The A7R IV may have been pulled out of first place by the Fujifilm X-T4, but it still deserves a place on this list. Simply put, even if it may be overkill for many photographers and situations, a full-frame sensor will easily outperform smaller APS-C sensors, like the one on the X-T4, when it comes to low-light performance and depth of field . control. As the first company to produce a full-frame mirrorless camera, Sony remains the leader in this race, even as Canon, Nikon, and Panasonic have begun to race to achieve it. But the surprising thing is how much Sony managed to fit a camera with such a compact body.
The A7R IV’s sensor now boasts 61 megapixels, the highest resolution you’ll find compared to larger, medium-format cameras. The sensor also offers excellent dynamic range, great color, and low noise performance at high ISOs.
But megapixels aren’t everything, and Sony hasn’t forgotten. The A7R IV has the performance to match, producing full resolution bursts at 10 frames per second with autofocus. Sure, the X-T4 is faster, but considering the massive bandwidth requirements of Sony’s 61-megapixel sensor, that’s pretty impressive.
The A7R IV also uses Sony’s latest real-time autofocus, one of the best autofocus systems we’ve tested, hands down the best in mirrorless. It offers decent low-light sensitivity, good speed, and the best facial and eye tracking you can get.
The electronic viewfinder, the same 5.7 million-dot OLED panel first introduced on the Panasonic Lumix S1, is the best in the business. It is enough to influence any photographer who is still hanging on the optical viewfinder of a DSLR.
Despite all the internal technology, the camera body weighs just 23 ounces. Body is sealed from the weather, with a control scheme that feels balanced and easy to use (though Sony’s menu system is still a pain point), and the new battery is good for 670 exposures, which is excellent. for without mirror.
