-BR so use a translator) where I share more details and photos.

A small negative value such -0.1 of "horizontal expansion" (CURA) can help a lot.</p> <p>*Use a very small amount of glue to fix parts such the focus stopper and RF ramp after you have all calibrated.</p> <p>*A little scraping and sandpaper may be necessary, as well as trimming some parts like the ramp of the rangefinder which will vary according to the design.</p> </p></p></p> Category: Camera
