Nikon D400 rumors are back

Nasim Mansurov posted a new article on his blog regarding the mythical Nikon D400 camera. According to his source, who initially predicted the D400 announcement last year, the camera is supposed to be out around September this year:

"Apparently, the Nikon D400 has been pushed back at least twice now for several reasons. First, Nikon had some serious trouble with the supply chain when the floods devastated its Thailand plants. Most of the DX equipment was manufactured there (and many parts for the DX cameras and lenses were supplied by smaller companies in Thailand, which were severely impacted as well), so Nikon had to quickly move high-demand items off to other plants.

Nikon was on schedule for an early D400 announcement in 2012/2013 time frame, but it pulled the plug and decided to focus on the D7100 instead (and the current focus is to push as many D7100 sales as possible). It turns out that the camera went through several iterations and the earlier features did not fly with the upper management of the company."

As of today, I have not received a single reliable piece of information indicating that the D400 even exists. In my 2013 predictions, I mentioned that the 7000 and D300 product lines could merge. After the D7100 announcement we have been getting conflicting reports from Nikon in terms of the future of the high-end DX camera line.

More rumors on D400

………Nikon knows that the D400 has to deliver a large buffer with huge processing power in order to accommodate 24 MP files. Apparently, the current EXPEED 3 processor used on the D7100/D800/D4 is not capable of handling that much bandwidth, so Nikon engineers have been working on a new generation EXPEED 4 processor for the D400. This also means that the movie features on the D400 will be stronger, up to 60p in HD will be possible. Third, the 51-point AF system used on the pro cameras (and now on the D7100) is quite old, despite the fact that it got a slight boost with the introduction of the “Advanced Multi-CAM 3500FX” on the D800 and the D4. Nikon is apparently also working on a better and more advanced AF system, which is planned together with the D400 release (this explains why Nikon used the 51-point AF on the D7100). The Nikon D4s is also in the works with the same AF system, scheduled to be announced sometime in 2014.

New wave of Nikon announcements coming in August/September, D400 a possibility

Please note that even though this is the first time I am receiving any info on a potentials D400 camera, everything is still preliminary at that point and I would rate this at 60% probability for now.

"Nikon will soon announce a new NIKKOR AF-S DX 18–140mm f/3.5-5.6G ED VR lens........Obviously this new 18–140mm is intended to be sold as a kit lens. The big question is: kit lens to what? The D3200 and D5200 are pretty new for a replacement and I doubt this will be the kit lens for the D400. Stay tuned for more info. It has begun.

"....... I already mentioned that I expect three new Nikon DSLR cameras by the end of the year (the actual announcement could be in the first week of 2014 for the CES show): one full frame camera (probably D4x), one entry level DX model (probably D1000). The third camera is still not clear: it could be anything from a mirrorless to a SLT based or a retro design."
