Nikon patent application 20130182173 is for combining/stacking a dedicated AF and imaging sensors without losing any light (in theory):
“The idea is simple: RGB color filter array does not use roughly 2/3 of the light in each pixel, why not use the lost light by a complementary-colored organic AF sensor stacked on top on the regular Bayer-pattern sensor.”
From the patent application:
The new Phottix Mitros TTL flash for Nikon is now shipping to retailers. The US price is set to $299.99. More details, features, specifications and promo video after the break:
Today’s guest post on the Nikon F-mount to NEX Lens Turbo focal reducer adapter is by Ainga:
To begin this post, I will say that I was highly skeptical of the quality of the optics from an unknown glass company from China called Zongyi, a.k.a. Mitakon. I was intrigued with the thought of transforming my NEX to a full frame camera without waiting a year for the NEX 9, I decided to give the Lens Turbo a try.
First off, the Lens Turbo is a focal reducer. The function of this adapter is to reduce the image projected by a full frame lenses to fit within the area of an APS-C size sensor; effectively eliminating the 1.5x or 1.6x crop factor. To say the least, wide angle lenses will stay wide angle with the angle of view comparable of a full frame 35mm camera.
Secondly, the light gathering capability of the lens will be enhanced by approximately one stop. The Nikkor 35mm F2D with the Lens Turbo have the light gathering power and the DOF of a 1.4 lens. Freaking magic.
Some online commentators claimed that the Len Turbo is a copy or a knockoff of a more expensive Speedbooster. I am quite sure that this is untrue, as the reduction ratio of two FRs is different, with the Lens Turbo coming in at x0.726 versus the SpeedBooster at. x0.71. That is suggestive of a completely optical formula used in the Lens Turbo.
Full disclosure: I DO NOT have any personal or commercial relationship with the makers of the products mentioned. I am only doing an impartial report with the inclusion of my personal observations with a copy of the Lens Turbo purchased on eBay with personal funds.
The samples are shot with the Nikon 35mm F2 AF and the Nikon 105mm F2.5 AI on the Sony NEX 7 at F2 to F4 aperture. Minimal post processing WITHOUT changes in sharpness or clarity.

Nikon published several new articles discussing their future business plan. In a recent Q&A session, Makoto Kimura (President, Member of the Board) raised his concern on the increasing smart phone market share and shrinking compact camera market:
For the Imaging Company, it is crucial that we determine how best to adapt our strategies in response to market
changes, particularly in terms of new products and product lineups. The rapid penetration of smartphones is causing the compact digital camera market to shrink. Previously, cameras and smart devices were not direct competitors. However, in the current market structure in which these products are competing, we must examine closely the concepts on which our compact digital camera offerings should be based. Thus, when it comes to interchangeable lens-type digital cameras, we need to question our ability to offer truly innovative functions and performance.
In another interview from last week, Makoto Kimura said that Nikon “want to create a product that will change the concept of cameras”.
