The Canon EOS R3 is one of the most technologically advanced cameras that Canon has produced. Improvements to the autofocus alone put the Canon EOS R3 ahead of almost every camera that Canon has ever produced. Despite this, Canon maintains that the EOS R3 is not a 1 series flagship camera.
The Canon EOS R3 is the priciest RF mount camera to date. With a price point of almost $6,000, it sits uncomfortably close to the Canon 1D X Mark III, the current Canon flagship camera. The Canon EOS R3 includes a number of improved features, such as video quality, autofocus, and a significant jump in the number of frames it can capture per second, albeit with the electronic shutter. However, the Canon EOS R3 is still not considered a flagship camera by Canon.
In a recent discussion with Canon, it was confirmed that the EOS R3 camera does not replace the Canon 1D X Mark III to become the new flagship. The key reason it's not considered a flagship camera is that the 1D series cameras are designed to operate in far more challenging conditions. Although the EOS R3 does have similar weather-sealing when the hot shoe cap is attached, it may not be as capable in tougher environments.
Interestingly, this could end up being a challenge for Canon. If a $6,000 camera is not a flagship camera for Canon, what will an actual 1 series RF mount camera cost? Also, what kind of features could we see in a potential 1 series RF mount camera?
It is, however, important to mention that there are a few features the 1D X Mark III holds over the EOS R3. These include a larger buffer and the ability to shoot much faster using the mechanical shutter. The 1D X Mark III can manage 20 frames per second for up to 1,000 images, whereas the EOS R3 can only manage 12 frames per second with the mechanical shutter. It's also limited to a maximum of 150 images when shooting at 30 frames per second with the electronic shutter.
In general, photographers that shoot with 1 series cameras expect zero compromises. And based on what the EOS R3 can do, Canon may have something remarkable planned for its first-ever RF mount flagship camera.
