Sony a7 III Firmware Update 3.0: Boosts Eye AF Capabilities and Adds Interval Shooting for Time Lapse.
A new version of the 24.2-megapixel Exmor R™ CMOS sensor, now featuring a back-illuminated structure, is combined with the latest BIONZ X™ image processing engine and front-end LSI, and this combination achieves a data readout speed that is two times faster and a data processing capability that is 1.8 times higher.
The a7 III is equipped with a refined image processing system that allows it to capture full 24.2MP images at up to 10 fps with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent shooting. The a7 III can also shoot continuously at up to 8 fps in live view mode with minimal lag in the viewfinder or LCD screen. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.
The a7 III features a world-class autofocus system comprised of 693 focal-plane phase-detection AF points that cover approximately 93% of the image area, 425 contrast AF points
The 5-axis in-body SteadyShot™ image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in an image stabilization system at 5-step shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills, and for A-mount lenses9 attached via a mount adapter.
Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW images can be recorded to one card while JPEG images are recorded to the other. It is also possible to record stills and movies to different cards. Relay recording automatically switches to the second card when the first card is full. Data can be copied between cards while in the camera, for convenient back-up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is required.
The a7 III is exceptionally capable as a video camera, offering 4K (3840x2160 pixels) video recording across the full width of the full-frame image sensor. In video mode, the a7 III uses full pixel readout without pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce
The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the NP-FW50 W-series battery giving the a7 III the longest7 rated battery life of any Mirrorless camera at 710 shots per
Both compressed and uncompressed 14-bit RAW4 format are supported. The 14-bit digital signal from the image sensor’s analog to digital (AD) converter is processed in 16-bit form by the front-end LSI and BIONZ X™ image processor before being output as 14-bit RAW data. The result is smoother, more natural gradations that contribute to higher overall image quality. The enhanced BIONZ X image processing LSI makes 14-bit RAW4 output available even when shooting in silent5 or continuous mode.
The a7 III boasts a high-luminance 2.359 million dots EVF (XGA OLED) Tru-Finder™ which reproduces the finest
