Fringer NF-FX AF-C Tracking Test with Nikon AF-S 500mmF4G VR on Fujifilm X-S10

Fringer has just tested and optimized the performance of the Nikon AF-S 500mmF4 G VR using the new Nikon NF-FX smart AF adapter on a Fujifilm X-S10.

Fringer has also optimized Nikon AF-S 600/4G VR. Unfortunately, it doesn’t work as stable as 500/4G on X mount due to the power supply limitation. The next firmware release, i.e. v1.10, will include supports for these lenses as well as some of the other big primes.

You can see the AF demo video as well as the full list of supported lenses below.

Nikon F mount to Fujifilm X mount Smart AF Adapter New Features and Coming Soon

Fringer Nikon F to Fujifilm X Smar AF Adapter

Press Release

New feature of Fringer NF-FX adapter: LaCA correction

Fringer NF-FX (Nikon F mount to Fujifilm X mount) smart adapter will be released soon. Today we’d like to introduce an interesting feature of the adapter, i.e. LaCA correction.

LaCA, stands for lateral chromatic aberration, is resulting from a difference of image scale at different wavelength of red, green and blue light. LaCA causes colored fringes at high contrast edges of the image.

When we shoot RAW, LaCA can be easily removed by post processing. However, a key feature of Fujifilm cameras is their film simulation. In other words, we usually use the jpeg files directly out of the camera with few post processing. When using native X mount lenses, there is no problem since Fujifilm cameras will correct all the LaCA automatically. But when using adapted lenses, LaCA become a problem.

Fringer NF-FX has a built-in LaCA correction profile data base for all the lenses that have been tested and optimized (see this list). When shooting jpegs, the adapter will provide the LaCA correction profile of current lens to the camera automatically. The latter will use that profile to correct LaCA when generating jpeg pictures. Finally, user get a jpeg photo directly out of the camera which is LaCA free.

Please see the following example.
