There is no doubt that camera companies are increasingly moving into the mirrorless realm, but that does not mean DSLRs are totally done for. Fans of Nikon's DSLRs will be happy to hear that the wildly popular D750 is due to get an update fairly soon.
The D750 proved to be a popular workhorse for a lot of photographers, combining a great full frame sensor with a respectable continuous shooting rate and good autofocus at an affordable price point, making it a very versatile camera that excelled in lots of different shooting scenarios. However, it has been over five years since the camera was first announced, and it is well due for an update. Thankfully, it seems that update is likely on its way soon, as Nikon Rumors is reporting that the announcement of the D780 is scheduled for the beginning of CES, likely January 7 or so.
Specs include a 24-megapixel BSI sensor, articulated touchscreen, faster continuous rate, 4K at 30p, dual card slots, and more. Altogether, it looks to be a quite capable and particularly well-rounded body that should definitely please a lot of Nikon DSLR shooters who would prefer to stick with their DSLR camera and lens libraries for the time being.
