Nikon's first full-frame mirrorless, introducing the Z-mount system with a 24.5MP sensor.
The Nikon Z6 was announced in August 2018 alongside the Z7 as the higher-speed, lower-resolution body at the launch of Nikon's Z-mount mirrorless system. The 24.5MP full-frame sensor and 12fps burst positioned it as the all-around Z-mount body — resolution for general stills, speed for action, and oversampled 4K video. The original Z6 uses a single XQD card slot; the Z6 II (2020) added a second slot (XQD/CFexpress Type B), improved burst buffer, and additional video features. This master covers the first-generation Z6.
The 24.5MP full-frame BSI CMOS sensor pairs with the EXPEED 6 processor. The 273 on-chip phase-detection points cover 90% of the frame for reliable subject tracking in stills and video modes. Burst shooting runs at 12fps with continuous AF/AE. 4K video records at up to 30fps from an oversampled full-frame readout. The 5-axis IBIS is built in. Dust and moisture sealing is provided throughout the body. Battery life approximately 310 shots using the EN-EL15b, body weight approximately 675g with battery and card, single XQD card slot — XQD cards and readers add to total system cost.
The Z6's practical strengths at launch were the 12fps burst with 90% PDAF coverage, oversampled 4K/30fps video, and 5-axis IBIS in a full-frame mirrorless body. The single XQD card slot is the most significant practical limitation: XQD is a less common and more expensive format than SD, and XQD readers are not standard equipment. For photographers who already have XQD infrastructure from Nikon DSLRs, the slot choice is non-disruptive; for others, the card and reader investment is a consideration.
On the used market the Z6 is widely available at accessible prices. The Z6 II provides dual card slots, improved burst buffer, and updated video specs at a moderate premium — the recommended upgrade for professional use requiring card redundancy. Condition checks: IBIS operation, the single XQD slot contacts, weather sealing at the body seams, and EN-EL15b battery health — the EN-EL15 and EN-EL15a from Nikon DSLRs are also compatible for regular (non-USB-C) charging. Compatible with all Nikon Z-mount lenses and F-mount lenses via the FTZ adapter.
