Reversing Adapter L-Mount

For owners of L-Mount (Leica, Panasonic, Sigma) wide-angle or zoom lenses, the LET-RETRO opens up the world of extreme close-up photography with outstanding quality. The LET-RETRO lets you mount the lens in reverse position on the camera. The ring transfers all control functions. This is a wider setting range than is possible with a macro lens. The LET-RETRO is supplied standard with a 58 mm filter diameter. Stepping rings are available for other filter sizes. In order to protect the sensitive rear lens element we supply a high quality, multi-layered protection filter coming with the LET-RETRO. Technical specifications: Size: 75 mm (2.95?)
