## Long description

The Lens Adapter B.I.G. 421308 enables mounting of M42 screw‑mount lenses on Sony E‑mount cameras. Constructed from black metallic materials, the adapter provides a secure mechanical connection between older M42 optics and modern Sony mirrorless bodies, allowing photographers to expand lens options and apply vintage glass characteristics such as distinct bokeh and color rendering on contemporary camera bodies.
Advantages
The adapter's robust metallic construction offers durability and a stable connection that resists play and misalignment. Its precise mechanical fit maintains correct flange distance for reliable focus performance at the photographer's intended focus settings. The neutral design preserves the original optical characteristics of M42 lenses without electronic communication, ensuring compatibility with a wide range of manual lenses and simple operation.
Suitable for
 Photographers who want to use vintage M42 lenses on Sony E‑mount mirrorless cameras
 Portrait, street and creative photography using manual-focus glass
 Videographers seeking unique bokeh and color rendering from classic lenses
 Collectors and enthusiasts adapting legacy lenses for digital use
Key specifications
 Mount conversion: M42 (screw) to Sony E (bayonet)
 Material: metallic construction with black finish
 Finish: black, metallic appearance
 Compatibility: mechanical only — retains manual aperture and focus control of attached lenses
 Form factor: compact, low‑profile adapter
How to use
Attach the adapter to the M42 lens by screwing it onto the lens's M42 thread until secure, then align the adapter to the Sony E‑mount on your camera and rotate until it locks into place. Operate the lens using manual focus and aperture controls; the adapter does not transmit electronic signals, so camera exposure modes and focus aids should be selected accordingly. Confirm secure seating before use and re‑check whenever changing lenses to avoid accidental detachment.
Usage recommendations
For best results, use manual exposure or aperture‑priority modes and enable focus peaking or magnification on the camera to assist with manual focusing. Handle the adapter and vintage lenses carefully to protect mechanical threads and mount surfaces, and keep contacts and mating surfaces clean to ensure consistent fit and performance.
