Canon EOS R5 vs Sony A7R IV

It's no secret that Sony has dominated the full frame mirrorless game these past couple of years with its unmatched autofocusing and dynamic range. Unfortunately, Canon and Nikon were late to the game coming out with their first mirrorless cameras back in 2018. Now, two years later, Canon has made huge strides forward with the release of the EOS R5 and R6 cameras, closing the gap on Sony. 

When the EOS R came out, many Canon DSLR shooters were still wary of switching over to the mirrorless ecosystem. But it's a whole new ball game with the launch of the EOS R5 which has loyal Canon users jumping at the latest mirrorless system. 

Let's take a look at the two high megapixel mirrorless powerhouses of 2020—the Canon EOS R5 vs. the Sony A7R IV. It's almost impossible to find a camera that meets the needs of every photographer, but for high resolution full frame still cameras, these two come pretty close.

Both cameras are fairly new with Sony's release date back in July 2019 and Canon's in July 2020. With a year apart, there are a few advantages the Canon has over the Sony but with everything considered, there are pros and cons to both cameras. 

Resolution & Processing Power

To start, the obvious difference is the megapixel count. The Canon having 45MP while the Sony has 61MP. Considering both exceed the average amount of resolution in a full-frame camera, the Sony A7R IV still has a leg up on the Canon R5 in terms of flat out resolution detail to work with for stills. Sony takes it even further with its pixel shift capability to create up to 241MP images available for still life photographs. 

However Canon's newer processor is able to utilize their 45MP sensor to capture impressive 8K RAW video footage, an industry first for a camera at this price range, albeit with heat restricted record limits. Regardless, photographers should take into account the amount of storage needed for such large files.

Camera Design and Construction

In terms of the actually physical characteristics of each camera, the size of the EOS R5 is going to be just a bit bigger than that of the Sony A7R IV but not by much. One major difference in the ergonomics is that the R5 has two LCD screens, one the back of the camera as well as a top display for camera settings, battery life metrics and more. On the same note, the Canon features a fully articulating LCD touch screen while the Sony comes with a tilting touch screen. Both are made with magnesium alloy bodies and are weather sealed. 

One major feature that Canon users rejoiced about in the EOS R5 was the addition of a second card slot. Both the Sony A7R IV and Canon EOS R5 come equipped with two slots but now the R5 has one slot compatible with the newer and faster CFexpress memory card as well as a UHS-II slot. The Sony on the other hand provides two UHS-II card slots. 

Battery Life 

When comparing battery life, the Sony is considerably better with its FZ-100 battery. It has estimated 670 shots per full charge compared to 320 in the Canon. In addition, both cameras have the ability to be charged via USB, but the Sony has the option to charge while in use. For more peace of mind for either camera, it's smart to have extra batteries on hand or a battery grip.

Lens Selection

Although, not everything is weighed by the features of the body alone, users also should consider the selection of mirrorless lenses available. Since Sony mirrorless has been around for much longer, they have a larger range of native brand lenses available with 44 options compared to Canon's 15. Sony also boasts dozens more high-quality and affordable 3rd party lens options from manufacturer's like Tamron and Sigma. 

We took matters into our own hands and tested both cameras with the same settings. The images above were taken handheld at 1/125th of a second, 70mm, F2.8 at ISO 800. The Canon image is definitely warmer straight out of camera and is apparent on the model's face and the walls, while the Sony renders a cooler image and highlights more green tones in the computer screen. Both cameras are capable of producing amazing images and with RAW recording can be shifted in anyway the photographer prefers. So which direction are you leaning?

If you’re talking about adapters, then the Sony can also use most of the Canon lenses without issues with an EF to E adapter. Also isn’t that canon RF lens a 28-70 f2 not 24-70? 4mm might not be a deal breaker but it also could ::shrug::


If we talk about lenses it’s worth to mention that you can use all your EF Canon lenses with adapter without losing quality – adapter is without any lens.

Also – with Canon made 24-70 f2 lens for new RF mount, that’s outstanding, so far Sony has only 2.8 for the same range.
