Sony’s latest full-frame mirrorless camera, the Alpha a7 IV, seeks to redefine what it means to be an all-around full-frame mirrorless camera. Inheriting a BIONZ XR image processor and AI-based AF from Sony’s Alpha 1 flagship camera while unveiling an all-new 33MP Exmor R image sensor, the a7 IV promises to be an attractive mid-tier entry into Sony’s full-frame mirrorless system. With special attention paid to advancing photo and video functionality, the a7 should appeal to hybrid creators looking for a camera capable of bridging the still-video divide with ease. Alongside the new camera, Sony has announced two new flashes: the HVL-F46RM and HVL-F60RM II wireless radio flashes.
The a7 IV is built around a 33MP Exmor R back-illuminated CMOS sensor, which provides an instant boost in resolution over Sony’s existing entry-level full-frame cameras. Pushing the a7 IV further into new territory for what Sony describes as a “basic” camera is the inclusion of a BIONZ XR image processing engine, Sony’s most advanced to date and the same used by the Alpha 1 and a7S III cameras. Together, they provide 15 stops of dynamic range for accurate color rendering for still and video capture. Ready for nearly any lighting environment, the a7 IV has a native ISO range of 100-51200 which can be expanded to 50-204800 when shooting stills or 100-102400 when shooting video.
