Canon EOS R10 versus 90D


Canon launched its first APS-C format cameras in its mirrorless EOS R system in the form of the Canon EOS R7 and Canon EOS R10. While the R7 is intended to carry the torch of Canon’s speedy EOS 7D DSLRs, the R10 would be the next step up in its versatile double-digit DSLRs. So, in essence, the Canon EOS R10 is the natural successor to the last of them, the EOS 90D. In this guide, we’ll look at how the two APS-C sized cameras stack up in our Canon EOS R10 vs 90D comparison.


Canon EOS R10: 24.2 megapixel (22.3 x 14.9 mm) APS-C format CMOS
Canon EOS 90D: Format 32.5MP APS-C (22.3 x 14.8mm)

The Canon EOS 90D features a 32.5-megapixel APS-C format Dual Pixel CMOS sensor. This is the same sensor used in the EOS M6 Mark II and is very similar to the chip used in the new Canon EOS R7. The difference between the 90D and R7 sensors, according to Canon, is that the latter has been optimized with better cabling for better performance.

The EOS R10’s sensor offers a lower resolution at 24.2 MP, but it features the same Dual Pixel CMOS AF II technology as the R7 chip. Like the R7, while the basic sensor design of the R10 has been around for a while, Canon says the micro lenses and cabling have been revised to improve performance.

Overall, the sensors of both cameras are pretty equal. Both are APS-C format with 1.6x crop and native 3:2 aspect ratio. The EOS 90D offers more resolution, but the EOS R10 has larger individual pixels. That means it’s better in low light and at producing noise-free images. In addition, the sensor of the R10 is of a new design, which will benefit from recent technology.

The extra resolution of the EOS 90D, on the other hand, means you have more flexibility in cropping your images.


Canon EOS R10: 4K (3840 x 2160) up to 60p with 64% crop, 4K (3840 x 2160) up to 30p from 6K
Canon EOS 90D: 4K – 3840 x 2160 at 29.97, 25 fps

Like the R7, the Canon EOS R10 is capable of shooting 4K video at up to 60p, but this is subject to a 64% crop. This means that the lenses seem much longer than in photo mode. It is also possible to shoot 4K video at 30P downsampled from 6K footage and Full HD video can be shot at up to 120p. The maximum video recording time on the R10 is 2 hours.

The EOS R10 has a 3.5mm mic port, but it doesn’t have a headphone port.

Likewise, the EOS 90D is 4K compatible and captures the same angle of view in 4K mode (3180 x 2160) as in Full-HD and stills. The 90D’s 4K movies are shot in MP4 AVC/H.264 at 29.97.25 fps. The maximum duration is 29 minutes and 59 seconds while the maximum file size is 4 GB. You can also record videos in Full HD at 120 fps to create slow-motion movies.

Additionally, the EOS 90D has both a 3.5mm mic port and a headphone jack.

This category is close, but when we compare the Canon EOS R10 to the EOS 90D for video, we’ll give the R10 the edge for its faster 4K frame rate.

Auto focus

The Canon EOS R10 uses Canon’s Dual Pixel CMOS II AF technology and is sensitive down to -4EV. Like the R7, the EOS R10 also features Canon’s Intelligent Subject Detection System which can be set to seek out and focus on people, animals or vehicles. And if eye detection is enabled via the menu, the camera will prioritize the eyes of all detected subjects. This is a major advantage for people, pets and wildlife photographers.

The R10 also benefits from 4,503 AF positions and 651 selectable points.

As it is a DSLR, the Canon 90D has two AF systems. One is for use with the viewfinder (i.e. SLR mode) while the other works in Live View mode. The SLR mode system has 45 cross-type AF points with lenses that have a maximum aperture of f/5.6 or faster. Of those points, 27 work with lens and teleconverter combinations that result in a maximum aperture of f/8, and 9 remain cross-type. The center point is a double cross type with f/5.6 lenses.

Continuous shooting

Canon EOS R10: Mechanical shutter: 15 fps for up to 460 Jpegs or 29 raw files, Electronic shutter: 23 fps for 70 Jpegs or 21 raw files
Canon EOS 90D: 10 fps for up to 58 Jpegs and 25 raw files with UHS-II card with viewfinder, in Live View mode, up to 11 fps with One-Shot AF or 7 fps with Servo AF

Canon’s latest Digic X processing engine allows the EOS R10 to shoot at a maximum continuous shooting rate of 23 fps with the electronic shutter and 15 fps with the mechanical shutter. The faster rate with the electronic shutter is a major advantage of mirrorless technology.

