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.
