The Z6 III is Nikon's first camera to to feature a partially stacked sensor design for faster scans and readouts than its predecessor. The design also reduces rolling shutter and noise levels when working at the top end of the ISO range. Additionally, this sensor design unlocks many of the flagship-level features in the camera, like faster autofocus, a smoother EVF experience, faster continuous shooting speeds, and higher frame rates when shooting video.
Complementing the sensor is the EXPEED 7 processing engine, found in the top-of-the-line Z8 and Z9 mirrorless cameras an which offers speeds approximately 10x faster than the Z6II. This engine works in conjunction with the partially-stacked sensor design to realize impressively fast AF speeds, burst shooting rates, a high buffer capacity, fluid video performance, and quick all-around handling.
Top continuous shooting speeds of 20 fps when shooting in raw, up to 60 fps when shooting in full-frame JPEG, and 120 fps when shooting JPEGs using a DX crop, with all rates supporting full AF/AE performance. Able to buffer over 1000 images in a burst when using the electronic shutter, meaning image sequences can be recorded for approximately 50 seconds continuously.
Pre-Release Capture at up to 120 fps helps make decisive moment shots easier by recording frames in a burst for up a second prior to actually releasing the shutter. When this feature is activated, burst shooting will commence when the shutter is half-pressed and the buffer will retain up to 3 seconds' worth of frames prior to fully pressing the shutter. Electronic shutter affords a top shutter speed of 1/16,000 sec for working in the brightest conditions with wider apertures.
Utilizing inherited algorithms and deep learning technology from the Z9, including sophisticated Subject Detection, the Z6 III can recognize a variety of distinct subject types, ranging from humans to animals to airplanes to bicycles. When working in Auto-Area AF, these subjects will automatically be detected, focused on, and tracked to ensure sharp focus when the subject is moving across the frame.
Eye-Detection AF, specifically, has been tuned for improved accuracy and refined recognition of eyes in the scene, regardless of how small or large they are within the image frame, and can also be used in conjunction with custom Wide-Area AF for different subject shapes and sizes.
