Nikon just announced on its global page that it is indeed working on the successor to the D4S. The release states that the company is in the process of 'developing' the Nikon D5 which will be its new flagship FX-format DSLR. We don't have any other details on pricing or release date at this point. Nikon also said it is working on a couple of new accessories like the Wireless Transmitter WT-6 and the Speedlight SB-5000, which should be announced alongside the D5.
The timing of this news points to a possible announcement during CES 2016. Even though we don't have any detailed specifications or features about the Nikon D5, it's not too difficult to guess what we can expect from the new model. Nikon will most likely retire the ageing 16.2-megapixel sensor for a larger one in order to support 4K video. We can also expect support for more autofocus points, faster burst mode and perhaps a higher native ISO sensitivity.
The Nikon D5 will most likely retire the D4S, which was introduced last February in India
as a refresh of the original D4
. The current flagship features an improved Expeed 4 image processor over the older Expeed 3, a higher native ISO sensitivity of 25,600, 11fps burst mode, full-HD video recording at 60fps and a bigger price tag.
Speaking of the price, we expect the new camera to cost anywhere north of Rs. 4,00,000 (approximately $6,000) for the body only, considering the current D4S retails for around this price. We'll hopefully get more details next month as we inch closer to CES 2016.
