Just two years after the launch of the original EOS R6, Canon has unveiled its successor, the $2,500 EOS R6 Mark II. It brings a number of key improvements, like a higher-resolution 24.2-megapixel sensor and faster shooting speeds. Most importantly, Canon has significantly reduced the previous model’s issues with overheating.

The EOS R6 was the best camera in this important price range when it launched, thanks to the speed, powerful video features and excellent Dual Pixel hybrid autofocus. However, once Sony’s $2,500 A7 IV came along with comparable abilities, more resolution and no overheating problems, the R6 lost that particular crown.

At a preview event in San Diego, Canon let me shoot with R6 Mark II prototypes for a couple of days in a variety of sports situations. As it’s not a production model and still had a few bugs, this isn’t a final review – but it gave us a chance to share some early impressions.

Body and handling

The EOS R6 II isn’t just a slightly updated ‘A’ version of the original. It has significant physical and performance changes, starting with the new 24.2-megapixel sensor. It’s not, as rumors suggested, the stacked backside-illuminated (BSI) sensor from the EOS R3; there’s a reason that model costs so much. But it does offer some benefits over the 20-megapixel chip on the R6.

Canon promises improved image quality beyond just the extra megapixels, thanks to the updated image processing. It also offers improved low-light sensitivity despite the slightly smaller pixels. And Canon says that rolling shutter is reduced over the R6.

The R6 features some changes on the outside as well. The power/lock/off switch is now positioned at the right where it’s easier to access yet harder to hit by accident. It also has a new video/photo mode switch that keeps those functions, and all their settings, separate. Flipping it also changes the menus, and Canon has introduced a convenient video-specific Q menu.

Otherwise, it's roughly the same weight and size as the R6, and has an identical grip, menus, control layout and handling. It also uses its predecessor's, nice flip-out display for vlogging or selfies, dual UHS II card slots and 3.67-million-dot electronic viewfinder. And, of course, it comes with microphone and headphone ports, along with a USB-C socket and (unfortunately) a microHDMI jack. It has a new in-body stabilization (IBS) system, but it offers the same 8 stops of shake reduction as the EOS R6.
