Wetpixel member Jordi Chias has posted images taken with the INON UFL-MR130 EFS60 Underwater Micro Semi-Fisheye Relay Lens (let’s find a new name for the lens, please!) adapted to a Nikon D300 and old 60mm AF macro lens. The adapter was machined by Jose Sanchez at Saga Dive, which means that it will probably make its way to distributors at some point.
Chias says that the adapted lens works pretty well, but that there is some corner softness. Also, the port “needs to be very well machined to align both lenses and avoid vignetting.”
