Backscatter Publishes Review of the Sony a7R Mark IV
By Ian Bongso-Seldrup, February 28, 2020 @ 08:00 AM (EST)

When Sony released the fourth iteration of its highly regarded a7R series, it was also a reminder to everyone that the Japanese giant is the planet’s sensor king: The a7R Mark IV packs a 61-megapixel BSI-CMOS sensor, leaving its 42MP predecessor—and even the 47MP Panasonic S1R—in the dust. Add Sony’s class-leading subject tracking, DSLR-level autofocus system, and effective 5-axis image stabilization, and you’ve got a serious tool for shooting both stills and video.

That’s the theory anyway, so no wonder Backscatter hasn’t wasted any time getting the a7RIV in the water (this time, Little Cayman and Bali) to see how well the camera fares in practice. In the company’s latest review, CEO Jim Decker puts the full-frame mirrorless through its paces with subjects ranging from gobies and nudibranchs to turtles, rays and barrel sponges.

Jim concludes that the Mark IV “will produce big prints with tons of sharp detail like no other camera before it” and applauds the Real-time Tracking AF and 10fps continuous shooting speed (“crazy” when you consider the massive file sizes involved), while also lamenting the lack of 4K/60p video and underwhelming white balance abilities at depth. For Backscatter, though, the a7RIV still represents “the hands-down best stills image quality and biggest resolution” available.

Read the full review on Backscatter and enjoy Jim’s impressive test images and footage.
