K&F Concept Contax G to Sony E Mount Adapter

The K&F Concept Contax G to Sony E-Mount Adapter enables the use of Contax G lenses on Sony E-mount mirrorless cameras, featuring a solid brass-and-aluminum build, manual operation, and support for infinity focus.

This adapter allows photographers to use premium Contax G mount lenses on Sony E-mount bodies. Compatible with a wide range of Sony NEX and Alpha cameras, it expands creative options by bringing classic Zeiss-designed optics to modern digital systems. Constructed from durable materials, it provides a secure fit and long-lasting performance. It is fully manual, requiring manual focus and aperture adjustment, and supports infinity focusing for maximum flexibility. For heavier lenses, using a telephoto support bracket or tripod is recommended to maintain balance.
