The Sony A7R Mark IV’s 61-million-pixel 35mm sensor is a world first, which the company says delivers ‘medium format quality’ in its announcement livestream.
The sensor is a new generation and back-side illuminated, and it provides 15 stops of dynamic range. As well as 61-megapixel images, the Sony A7R Mark IV can also produce images with 26 million pixels in APS-C crop mode.
What’s more, its revampled Pixel Shift Multi-Shooting mode can produce images at 240-megapixel resolution. It does this by capturing 960 megapixels worth of data from 16 images, which it then composites together using Sony’s Imaging Edge software.
The A7R Mark IV boasts 567 phase detection AF points in full-frame mode, which cover 74% of the frame. In the camera’s APS-C mode it has 325 AF points which then cover nearly the entire frame.
Sony says the A7 IV is also built for speed. It can capture full-resolution 61-megapixel images in continuous shooting mode, and up to 68 images per continuous burst.
Sony says the A7R Mark IV also includes its AI-driven Real-time Eye AF and Real-time Tracking modes.
Also among its key features is 5.5-stop, 5-axis in-body image stabilisation, wireless tethering capability, faster USB connection, 802.11ac Wi-Fi plus Bluetooth and studio lighting support.
Sony A7R Mark IV Video Specs
The Sony A7R Mark IV can record 4K video using the full width of the sensor for capture. Also, for the first time, Sony has included real-time Eye AF for movies – the first time for video capture.
Other Sony A7R IV video specs include S-Log3 mode for capturing wide 14-stop dynamic range and Hybrid Log-Gamma mode.
As for audio, Sony has included a new digital audio interface between the microphone and camera. A conventional microphone sends an analogue signal that the camera converts to a digital format. But Sony’s new digital microphone, the ECM-B1M, transfers the audio signal from the microphone through the A7 Mark IV’s Multi-Interface Shoe to record digitally directly to the codec.
Sony A7R Mark IV body design

Sony says it has improved the A7 Mark IV’s grip and also provided enhanced dust and moisture resistance, as well as a sealed chassis.
