SONY Alpha A1 II Mirrorless Camera (Body Only)

A Fusion of Newly Featured Technology delivering top-tier performance

The massive volume of data from the 50.1 megapixel full-frame Exmor RS™ image sensor is processed in real-time by Sony’s BIONZ XR™ image processing engine. An advanced AI processing unit applies high-level subject recognition to reliably recognize a wide range of subjects. These state-of-the-art technologies make it easy to capture even the most challenging subjects in extraordinary resolution, with blackout-free viewing and full AF/AE tracking at up to 30 fps.

Optical 5-axis image stabilization achieves 8.5- step performance at the center

A high-precision image stabilization unit, advanced gyro sensors, and leading-edge algorithms detect and correct camera shake, achieving a groundbreaking up to 8.5-step effect at the center and 7.0-step at the periphery, and transforming handheld shooting with precision down to the single-pixel level and the finest subject details. With compatible lenses that include built-in stabilization, improved body-lens synchronization provides effective blur control even at otherwise problematic telephoto focal lengths.

Human eye recognition improved by up to approximately 30%

Real-time Recognition AF has improved human eye recognition by approximately 30%, and its human pose estimation technology also delivers precise recognition of subjects facing away from the camera, wearing sunglasses, or with their faces obscured. Recognition of distant human subjects occupying only a small part of the frame has been notably improved, so approaching subjects are recognized and tracked sooner. Subjects can also be tracked better across occlusions among many people.

AF tracking response settable to match subject speed changes

Fast Hybrid AF combines phase detection and contrast detection for superb speed, precision and tracking performance. 759 phase-detection points cover 92% of the image sensor. The AF tracking response for stills can now be selected from [Stable], [Standard], and [Responsive] to suit the likely subject motion, useful for example in bird photography. High AF precision is achieved right down to light levels as low as EV-4.0 in AF-S mode, with improved contrast AF response.

High frame rate recording at up to 120p

4K can be recorded at up to 120p right in the camera. 4K footage can be played back in up to 5x slow motion. The Slow; Quick Motion (S&Q) mode makes it convenient to play recorded footage back at slow or high speed in the camera. Full HD footage recorded at 240 fps offers even greater range: up to 10x slow motion (24p) to create impressive sports movies, for example. The frame rate setup menu allows intuitive selection of frame rates.

Consistently accurate exposure and color

Exposure and color reproduction are notably improved compared to the α1. The AE algorithm detects faces and optimizes exposure for stills and movies. Exposure stability has been improved by approximately 20%, even when the face is backlit and dark, or over-illuminated in direct sunlight, or not facing the camera. Working with a “Visible Light and IR Sensor” on the front of the body, the advanced AI processing unit helps to achieve accurate white balance even where the subject is in shade.

Framing Stabilizer automatically maintains subject position

Framing Stabilizer automatically maintains subject location within the frame when the camera operator is moving alongside the subject or in other situations where maintaining consistent framing can be difficult. AI-based subject recognition and Dynamic active Mode image stabilization maintain the composition and achieve stable imagery even when shooting handheld. [Center] mode automatically keeps the subject in the center of the frame, while [Manual] mode lets subject position be freely specified.

Dynamic active Mode stabilization 

In addition to standard mode, Active Mode combines a precision image stabilization unit and gyro sensor, while Dynamic active Mode adds electronic stabilization for an additional approximately 30%, enabling stable recording even when the user is jogging.

Flexible focus area settings

XL and XS focus area spot sizes are now available in addition to the existing L, M, and S. XS can be useful to avoid focusing on foreground objects such as branches. It is also possible to create a custom focus area of a specified size and aspect ratio, useful in situations like a track event where athletes are lined up side-by-side, and you want to focus on the leading runner.

Image playback functions that support immediate-delivery workflows

Multiple media playback lets you seamlessly display all images on two memory cards by selecting all slots as the display target during playback. Group display of images such as those shot continuously or with interval shooting is also supported. And if set in advance, a rating can automatically be applied to the first image in continuous burst or Pre-Capture groups, or a divider image inserted before the first image in groups, enabling quick scrolling through and location of groups using the custom dial during playback.

High-resolution 8K/4K recording for impressive realism

4K (3840 x 2160) movies can be cropped and edited from 8K source footage with overwhelming resolution from 8.6K oversampling. 8K 4:2:2 10-bit XAVC HS recording with optional Full HD proxy is available, as are 4K recording in XAVC HS, S, or S-I formats in full-frame, or Super 35mm size oversampled from 5.8K with full pixel readout and no pixel binning. XAVC S-I allows recording at up to 600 Mbps for outstanding image quality.
