A New Level of Image Quality

The new Alpha 7R IVa features a newly developed 35mm full-frame back illuminated CMOS image sensor with a resolution of 61.0 MP, the world’s first of its kind. The new sensor’s back-illuminated structure and effective noise reduction techniques combine to deliver extremely low-noise, high sensitivity performance ensuring the absolute maximum image quality. The camera also boasts an impressive 15-stops if dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilises algorithms from many of the latest Alpha™ cameras to maintain outstanding colour reproduction.

Shooting and Focusing Speed

The innovative new Alpha 7R IVa full-frame mirrorless camera can shoot full resolution images at up to 10 fps with continuous, accurate AF/AE tracking for up to approximately 7 seconds in full-frame, full-resolution mode (JPEG / RAW), and approx. 3x seconds in APS-C crop mode delivering 26.2MPii images. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.

The upgraded focusing system of the Alpha 7R IVa is comprised of 567 focal-plane phase-detection AF points that cover approximately 74% of the image area. There are also 425 contrast AF points that add extra precision and reliability for low light and other situations that are best served by contrast AF. The higher AF sensor density and refined tracking algorithms of the new camera produce a notable improvement in tracking performance, allowing complex subject motion and sudden subject movements to be reliably tracked with greater precision than ever.

High-resolution 4K and Professional Filmmaking Features

In addition to its impressive still image capabilities, the new Alpha 7R IVa performs exceptionally well as a serious filmmaking tool, offering 4K (3840x2160 pixels) video recording and full pixel readout without pixel binning in Super 35mm mode. This ensures high-quality 4K footage with exceptional detail and depth. S-Log 2 and S-Log 3 are also available to maximize colour grading flexibility, with S-Log 3 offering a total of 14-stops of dynamic range. HLG (Hybrid Log-Gamma) is also available on the Alpha 7R IVa to support an Instant HDR workflow.

Enhanced Build, Design and Customisability

To maximise durability, the new Alpha 7R IVa features upgraded dust and moisture resistance, with additional sealing provided at all body seams, the battery compartment cover and media slots. The camera is built with an extremely lightweight and durable magnesium alloy, and has an upgraded six screw, extra-firm mount.
