Sony A7R IV hands-on review: 61 glorious megapixels

That statement is pretty incredible when you recall people jumped up-and-down over the 42MP A7R II just a few years ago. Yet here we are in 2019 and the numbers keep soaring into the stratosphere. Not that we're complaining, mind you — especially since...

61MP full-frame sensor 240MP pixel-shift mode 10 fps continuous shooting 4K video in full-width and crop modes Real-Time autofocus

Benefits of 61MP may be limited Sony menus remain problematic

Sony a7R IV Review

The Sony a7R IV ($3,499.99, body only) is the follow-up to the popular a7R III. It takes the same concept—a full-frame mirrorless camera built for high-resolution capture—to the next level. Where the previous two entries in the series shared the same...

60.2MP full-frame imaging. 10fps Raw capture. Real-Time Tracking autofocus. 5-axis image stabilization. Big, crisp EVF. Tilting touch LCD. Dual UHS-II slots.

Lower-pixel cameras are better for video. Phase detection doesn't extend to edge of frame. Big file sizes.

The full-frame mirrorless Sony a7R IV outshines its high-resolution competition with an outstanding autofocus system and a superlative image sensor, delivering class-leading performance.

Sony A7R IV review: Here's to new resolutions

Sony's ultra-high-res full-frame mirrorless camera sports 61-megapixels. But what's its overall feature set like and does it trump the MkIII model?

Huge resolution ; Extensive and capable AF system ; High resolution viewfinder ; Great battery life

Limited touchscreen ability ; Restricted screen angle adjustment ; No 60p option in 4K or 10bit capture ; Body not a slim as it once was

The Sony A7R Mark IV delivers medium-format-level detail without sacrificing on performance. And while you do pay a significant premium for the privilege, high-resolution mirrorless cameras don't get any better than this.

Sony Alpha A7R IV review

Sony has spent much of the past year proving just how seriously it’s taking the needs and demands of enthusiast and pro photographers. It updated its flagship compact proposition with the RX100 VII, while the Alpha A6400 , Alpha A6100, and Alpha...

Great handling with improved ergonomics Very fast and intelligent AF system Bright, sharp and high-contrast viewfinder Excellent 4K video quality Pixel Shift Multi Shot capable of superb detail Well-behaved metering system

Some AWB and focus issues Rolling shutter noticeable in videos Mode dial more awkward to access than before Touchscreen could be better No in-camera raw processing No motion correction in Pixel Shift mode

The A7R IV proves that Sony is still very much on a roll with its Alpha line. While a handful of niggles from previous models remain, the class-leading pixel count, revamped Pixel Shift Multi Shooting mode and autofocusing improvements in particular...

Sony A7R Mark IV review

The Sony A7R Mark IV should not be thought of solely in terms of resolution, but that 61MP sensor is bound to be what grabs all the headlines. It beats its full frame rivals by some margin and re-establishes Sony as a front-runner in a full-frame...

World record resolution! Better handling than the Mark III Eye-tracking AF 10fps shooting

No 60/50p video Small body/big lens imbalance Ageing design and handling

The A7R IV’s design tweaks make it handle better than the A7R III before it (though it can still be tiresome), and the resolution puts it well ahead of all its full frame mirrorless rivals for megapixels. And yet… while Sony’s hybrid AF system just...
