Canon Eos R3 Features:

First, let’s check the key features of Canon EOS R3.

Image Sensor: 

Canon R3’s advanced 24 MP stacked image sensor is capable of speedy autofocus for wildlife & sports photography. As this stacked sensor matches up with Canon’s dual-pixel autofocus, R3 is more advanced than Sony’s masked pixel. The brand has also included the mechanical focal shutter for utmost convenience.


The magnesium alloy body of Canon R3 resembles the Canon 1D SLR. You can easily differentiate it from the Sony A1 & A9 series by its curved lines. It is relatively smaller and lightweight than Canon’s most recent flagship SLRs and 1D X Mark III.


You will definitely love this piece for its durable and weather-resistant handles. Its 3.2 inches display comprises 4.15 million dots. In comparison with the Sony A1, the R3 is more responsive.

Image Quality: 

In terms of dynamic range, Canon R3 offers far better performance than R5 or other mirrorless competitors. So, you can produce raw images with proper sharpness and reduced noise. You will definitely love its color accuracy and natural skin tone. However, in terms of resolution, the 45 MP R5 and Sony A1 can beat the 24 MP R3 sensor. 


Canon EOS R3 is a speedy camera with a shutter speed of up to 1/64,000th second on electric mode. You can capture fleeting moments at a burst rate of 30 fps with a silent electronic shutter. It allows you to take a minimum of 150 shots. With the 12 fps burst Rate of the mechanical shutter, you can capture 1000 raw images.

Eye Control Autofocus: 

Its eye control autofocus functions well to capture fleeting moments as well. We won’t say it’s the best, but it’s the first R-series mirrorless camera with such a feature.

Video Quality: 

Canon R3 is definitely the best mirrorless camera for sports videography. You can capture 6k raw videos at a speed of 60 fps. Use All-I capture to shoot 4k videos at the frame rate of 120 per second. We would recommend using the CFexpress card instead of SD-UHS II as it is quite slow. 

All the videos captured at 60p or 30p 4k mode are pretty sharp and detailed. Moreover, Canon R3 won’t overheat during oversampling 4k videography. You can also capture 4k 60p and 6k raw videos without any temperature warning for at least 1 hour. 4k 120 fps videography has a time limit of 12 minutes. We believe it won’t affect your regular videography.

Is Canon EOS R3 Worth It? 

Canon R3 is a flagship-level camera with a 24 MP CMOS sensor exceptionally suitable for photojournalism. Its litany settings and autofocus let you capture the highest quality videos as well. 

It is the first camera of the R-series with a stacked sensor, backside illumination & eye control AF. If you have the budget, it’s indeed the best option, especially for wildlife & sports photography.
