Sony Alpha a7R IIIA Digital Camera Body

A New Level of Image Quality

The Sony Alpha a7R IIIA Digital Camera is fully equipped with 42.4MP high-resolution, and back-illuminated Exmor R CMOS image sensor that utilizes a gapless on-chip lens design, with an anti-reflective coating on the surface of the sensor’s glass to dramatically improve the overall light collection efficiency. This results in high sensitivity with a wide dynamic range and low-noise performance.

Sony’s α7R IIIA features a new front-end LSI effectively doubling the readout speed of the image sensor. Compared to the A7R II the newly updated BIONZ X™ processing-engine helps to improve processing speed by approximately 1.8 times. With powerful components working together the camera is allowed to shoot at faster speeds with the impressive ISO range of 100 - 32000 and impressive 15-stop dynamic range while in low sensitivity settings. Overall these incredible capabilities ensure outstanding performance in all shooting conditions and settings.

This full-frame digital camera model is constructed without an optical low pass filter to ultimately maximize resolution. While still having the ability to output 14-bit RAW format, even while shooting in continuous or silent mode. Equipped with an innovative 5-axis optical image stabilization system that supports a high-resolution shooting capacity, and a 5.5 step shutter speed advantage, ultimately performing the world’s highest compensation performance. The new low-vibration shutter decreases overall vibration and image blur in all modes, including the high speed 10 fps shooting. There are also several advancements in color reproductions of skin tones' accuracy.

Depicting Scenes in Intimate Detail

Delivering high resolution and low noise, the image processing system has evolved throughout a wider ISO range. With enhanced technology, the A7R IIIA displays the mood of every scene maintaining the texture of details.

• 42.4MP full-frame Exmor R™ CMOS sensor - The Exmor R sensor’s back-illuminated, gapless on-chip lens design increases light sensitivity and provides a wide dynamic range, despite its high resolution of 42.4MP.
• Greatly enhanced image processing - A new front-end LSI and BIONZ X™ boost processing speed and are teamed with the Exmor R™ sensor to deliver up to 15-stop dynamic range at low ISO sensitivity for stills, enabling richer tonal expression.
• Wide standard ISO 100-32000 range - The standard ISO range has been extended to ISO 100-32000 (expandable to ISO 50-102400), and noise has been reduced by as much as a full stop in the mid sensitivity range.
• 14-bit RAW output for rich gradations - 14-bit RAW format output contains rich tonal information from highlights to shadows and is available even when shooting in silent or continuous mode.

Strong, Light, Reliable Design Takes you Further

High-resolution Quad-VGA OLED Tru-Finder provides natural, high-precision viewfinder image. The functional advantages of an EVF, such as high visibility in darkness and AF capability when using magnified display, is further enhanced for powerful shooting support. For even greater versatility, the α7R IIIA’s small, light body is robust and rigid enough for rugged use.

Seize Moments with Quick Precision

• Up to 10fps continuous shooting - Capture an instant action with continuous shooting of up to 10fps with AF/AE tracking. Huge data of 42.4MP imaging maintains high image quality that is advantageous for your creative trimming.
• Shoot continuously in absolute silence - This camera allows silent shooting at up to 10fps with AF/AE tracking. Silence is critical for shooting wildlife, when even slight noise can mean missing a chance at an ideal shot.

Dramatically Evolved AF Performance

AF performance is improved by inheriting the AF performance used in the α9 and applying it optimally, so once the α7R IIIA captures a wild animal that moves unpredictably, it won’t easily let it go.

• Comprehensive Fast Hybrid AF coverage - 399 phase-detection AF points covering approx. 68% of image area width and height plus 425 densely positioned contrast-detection AF points improve focus that might otherwise be unachievable.
• Up to 2x faster (approx.) AF response - Thanks to much more responsive, enhanced Fast Hybrid AF, AF speed is up to approximately two times faster under dim lighting conditions.
• AF tracking improved by approx. 2x - The AF algorithm inherited from the α9 accounts for two times more preciseAF tracking for continuous shooting, even of complex or sudden movement.
• 4D FOCUS - Conventional autofocus (AF) deals with space alone. 4D FOCUS goes one step further with an innovative image sensor that picks up both space and time to capture moving subjects with new clarity, allowing you to take crisper photos than ever. Plain-old AF is a thing of the past. The future of photography is in motion.
• Reliable AF down to EV-3 brightness - Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3, for more reliable autofocus in dark scenes.
