Reverse Adapter NEX-RETRO


For owners of Sony E-Mount wide-angle or zoom lenses, the NEX-RETRO opens up the world of extreme close-up photography with outstanding quality.

The NEX-RETRO lets you mount the lens in reverse position on the camera. The ring transfers all control functions.

Image quality is the decisive factor. In case of a higher magnification than life size the reverse mounting of a lens results in a
remarkably better image quality in comparison to normal use. E.g., in case of the reverse mounting and a focal length of 45 mm an image scale of 2:1 can be reached by direct use of the adapter. Even greater image scales can be reached by using bellows. An image scale of 6:1 can be achieved with a focal length of 35 mm in combination with our BALPRO 1 bellow with full extension. The combination of the NEX-RETRO with our universal bellows units of the BALPRO or CASTBAL-series will form a full fledged automatic bellows for the Sony E-Mount system.

The NEX-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 NEX-RETRO.
