Lens Adapter Novoflex NEX/LER

The Novoflex NEX/LER lens adapter enables the use of Leica R lenses on Sony NEX (E‑mount) mirrorless cameras. Constructed with precision and a black finish, the adapter creates a rigid mechanical connection between Leica R optics and Sony bodies, preserving correct flange distance to allow proper focus range and maximize image quality from legacy lenses when mounted on modern mirrorless systems.

Advantages

The adapter provides reliable mechanical coupling and a durable exterior that resists wear. By maintaining the correct registration distance it enables accurate infinity focus and full use of manual aperture control on Leica R lenses. Its straightforward, compact design keeps lens-to-camera alignment stable and minimizes light leak or play when changing lenses during field use.

Suitable for

• Photographers who want to use Leica R lenses on Sony NEX/E‑mount mirrorless cameras
• Owners of Leica R glass seeking to extend the life and versatility of legacy lenses
• Manual-focus shooting, including landscape, portrait, and fine-art photography

Key specifications

• Mount type: Leica R mount (lens side) to Sony E mount (camera side)
• Material: metal construction with durable black finish
• Function: passive mechanical adapter, no electronic contacts
• Compatibility: supports manual focus and manual aperture control of mounted lenses
• Physical: compact and lightweight design for easy handling

How to use

Attach the adapter to the Leica R lens by aligning the lens mount marks and rotating until it locks. Then mount the combined lens and adapter onto the Sony NEX camera body by aligning the adapter’s E‑mount mark with the camera’s mount and rotating until it clicks into place. Use the camera in manual or aperture priority modes and focus manually on the lens focusing ring; adjust exposure and viewfinder or screen settings on the camera body as required. To remove, reverse the installation steps: unlock the adapter from the camera body, then detach the lens from the adapter.

Usage recommendations

For best optical results, enable focus magnification or focus peaking on the Sony NEX camera to assist with manual focusing. When using wide-angle Leica R lenses, check for potential vignetting or mechanical interference on certain camera models. Store the adapter and mounted lenses with caps fitted to prevent dust ingress and protect mounting surfaces.
