Burst Shooting and Buffer Capacity

The Canon R3 has an outstanding burst rate of 30 frames per second, which propels it to the front of the pack in this particular category.

Because of its enormous buffer, it is possible to film continuously for longer periods of time without experiencing any slowdowns. The Canon EOS R6 II, on the other hand, can shoot at a reasonable 20 frames per second despite having a lower buffer capacity.

Video Capabilities

If shooting video is a big part of your job, the Canon EOS R6 II might very well be the model that best suits your needs.

It permits recording at an 8K resolution, in contrast to the Canon R3, which concentrates on offering exceptional performance for still images but also has remarkable 4K video capabilities.

ISO Performance

The Canon EOS R6 II shines when it comes to ISO performance, providing exceptional low-light skills with a relatively low level of image noise.

The Canon R3 deserves praise for its remarkable performance in this respect as well, despite the fact that it falls short of its competitor in other respects.

Ergonomics and Build Quality

Ergonomics is extremely important for photographers since they frequently hold their cameras for extended periods of time.

The Canon R3 has a magnesium-alloy body that is both weather-sealed and rugged; this contributes to the camera’s superb durability and comfortable grip. Even though it is well-built, the Canon EOS R6 II is not as tough as its predecessor, the R3.

Viewfinder and LCD Display

The Canon R3 is equipped with an outstanding OLED electronic viewfinder that features 5.76 million dots, resulting in a shooting experience that is extraordinarily detailed and immersive.

Even though it has a decent viewfinder, the Canon EOS R6 II is not up to level with its competition.

Connectivity Options

Wi-Fi, Bluetooth, and USB-C are just some of the connectivity choices that are available with any of these cameras.

On the other hand, the Canon R3 comes with a brand-new wired LAN connection, which is perfect for businesses that demand extremely quick data transfer.

Battery Life

The Canon EOS R6 II features a battery life that is respectable and is able to go through a whole day’s worth of photography.

Although it is not as powerful in this area, the power offered by the Canon R3 is suitable for the majority of shooting conditions.

Price Considerations

As was to be expected, the cutting-edge capabilities that come standard on the Canon R3 come with a hefty price tag.

On the other hand, the Canon EOS R6 II is an alternative that comes at a lower cost while still giving performance that is truly outstanding.
