Sony Alpha 7R IV sports a powerful 61.0 MP sensor

Sony has just announced the Alpha 7R IV. According to Sony, the new camera sports the world’s first 61.0 MP back-illuminated full-frame image sensor.

61.0 MP is a lot of pixels. In fact, it’s Sony’s highest-resolution sensor in a full-frame interchangeable lens camera. That’s a huge leap for Sony. The a7R IV’s predecessor, the a7R III, has a 42.4-megapixel sensor. So, it’s clear Sony is really honing in on its camera’s sensor sizes, pushing what is possible for a camera’s resolution.

With that megapixel count, the a7R IV should be able to shoot images that retain good quality, even when zooming in. But that’s not even the full story for the image quality. Sony says the camera also supports 15 stops of dynamic range at low sensitivities. That should result in smoother gradation from deep shadows to highlights.

Video and photo shooting

Now, let’s talk about video and photo shooting on the Alpha 7R IV. As said above, the camera has 15 stops of dynamic range with 61 megapixels of image data. It also features five-axis image stabilization and burst shooting at 10 fps (with continuous AF / AE for every shot), according to Sony.

The a7R IV can shoot 4K video with S-Log 2/3 for those who gravitate to the more professional side of editing. Also, HDR is supported as well, and the ISO range runs from 100 to 32000 (50-102400 expandable). The battery life of the camera allows for about 539 shots with its EVF, or 670 shots without.


The a7R IV has 10fps rapid shooting with continuous autofocus and autoexposure tracking capabilities. Furthermore, the camera has 567 phase-detect autofocus points that cover 74 percent of the frame and real-time eye autofocus tracking for stills and video.


There have been a number of improvements to the camera’s overall design. The viewfinders now is a 5.76-million-dot electronic viewfinder. Also, the camera’s grip has been redesigned with improved dust and moisture resistance. Additionally, the camera has dual UHS-II SD card slots and wireless tethering.
