Nikon's first full-frame mirrorless, introducing the Z-mount system with a 24.5MP sensor.
The Nikon Z6 launched in late 2018 as Nikon's first full-frame mirrorless camera, alongside the high-resolution Z7. With a 24.5MP BSI-CMOS sensor, 5-axis IBIS, and the new Z-mount, it positioned itself as the mirrorless equivalent of the D750. It was Nikon's answer to the Sony A7 III.
Key features include the 24.5MP BSI sensor with excellent dynamic range, 273-point hybrid AF, 5-axis IBIS, 12fps burst, 4K video, and a large 3.69M-dot EVF. The body is weather-sealed with excellent ergonomics inherited from Nikon's DSLR heritage. The single XQD card slot was controversial.
The Z6 is praised for outstanding image quality, excellent EVF, and comfortable handling. It is criticised for the single card slot, AF tracking that initially lagged Sony, and limited Z-mount lens selection at launch. The Z6 II addressed the card slot and AF concerns.
Very good value used as the Z6 II and Z6 III have superseded it. Check shutter count, IBIS operation, and the XQD card slot. The Z6 remains an excellent full-frame mirrorless body, especially for landscape and portrait photographers.
