Nikon 1 Nikkor 70-300mm f/4-5.6 Patent

The hottest news at the moment is about a patent for a 70-300mm f/4-5.6 native N1 super-telephoto lens. It has a radically different (more advanced) design than the 70-300mm full frame Nikkor: 20 vs. 17 elements, 13 vs. 12 groups, 6 ED and 3 fluorite elements vs. “only” 2 ED elements. The following photo of a mock-up at the Nikon 1 announcement back in September 2011 could be the N1 70-300mm.

The native N1 70-300mm, should it ever come to market, will have an equivalent focal length of 189-810mm and an equiv. aperture range of f/10.8-15.12. Sure, it’s nothing to write home about in terms of DOF, but this kind of reach doesn’t come cheap for any format. Judging by the 6 ED and 3 fluorite elements this one won’t be cheap either, but it should have excellent image quality straight from max. aperture, especially at the long end, where other 70-300mm telephotos struggle. And it must, since stopping down to f/8 would result in diffraction taking its toll.

Advantages of such a native lens compared to the already available 70-300mm FF Nikkor would be the smaller size and reduced weight because of no need for the FT-1 adapter and smaller rear elements needed for the smaller 1″ image circle, and full AF support (area AF with AF-C and target tracking instead of just center point AF).

This lens would open entirely new possibilities for N1 users, which is why I’m hoping it didn’t fall pray to Nikon’s “rethinking” of the N1 system. I also hope that those ED and fluorite elements don’t make it insanely expensive (>1000 bucks).
