According to sources Nikon is set to release the Nikon 1 J2 during Photokina this year. The Nikon 1 J2 will be the replacement for the flagship Nikon 1 J1 compact system camera and will come with a bunch of new accessories as well as a underwater case making it ideal to be used for subaquatic photography.
There are still no much info available on the Nikon 1 J2 camera but we expect sensor to remain the same with some minor tweaks in the JPG engine.
Coupled with the new Nikon 1 J2 camera there will also be a new kit zoom that will be pocket sized being likely based in what Nikon showcased at 2011 PDN PhotoPlus show in New York.
We will post up more information once available. At this stage we are eager as you to get more info in the upcoming Nikon 1 cameras.
