Sony today announced the latest addition to its acclaimed Alpha 7R series full-frame mirrorless camera line-up; the extremely versatile, powerful Alpha 7R IV (model ILCE-7RM4).

Sony's highest resolution full-frame camera ever, the new Alpha 7R IV delivers stunning image quality with high resolution and wide dynamic range while maintaining outstanding focusing performance, high-speed continuous shooting and much, much more.

We are continuing to drive innovation, break boundaries and redefine the expectations of digital camera performance, said Yann Salmon Legagneur, Director of Product Marketing, Digital Imaging, Sony Europe. The new Alpha 7R IV combines medium format level image quality with high-speed shooting, extremely fast focusing and a long list of upgrades to design, connectivity and usability. This will allow professional photographers, videographers and all other types of creators to capture content in ways that were simply not possible before.

A New Level of Image Quality

The new Alpha 7R IV features a newly developed 35mm full-frame back illuminated CMOS image sensor with a resolution of 61.0 MP,ii the world's firsti 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-stopiii 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.

This new full-frame model is equipped with an innovative 5-axis optical in-body image stabilisation system that has been fine-tuned to support its high-resolution shooting capacity, resulting in a shutter speed advantage of 5.5-steps.[x] Additionally, the shutter unit assembly has been carefully re-designed to reduce even the slightest movement that may cause blur.

The Alpha 7R IV also includes Sony's highest resolution viewfinder in any camera, a 5.76 million dot UXGA OLED Tru-finder EVF. About 1.6x the resolution of the EVF in the Alpha 7R III, this new viewfinder provides an extremely accurate, true-to-life depiction of the scene being framed. The display quality can be set to Standard' or High' mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.

Additionally, the new camera features an evolved Pixel Shift Multi Shooting[xi] mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in 1 or 0.5-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels worth of data then composited into a 240.8 million pixels (19008 x 12672 pixels) image using the Imaging Edge desktop application.[xii] Ideal for photographing architecture, art or any other still life photography subject, this enhanced mode produces photographs with a level of detail and colour accuracy that is simply stunning.

Shooting and Focusing Speed

The innovative new Alpha 7R IV full-frame mirrorless camera can shoot full resolution images at up to 10 fpsiv with continuous, accurate AF/AE tracking for up to approximately 7 secondsv 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 IV 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.

The Alpha 7R IV also supports Real-time Eye AF, which employs artificial intelligence to detect and process eye location data in real-time, stay locked onto the subject's eye with extreme precision. This is available for
