Fabre Sterescopic microscope
The Nikon's "Fabre Photo EX" optical system features 20-times magnification, and the actual field of view is 11mm in diameter. The shooting magnification varies depending on the connected camera, but it will be about 45 to 66 times when a Nikon DX format camera (A4-size print) is used.
The Fabre device has been on the press last year.
A video taken with the device is visible here.
