K&F M39 Lenses to Sony NEX E Mount Camera Adapter

The K&F M39 to Sony NEX E-Mount Adapter allows Leica M39 mount lenses to be used on Sony E-mount mirrorless cameras, featuring durable brass and aluminum construction, manual operation, and support for infinity focus.

The K&F M39 Lenses to Sony NEX E Mount Camera Adapter enables photographers to mount Leica M39 lenses on Sony E-mount mirrorless cameras, combining classic lens optics with modern digital performance. Compatible with a broad range of Sony NEX and Alpha cameras—including NEX-3/5/6/7 series, a3000/a5000/a6000 series, and full-frame a7, a7S, and a9 models (metal mount required for some a7 series cameras)—this adapter ensures a precise, stable, and secure connection. Constructed from high-quality brass and aluminum, it offers durability and long-lasting performance. Fully manual, it allows direct control over focus and aperture while supporting infinity focus. For heavier medium-format lenses, using a tripod or telephoto support bracket is recommended to maintain proper balance. The adapter is ideal for photographers looking to leverage vintage M39 lenses on Sony E-mount cameras.
