Five months on from its first announcement, the Canon EOS R3 has finally been given a full official launch – and we now know the missing pieces in the pro camera's spec sheet. (Looking to read our first impressions? Head to our hands-on >Canon EOS R3 review).
The EOS R3 is the most powerful mirrorless camera Canon has made so far, and sits in between the smaller Canon EOS R5 and Canon EOS 1D X Mark III DSLR – although in reality it's the mirrorless successor to the latter.>
So what new things have we learned? We already knew that the EOS R3 was going to have a new stacked CMOS sensor and be able to machine gun raw photos at 30fps with full AF/AE tracking.
Canon had also previously revealed in a June 'development announcement' that the EOS R3 would have new vehicle-tracking autofocus, an articulating touchscreen, eight stops of in-body image stabilization (IBIS) and the ability to shoot oversampled 4K video.
But this full announcement gives us some key details, including its sensor's 24.1MP resolution, that help us weigh up exactly how advanced this action-focused camera is – and how Canon's mirrorless tech is stacking up next to its Sony rivals.
1. It has a 24.1MP stacked sensor
As we suspected after some internet sleuths grabbed the EXIF data from some EOS R3 photos at the Olympics, Canon's new mirrorless camera has a stacked sensor with a 24.1MP resolution.
That resolution might sound a little miserly compared to the 50MP Sony A1, but the EOS R3 is primarily a sports and wildlife camera – and it's higher-res than the 20.1MP Canon EOS 1D X Mark III, which pro snappers have happily relied on for the last eighteen months.
