Nikon Z7 (2018)
The Nikon Z7 was announced in August 2018 alongside the Z6. It was Nikon's first full-frame mirrorless camera built around the new Z mount. The mount is a big change: a large 55mm inner diameter with a short 16mm flange distance. It signaled Nikon's long-term commitment to mirrorless over the F-mount DSLR line. At launch, the body listed at $3,399.95, or $3,999.95 with the 24-70mm f/4 kit lens.
The sensor is a 45.7-megapixel FX-format CMOS (35.9 x 23.9mm) paired with the EXPEED 6 processor. Native ISO runs 64-25,600 and expands to 32-102,400. The 493-point hybrid phase-detect/contrast-detect AF system covers roughly 90% of the frame, with sensitivity down to -4 EV. Stabilization is a 5-axis sensor-shift system rated up to 5.0 stops. Continuous shooting tops out at 9 fps.
The electronic viewfinder is a 0.5-inch unit with 3.69 million dots and 0.8x magnification. The rear monitor is a 3.2-inch tilting touchscreen with 2.1 million dots. Video tops out at 4K UHD (3840 x 2160) at up to 30p, with N-Log and HDR (HLG) output supported. The Z7 records to a single XQD card slot. Nikon addressed that with the dual-slot Z7II in 2020. The body is weather-sealed magnesium alloy and weighs approximately 675g (B&H Photo) or 1 lb 7.9 oz (Nikon USA) with battery and card. It runs on the EN-EL15b battery, rated at roughly 330 shots per CIPA standards. There is no built-in flash. Sync speed is 1/200 sec via the hot shoe.
The Z7 sat above the 24.5-megapixel Z6 in Nikon's initial mirrorless lineup, aimed squarely at the Sony α7R III. The sources available to the Archive document no long-term reliability data, common failure patterns or repair notes.
