Ruth's sister L39-NEX Camera Lens Adapter Ring internal power cable

SKU CH-KS2B-QA3W3

Adapts L39 and M39 screw-mount lenses to Sony NEX and A7-series E-mount bodies

  • Adapts L39 M39 LTM lenses to Sony NEX E-mount bodies
  • Enables use of vintage screw-mount glass on modern mirrorless cameras
  • Precision metal construction ensures secure lens-to-sensor alignment
  • Simple screw-on design requires no tools for installation

L39-NEX Lens Mount Adapter

This adapter connects L39 and M39 screw-mount lenses to Sony E-mount cameras including the NEX-3, NEX-5, A7, A7R and A7II. It provides a mechanical link without electronic contacts so aperture and focus remain manual. The ring is built for photographers who want to use vintage rangefinder glass on modern mirrorless bodies.

Manual operation limits automated exposure modes

Because the adapter carries no electrical pins the camera cannot control aperture or record lens metadata. Metering must be done with stop-down or manual modes and autofocus is unavailable. Buyers who need electronic communication or automatic diaphragm control will find this adapter does not meet those requirements.

Questions about this item

Should I choose the L39-NEX adapter for M39 or LTM lenses?

The ring accepts both M39 and LTM screw-mount lenses, so a single adapter covers either thread type.

What does the 39 mm mount diameter mean when I attach it to my Sony NEX or A7 camera?

It matches the standard 39 mm screw thread on your lens, giving a secure mechanical fit without changing the flange distance.
