Featuring
a back-illuminated design, the newly designed full-frame 61MP Exmor R
CMOS sensor offers a mixture of incredible resolution with high clarity,
low noise, and a wide 15-stop dynamic range. The sensor's structure
promotes impressive image quality and a copper wiring layer dramatically
improves data transmission speed for creating 14-bit, high-resolution
61MP stills with a native sensitivity range from ISO 100-32000, which
can be further expanded to ISO 50-102400.
The
BIONZ X engine's high-speed image processing enables the fast continuous
shooting, 4K video recording, and advanced AF tracking. The quick
processing also helps to reduce rolling shutter and other motion
distortions for the clean rendering of moving subjects.
In terms of shooting speeds, the sensor and processor enable up to 10
fps shooting, at full resolution, for up to 68 consecutive frames, with
full-time AF/AE.
This
unique compositing mode allows you to achieve even greater resolution
than the 61MP sensor affords. Working in conjunction with the
sensor-shift image stabilization, this mode shifts the sensor while
making 16 consecutive exposures to acquire approximately
240.8MP of information for greater color accuracy and detail than
possible with a single exposure, along with an impressive image size of
19,008 x 12,672 pixels. These files can then be merged during
post-production by using the Sony Imaging software suite.
An updated Fast Hybrid AF system now employs a combination of 567
phase-detection points, which cover approximately 99.7% of the height
and 74% of the width of the frame, along with 425 contrast-detection
areas for reliable and quick autofocus and subject tracking performance.
This focusing system also achieves especially quick speed and reliable
tracking, as well as enhanced low-light focusing response down to -3 EV.
The apt focus system also lends itself to a variety of focusing functions for refined accuracy:
-
Lock-on AF maintains focus on moving subjects through the use of a
configurable frame that is set over the desired moving subject
-
Expand Flexible Spot employs neighboring focus points to retain focus on
moving subjects even if the originally selected point loses focus
-
Eye AF can be used to base focus on recognized human subjects' eyes for
portraits and is available in both AF-S and AF-C modes and for both
stills and video. Eye AF can be used when photographing animal subjects,
too, with any focusing mode when shooting stills.
-
The Focus Magnifier function can be used for critical focus when homing in on minute subject details
-
The rear touchscreen can be used for Touch Focus control and a Touchpad
Focus Control mode lets you use the rear screen intuitively while
keeping your eye on the viewfinder
