Features: Lens adapter for Leica M rangefinder LM-E mount lens to compatible for Sony E-mount mirrorless cameras, such as for A7 A7SII A7R A7II A6300 A6500 NEX series etc. All manual operation like manual focus/AE metering/IS, support infinite focus. Built in macro focusing helicoid support macro focus on any lens. Precise workmanship: perfectly combine the camera with lens, no gap or wiggling. All-metal construction with chrome plated brass mount, ensure solid connection and durability. Usage: 1. This is a manual adapter, so lens functions that rely on electronic communication with the camera body (auto focus, AE metering, image stabilization, etc.) will be disrupted. 2. Set your exposure manually or use your camera's Aperture Priority (stop-down) mode for metering. 3. If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
