The Japanese Photography blog, Egami has discovered a Nikon patent for interchangeable sensor technology. Click here to read the original article in Japanese. It is important to point out the vast majority of patents never make it out of the laboratories. With Canon and Nikon both working on Medium Format sensors and technology, 2014 may be proving to be an interesting year for product announcements.
Personally, I think both companies are misguided in pursuing the Medium Format arena. Canon is far behind in their 'meaningful' product announcement and should concentrate on their core competency. Nikon is trying not to be left behind on the MF train. Read my latest post on this topic. Meanwhile, the photographic community is waiting with bated breathe for some real announcements.
