Kipon introduces reducer to fit Nikon F and Leica R lenses to Micro Four Thirds bodies

13 Aug

Japanese lens and accessory maker Kipon has introduced a pair of focal length reducers that allow users to mount Nikon F and Leica R lenses to Micro Four Thirds cameras to give a 1.4x crop factor. The company says that the Kipon Baveyes NIK-m4/3 0.7x and Baveyes L/R-m4/3 0.7x reducers make a 50mm lens designed for full-frame systems act as a 70mm equivalent once the focal length doubling effect of the Micro Four Thirds system is taken into account. Kipon also claims that the reducer makes the mounted lenses a stop faster too.

Without the lenses in the reducer a 50mm Nikkor lens mounted on a Micro Four Thirds camera would behave as a 100mm due to the smaller size of the system’s sensors, so the wide-angle elements in the adapters reduce the apparent crop factor applied to the adapted lens. The company gives an example of a 35mm lens mounted via the adapter producing the angle of view one would expect from a 49mm lens on a full-frame body.

The price of the adapters has only been released in Japanese Yen, and is quoted as ¥23,000 plus tax, which is approximately $ 230/£180.

Kipon to launch reducer to mount medium format lenses on full frame cameras

18 Dec

Chinese lens manufacturer Kipon has announced that next year it will make available a reducing adapter that’s designed to allow medium format lenses to fit on full frame cameras. The adapter will have a magnification factor of 0.7x which it says will both widen the effective focal length of the lens in use and widen its effective aperture. 

The first adapter will be designed to mount Hasselblad lenses on Sony E-mount cameras, but the company says it is working on other mounts for a wider range of both lenses and host cameras. 

The lenses in the adapter channel the light from the exit element to create a tighter covering circle. This means light that would otherwise fall outside the sensor area is directed to land on it to be recorded.

When a 50mm Hasselblad lens is mounted on a current Hasselblad digital body it produces a similar image area to a 35mm lens on a full-frame camera. That calculation though is a factor of the sensor size of the Hasselblad camera, and the same lens would not deliver that apparent angle of view were it mounted on a full frame camera or in front of the 6x6cm film frames Hasselblad lenses were designed to be used with. 

The 0.7x magnification of the Kipon adapter has the effect of canceling out the crop factor, turning that 50mm Hasselblad lens back into a 35mm-equivalent on a full-frame camera.

The adapter will have to be very good quality to make the most of the resolution of Hasselblad lenses, otherwise the exercise will be a bit pointless. It is expected to retail for $ 415 when it becomes available in February.
