The automatic NOVOFLEX Reverse Adapters EOS-RETRO and NEX-RETRO open up the world of extreme close-up photography with outstanding quality for owners of Canon EOS and Sony E-Mount wide-angle or zoom lenses.
The NOVOFLEX automatic reverse adapters let you reverse mount the lens on the camera. The ring transfers all control functions.
Example: With a Canon EOS 28-105 mm zoom lens in reverse position, you get an image ratio of 1:7 with a focal length of 105 mm from 1:7 to 2.8:1 at 28 mm.
This is a wider setting range than is possible with a macro lens.
The NOVOFLEX automatic reverse adapters are supplied with a standard 58 mm filter diameter. Stepping rings are available for other filter sizes.
