The Nikon D5600 is a modest upgrade to a solid entry-level DSLR. The camera was first announced with only availability in Japan, but announced U.S. availability will begin in January of 2017.
The Nikon D5600 takes much of what consumers like about the D5500, including a 24 megapixel APS-C sensor with the optical low pass filter removed for enhanced detail and clarity. The D5600 also sports an Expeed 4 processor and 5 fps burst speed. Nikon's second-cheapest APS-C DSLR still retains the tilting touchscreen as well.
So what's new? The D5600 includes Bluetooth capability. Unlike Wi-fi, Bluetooth doesn't cause a big power drain, so it can be left on all the time. That allows Bluetooth to enable to send automatic back-ups to Nikon Image Space, a cloud back-up, though that feature is currently limited to reduced resolution files. The Bluetooth will send full resolution files to a smart device manually, though is limited to JPEGs. The D5600 also gets about 100 more shots per charge over the D5500.
The D5600 also adds the time lapse feature introduced in the D7000 series, but previously wasn't available on the more budget-friendly options. The time lapse feature allows users to select intervals to shoot photos at, then automatically merges the images into a video.
The Nikon D5500 is a solid beginners and enthusiast camera -- the D5600 builds on that with enhanced connectivity. While the update isn't huge, the D5600 should build on the success of the D5500 with similar image quality but with the added perk of Bluetooth and time lapses. Since the image sensor and procecssor remains the same, opting for the older D5500 at a lower price isn't a bad idea, as long as you don't mind the lack of Bluetooth and time lapses. The D5600 continues to offer a solid set of features for the price point. Canon's Rebel T6i is similarly priced, but still has the optical low pass filter, slower video frame rates at 30 fps, fewer autofocus points and nealy half the battery life.
