Both 24 megapixel full-frame mirrorless cameras, the Canon EOS R1 and R3 have a strong focus on giving as much speed as feasible for sports and wildlife photography.
Regarding their basic characteristics and qualities, they are somewhat comparable; hence, which one should you choose?
To assist you in selecting between these two full-frame cameras, we are presenting a head-to---head comparison of Canon EOS R1 and Canon EOS R3.
To find out exactly what we believe of each one in far more depth, you can also read our comprehensive Canon EOS R1 and Canon EOS R3 reviews.
Sensor
These cameras have quite comparable megapixel counts and apply quite distinct sensor technology.
Comprising a brand-new 24.2 megapixel full-frame back-illuminated stacked CMOS sensor with a 16 point low-pass filter, the Canon EOS R1 is
With comparable 24 megapixel resolution, the EOS R3 also has a stacked back-illuminated sensor, same as the R1.
Thus, both models use a stacked CMOS sensor with inbuilt memory, which offers considerably quicker burst speeds than cameras without and better performance overall.
Faster all-round performance and improved low-light image quality at like-for--like ISO speeds might come from Back-Side Illuminated (BSI) sensors.
CPU
While the R1 features the DIGIC X processing coupled with a brand-new DIGIC Accelerator processor, the EOS R3 runs the newest DIGIC X processor.
Together with Deep Learning technology, the new "Accelerated Capture" dual processor imaging architecture on the EOS R1 facilitates the processing of vast amounts of data. Higher performance, better auto focusing, continuous shooting and image quality follow from this.
ISO Pace
The Canon R3's native ISO range is 100–51200, which one may extend down to ISO 50 and then up to ISO 102400.
Running from 100-102400, the Canon R1's native ISO range is somewhat broader; one may extend it down to ISO 50 and up to 204800.
While deep learning noise reduction may cut noise by two stops, in-camera upscaling on the R1 only can increase up to four times the original resolution without degrading clarity.
Visual
The Canon R1's major video specifications include 2K or Full HD at 240p in XF-HEVC S / XF-AVC S formats; 6K 60p RAW in-camera, 4K 120p, 4K 60p oversampled from 6K.
It provides minimum rolling shutter, Canon Log-2 / Log-3 / HLG profiles, bespoke images, proxy video compatibility and 4-channel 24-bit audio among 16+ stops of dynamic range.
Apart from oversampled 4K video at up to 120p, the EOS R3 also enables 6K/60p internal recording. It supports 10-bit 4:2:2 DCI 4K video running up to 60fps.
With its mic and headphone connections and micro-HDMI Type-D port for output to an external recorder, the R3 offers infinite recording durations with no overheating and lets up to six hours of regular video or 90 minutes of full HD high frame-rate film to be shot.
AUTofocus
Along with a vehicle tracking mode, which lets you deftly track motorbikes, open cockpit Formula cars as well as GT and rally cars, and even allows you to prioritise the vehicle or the driver's helmet, the Canon R3 boasts the most advanced version of Dual Pixel CMOS AF that the company has ever produced with 4779 AF points.
Using the electronic viewfinder, the Canon R3 also lets you choose and relocate the AF point merely with the glance of your eye. Without even touching the camera settings, this provides the R3 a considerable benefit in terms of rapidly being able to focus.
By measuring the head area, the new Dual Pixel Intelligent AF technology shown on the R1 provides a superior tracking algorithm capable of detecting subject crossing/upper half of body and avoiding obstructions.
Deep learning tech is used in the new Action Priority subject tracking mode for football, basketball and volleyball to identify where the action is and relocate the AF point to that subject at up to 60fps. Depending on the sport, it can rapidly detect and identify several persons, condition of joints and ball placements, and automatically ascertain the main topic and action stance.
When capturing both images and videos, subject tracking can now identify horses, aeroplanes, trains in addition to humans, animals and motorsport cars.
With the capacity to record 10 files on a memory card each with 10 registered faces, the Registered People Priority mode can recognize and prioritize up to 10 faces even in side profile, perfect for sports, news and weddings.
By just staring at them in the electronic viewfinder, the R1's eye control AF function allows you choose focus points or subjects to monitor.
Thanks to a higher pixel count sensor, better LEDs, bigger eye detection area, updated detection algorithm, and two times quicker eye movement detection speed, eye control AF on the R1 delivers increased performance when compared to the R3 model on which this feature initially made its debut.
Burst Accuracy
For 540 JPEG or 150 RAW shots, the Canon R3 offers 30fps shooting with the electronic shutter combined with complete AF/AE tracking and low image distortion.
On the EOS R1, burst shooting rates are specified as either 12fps with the mechanical shutter or 40fps continuous shooting with the electronic shutter.
Before completely hitting the shutter button, pre-continuous shooting up to 20 shots ( Raw or JPEG/HEIF) is also newly accessible.
Shutter
Thanks to their electronic shutters, both cameras have a rather quick maximum shutter speed of 1/64,000th second.
Anatomy
With replicated vertical controls that EOS-1D series DSLRs have traditionally provided, both cameras have a same integrated vertical grip design.
As would be expected from such professional quality devices, both are also totally weather-sealed.
The R3 is somewhat smaller and lighter than the R1.
Measure 150 x 142.6 x 87.2mm and the EOS R3 weights in at 822g body-only or 1015g with a battery and memory card inserted.
Measures 157.6 x 149.5 x 87.3 mm and weights in at 920g body-only or 1115g with both a battery and memory card inserted.
Battery Run-through
The LP-E19 series battery powers both cameras; it gives up to 620 shots when using the viewfinder and 860 shots when using the LCD monitor on the R3 and up to 700 shots when using the viewfinder and 1330 shots when using the LCD monitor on the R1.

Both cameras use the newer USB-C type and can also be powered and charged via a USB connection, which is handy if you're out and about and have a suitable powerbank to put the camera into.
Fee
The Canon EOS R1 is €7999 in Europe and £6999 body only in the UK.
End
Whether or whether you will gain from the two processing technology of the new Canon EOS R1 and the consequent enhancements to auto focusing, continuous shooting, and picture quality, truly boils down depending on this. Otherwise they are rather equally matched.
Hence, what do you believe? Which EOS R3—the somewhat older and less expensive one or the newer, more costly one—would you prefer? Leave a remark down below!
