Although Nikon’s entry into the 4K world is delayed, the D7500 is nevertheless the first 4K-capable SLR camera under 1,500 euros. Mirrorless hybrid cameras are already available in almost all price categories from various manufacturers. In the case of the direct DSLR competitor Canon, there are 4K, however, currently only from the EOS 5D Mark 4 (RRP approximately 4.000 euros), while Nikon 4K already for a few months in the upscale DSLR market with the D500 (RRP approx. 2,300 euros) offering. In the DSLR-Profiklasse over 5,000 Euro (Canon 1DX as well as Nikon D5) 4K has also already arrived.
Both Canon and Nikon offer with their 4K-DSLR equipment only the read-out of gekroppter sensor ranges. Here is simply a “4K window” from the entire sensor area recorded, which usually significantly more for the photomodus holds.
As a result, in 4K shots can only be used an image cut out and the effective focal length of the optics is significantly restricted. For small-format full-size models like the Nikons D5 (for UVP approx. 6900 Euro) or the Canon 5D Mark 4 (RRP approx. 4.000 Euro) you are with the 4K window still in regions of an analog super35mm Filmausschnitt. In the case of APS-C models, the cut-out of the 4K window, on the other hand, usually ends up between the size of an MFT sensor and a 1-inch sensor. 4K cameras with such small sensor surfaces are, however, generally as mirrorless models much cheaper to buy.
More 4K features in the competition
The royal path is therefore the readout of all sensor pixels of a large area sensor and then the merging of these values into a 4K image. This process is referred to as over- or down-sampling and provides very clean detail and color separation when the sensor surface is fully utilized (when carefully calculated). In the competition field, this currently dominate all new Sony APS-C cameras (a6300 and a6500) as well as the no longer available Samsung NX1. The Panasonic GH5 also calculates its 4K image from the (almost) full sensor area.
Who does not renounce the mirror in the camera gets the competitors in this price class besides Oversampling additionally additional features such as moving sensors or 10 recording. Seen in this way, the D7500 is primarily of interest to users who find a mirror or optical viewfinder indispensable for taking photographs or who already have a large body of Nikon optics. Because with appearance (June 2017) is the Nikon D7500 for approx. 1.500 Euro currently the most favorable 4K-capable reflex camera.
