The sensor in the Canon EOS R3 is key to the image quality the camera is capable of, and it’s Canon’s first ‘stacked’ CMOS sensor to date. Let’s take a quick look at how it compares to other cameras of similar pixel counts.

Our test scene is designed to simulate a variety of textures, colors and detail types you’ll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.

We’ll be going into a full analysis in our full review, but we can see off the bat that the R3 turns in competitive detail in its class. Differences between it and other cameras with similar resolution will predominantly come down to their anti-aliasing filters (or in more consumer-oriented models, the lack thereof).

Let’s take a brief look at dynamic range as well.

We were curious as to what extent – if any – the EOS R3’s super-fast electronic shutter might be adding noise, and the answer appears to be ‘not much’. You have to get into the super-deep shadows, pushing between 5 and 6 stops, to really see a difference. That’s a promising result and indicates that you can use the e-shutter in most any situation without having to worry about a substantial impact on image quality.
