The Sony A7R IV is the current pound for pound resolution king when it comes to Full Frame Mirrorless cameras.
Earlier this summer, Sony announced its latest high-resolution flagship Full Frame Mirrorless camera, the Sony A7R IV, which was met with an overwhelmingly positive reception. At the heart of the Sony A7R IV is its brand new, 61MP, backside-illuminated sensor. As of press time, this sensor is the highest resolution sensor available in a Full Frame camera. This takes the A7 series into medium format resolving territory. The Sony A7R IV also packs the company’s latest generation AF technologies under its hood, including Face and Eye AF for Humans and Animals, in addition to Real-time Tracking. The exterior of the A7R IV went under the knife as well, resulting in a slightly larger body that includes a deeper handgrip, better joystick, improved rear dial, a lockable Exposure Compensation dial, and upgraded buttons all around. The excellent Electronic View Finder from the A7R III was also replaced with a higher resolution EVF now capable of refreshing at up to 120 fps. Weather-sealing has been one of Sony’s pain points, but this also saw a major overhaul in the A7R IV. All of these improvements culminate in a camera designed clearly with the professional in mind.
