Leica L39 to Sony E-Mount adapter by Kajashey

Last crawled date: 3 years, 5 months ago

An adapter for using the very old L39 or M39×26tpi Leica rangefinder lenses on a Sony E-mount camera.
Disclaimer: Use at your own risk. This is a freebie from the internet. No warranty. 3D printed lens adapters are very imperfect. Do not trust this to hold your expensive vintage Leica lens. Don't trust it to hold your grandfather's Leica lens. It may look precise but there is a lot of guesswork and just eyeballing it that went into the construction of this.
The all metal adapters are inexpensive and more accurate. This is to try out a lens in a carpeted area while that adapter is in the mail. This is to play with cheap Russian lenses that are L39 mount.
Doesn't focus at infinity? It might not quite do it for you. Try closing the lens up to ƒ/8 - that's pretty good for landscape.
Update: I updated the project and added threads because I'm comfortable modeling them now. This should be a fine lens adapter.
