Leica L39 to Sony E-Mount adapter

thingiverse

Adapter for using old Leica rangefinder lenses on Sony E-mount camera. Gentle cone screws into lens, no M39 threads. Ensure lens is straight and controls are where you want them. Use at your own risk. No warranty. 3D printed adapters are imperfect. Don't trust to hold expensive vintage Leica or grandfather's lens. It may look precise but there's guesswork and eyeballing in its construction. All metal adapters are inexpensive and more accurate. Try this adapter in a carpeted area while waiting for an all-metal one to arrive. Use with cheap Russian lenses in L39 mount. Lens might not focus at infinity. Close it down to f/8 for good landscape shots.