The EOS 90D can take up to 10 fps with continuous autofocus when the viewfinder is in use. This throughput can be maintained for up to 58 JPEGs or 25 raw files when a UHS-II card is in the card slot. Alternatively, in Live View mode, the 90D can shoot at 11 fps in One-Shot AF mode or 7 fps in Servo AF (Continuous AF) mode.

Canon EOS 90D: Digic 8 processing engine

Although the Digic 8 processing engine is not that old, the EOS R10 has Canon’s new Digic X processor, which is much more powerful. With the Digic X engine, you can expect images from the R10 to have better color and less noise than the EOS 90D. It’s also much faster.


Canon EOS R10: 0.39-type 2,360,000-dot OLED EVF
Canon EOS 90D: Optics with pentaprism showing 100% field of view and 0.95x magnification

Some people love an optical viewfinder, but the EVF has come a long way. With a resolution of 2.36 million dots, the R10’s OLED electronic viewfinder is bright and will allow users to see what their image will look like with the exposure settings they dialed in.

Both viewfinders offer 100% field of view here, but the EOS 90D’s optical viewfinder offers higher magnification than the R10.

You can argue for both viewfinders here, but we’re guessing that feature won’t be a deciding factor when deciding between the Canon EOS R10 or EOS 90D.


Canon EOS R10: 2.95-inch vari-angle touchscreen LCD with 1.04 million dots
Canon EOS 90D: 3-inch, 1,404k-dot, vari-angle TFT Clear View II touchscreen

The EOS R10 and EOS 90D feature fully articulating touchscreen LCDs. This should appeal to vloggers or any photographer who enjoys shooting from unusual angles. Both screens here are roughly the same size, with equal resolution and touch responsiveness.

Like the viewfinder, your ultimate pick in this Canon EOS R10 vs 90D comparison probably won’t come down to this feature, but it does help illustrate just how well-matched these Canon cameras are.


Canon EOS R10: 122.5 x 87.8 x 83.4mm at 429g
Canon EOS 90D: 140.7 x 104.8 x 76.8mm at 701g

If size matters to you, it’s a clear distinction when comparing the Canon EOS R10 to the 90D. The R10 is around 30% smaller and 40% lighter than the EOS 90D.

In terms of looks, the EOS R10 is something of a mix of the Canon EOS M50 Mark II and a small DSLR like the Canon EOS 250D (aka the EOS Rebel SL3), with the addition of a joystick on his back. In fact, at 122.5 x 87.8 x 83.4mm it’s smaller than the 250D/SL3 – which at launch was the smallest DSLR with a moving screen and probably still is.

Additionally, at 429g including memory card and battery, the R10 is lighter than the 250D, making it a very portable and attractive camera for travel.

A point of note in favor of the 90D is its weather-sealed design. The EOS 90D is splash and dust resistant, unlike the EOS R10.

Overall, however, the advantage probably lies with the R10 for its miniature design.

Should I sell my Canon EOS 90D?

We have to admit we were surprised after doing this Canon EOS R10 vs 90D comparison just how well these cameras fit. They share a number of similar characteristics, and they’re quite comparable in where they differ.

With the EOS 90D, you’ll get more detail from your sensor (32.5MP versus 24.2MP), but the R10’s larger photo sites will deliver better color accuracy and less noise. Both cameras can shoot 4K video, but the R10 can do it at a more versatile 60fps – although it does so with a 64% crop.

But as long as it’s close, we’ll give the EOS R10 the lead. In addition to better video and faster continuous shooting, it’s considerably smaller and lighter, making it an everyday take-everywhere camera. This flexibility extends to minor features such as the ability to charge the camera via its USB port.

The R10 also benefits from innovations in mirrorless technology and technical advancements from Canon in the nearly three years since the launch of the EOS 90D. It’s faster and more powerful.

The EOS 90D is still a capable camera even after that amount of time. Whether you should sell it and upgrade it really depends on what’s important to you. We assume, however, that by investing in a versatile device like the 90D, you want a camera for all occasions. If so, the EOS R10’s miniature size and weight marks a significant upgrade in that department. This camera is so small that while calling it a pocket camera is probably a bit of a stretch, you could fit it in a coat pocket on a walk in the woods.
