## Long description

The Massa lens adapter SB782 enables mounting M42 screw-mount lenses onto Sony Alpha mirrorless cameras. This mechanical adapter provides a solid physical connection and correct flange spacing to allow infinity focus with compatible M42 lenses. It preserves manual aperture and focus control of the attached lens and is designed for photographers who want to use legacy M42 glass on modern Sony Alpha bodies for manual, creative shooting.
Advantages
The adapter is fully mechanical and does not contain electronic contacts, ensuring a durable and simple connection between M42 lenses and Sony Alpha camera bodies. Its precision-machined construction maintains reliable flange distance for accurate focusing, and the lightweight design keeps the combined lens-camera balance manageable. By retaining full manual control over aperture and focus, the adapter supports vintage optics that lack electronic communication.
Suitable for
Photographers who want to use vintage M42 lenses on Sony Alpha mirrorless cameras
Portrait and street photographers seeking the character of legacy glass
Macro, landscape, and creative manual-focus work with M42 lenses
Key specifications
Mount conversion: M42 screw mount to Sony Alpha (E-mount)
Construction: mechanical, no electronic contacts
Material: precision-machined metal alloy
Finish: matte or anodized surface to reduce reflections
Compatibility: supports manual aperture and focus of M42 lenses on Sony Alpha mirrorless bodies
Color: typically black
Weight: lightweight design for balanced handling
How to use
Attach the adapter to the Sony Alpha camera by aligning and securing the adapter to the camera mount until it clicks into place. Thread the M42 lens into the adapter’s screw mount until it is firmly seated, taking care not to cross-thread. Set the camera to manual or aperture-priority mode and use manual focus and aperture control on the lens. Verify infinity focus and adjust focus manually through the electronic viewfinder or live view as needed.
Usage recommendations
Use the adapter with a tripod or steady support when working with heavy vintage lenses to reduce strain on the camera mount. When focusing at infinity, confirm focus on live view at maximum magnification. Because the adapter is mechanical and does not transmit EXIF or autofocus data, enable focus aids in the camera (focus peaking, magnification) to improve manual focusing accuracy.
