The Sony Alpha a7R IVA continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance, and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP Exmor R BSI CMOS sensor and enhanced BIONZ X image processor, which affords impressive imaging results with marked smoothness, a 15-stop dynamic range, and, of course, speed. Up to 10 fps shooting is possible along with the ability to record UHD 4K30 video, both with support for Real-time Eye AF and Tracking AF technologies. Despite being such a high-resolution sensor, it is also distinguished by its flexible native sensitivity range from ISO 100-32000 for working in a variety of lighting conditions. 

In terms of usability, the OLED electronic viewfinder has been boosted to an impressive 5.76m-dot resolution for clear viewing and the 3.0" rear tilting touchscreen LCD has a high 2.36m-dot resolution for crisp playback, live view shooting, and menu navigation. Complementing the camera body is a trio of accessories to increase battery life and enhance audio recording capabilities when shooting video. the full-frame 61MP Exmor R CMOS sensor works with the BIONZ X image processor to offer impressively high-resolution stills and video while minimizing noise, improving speed, and achieving a wide 15-stop dynamic range. This sensor structure works with a gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail.

The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture this impressive 15-stop dynamic range with smooth tonal rendering. This focusing system also achieves especially quick speed and reliable tracking, as well as enhanced low-light focusing response down to -3 EV. Additionally, Eye AF can be used to base focus on recognized human subjects' eyes for portraits and is available in both AF-S and AF-C modes, for both stills and video. Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details. 

An updated UXGA OLED Tru-Finder EVF is featured and has a 5.76m-dot resolution for bright, clear viewing in rich detail, and a dedicated High-quality setting enables a 120 fps refresh rate for especially smooth playback of moving subjects. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding. Built-in Wi-Fi enables the a7R IVA to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. Support for both 2.4 and 5.0 GHz bands also enables wireless tethered shooting support. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake. All shooting styles will get usage out of the roll compensation.

All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization. Full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire sensor width. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling.  
4K video recording also avails the ability to produce 8MP stills during playback by taking a frame grab from a movie and storing it as a separate file.
