Canon EOS R100 vs Canon EOS R10 - Which is Better?
The entry-level EOS R100 and EOS R10 cameras were released within 6 months of each other as Canon seeks to dominate all areas of the mirrorless market, but which camera should you choose?
We're bringing you this in-depth head-to-head comparison between the new Canon EOS R100 and its more expensive sibling, the EOS R10, to find out what the key differences are between them.
You can also read our detailed Canon EOS R10 review to find out exactly what we think of that particular camera.
The Canon R10 has a more advanced 24.2 megapixel APS-C CMOS sensor which is partnered with the very latest Digic X processor.
The new Canon R100 also has a 24 megapixel sensor, but it's an older model that's been inherited from the EOS M50 Mark II and "optimised" for the R100.
The R100's 24.1 megapixel sensor is different to the one found in both the R50 and R10, and it's also paired with the older Digic 8 processor.
Subsequently the image quality for both stills and video will be better in the R10 than the R100.
On the Canon R10 the ISO range for stills runs from 100-32,000, which can be further expanded up to ISO 51,200, exactly the same as the EOS R50.
The R100 has a slightly more limited ISO range of 100-12,800 which can be expanded up to 25,600.
The EOS R10 can record up to 4K UHD / 30p / 10-bit footage internally with dual-pixel auto-focus and auto-exposure.
The new R100 also offers 4K video, but only at 25 frames per second, and it still suffers from the same heavy 64% / 1.55x crop as the EOS M50 II, which really makes it a high-quality 1080/60p camera rather than a 4K one for the majority of users.
The R100 also doesn't support the additional 4K/60p mode offered by the R10, although that also suffers from a 64% crop which gives a frame similar to Super 35mm.
Also note that on the R100, autofocusing during 4K recording is only contrast-based, which is slower and less precise than the phase-detection system that operates in the camera's 1080p mode.
The R10 offers full 1080 slow-motion recording at up to 120p with autofocus (but no sound), plus live streaming on YouTube and vertical video capture.
The R100 also provides 120p slow-motion recording but only at 720p resolution. It also supports vertical video capture, but not live streaming.
Recording time is limited to 2 hours on the R10 and just 30 minutes on the R100.
The R100 offers Movie Digital Image Stabilisation (IS), an extra Digital IS mode called Enhanced which helps to keep handheld footage sharp.
The EOS R100 can be used as a webcam simply by connecting it to a computer with a USB cable, whereas with the R10 you have to additionally install the EOS Webcam Utility software in order for it to be recognised.
The R10 has a much more advanced auto-focus system than the R100.
It features the the same deep-learning artificial intelligence based automatic face, eye, animal and vehicle AF tracking modes as the much more expensive full-frame R3, R5 and R6 models.
This AF system has 651 automatic focus points and 4,503 manually selectable AF points, 100% frame coverage in Auto selection mode and 90% vertical and 100% horizontal in manual selection.
The R10 can recognise and track eyes, and it works even if the person is wearing a mask, helmet or sunglasses. Subject tracking works for humans and also dogs, cats and birds, the latter even in flight.
It also has the ability to track vehicles, including cars and motorbikes. What's more, if the driver is wearing a helmet, the AF system will lock on to that, ensuring that the most important subject is in focus.
The R100 has a less sophisticated autofocus system that offers face and tracking AF with eye-detection.
It's shame not to see any animal or even bird eye-AF added too, although that's probably to be expected on an entry-level camera like this one.
The R10 can focus in light levels as low as -4EV (when used with an F1.2 lens) or with maximum apertures as small as f/22, which enables autofocus even when using ultra telephoto lenses with teleconverters.
The EOS R10 can shoot at 15fps when using its mechanical shutter and 23fps when using the electronic shutter, both with continuous auto-focus and auto-exposure.
The R100 has a much slower burst shooting rate of 3.5fps with full-time AF/AE and 6.5fps without. Both models offer a completely silent mode.
If you shoot a lot of sports, action or nature photography, the R10 would be a much better choice because of its faster burst rates.
Body and Design
The design of these two cameras is quite different. The R100 is significantly smaller and lighter than the R10. It's actually the lightest and most compact full-frame camera that Canon currently offer
The R100 measures 116.3 x 85.5 x 68.8mm and weighs in at just 356g with both a battery and memory card fitted.
The R10 measures 122.5 x 87.8 x 83.4mm and weighs 429g with both a battery and memory card fitted.
Due to rather its diminutive stature, the Canon R100 does suffer from having a shallow handgrip that only just accommodates three fingers. If you have large hands, the R10 would be a better choice thanks to its much deeper grip.
The main downside of making the R100 smaller is a marked reduction in the number of external controls. There's only one command dial and no M-Fn, Lock or AF On buttons or an AF joystick as on the R10.
The R100 has a larger D-pad than the R10, perhaps because it doesn't offer a touchscreen LCD.
Turning once again to the negatives, the R100 has the older 5-pin hotshoe, not the more sophisticated multi-function shoe that the R10 and all other recent Canon mirrorless cameras have.
Neither camera has an in-body stabilizer, only providing digital IS for movies in-camera.
Instead you have to rely on a mix of lens stabilisation (if the lens offers it) and/or in-camera digital stabilisation.
So if IBIS is a must-have feature for you, you'll need to look further up the Canon range.
Both cameras have exactly the same integrated OLED electronic viewfinder with 2.36M dot resolution and magnification of 1.15x.
The one on the R10 has a faster 120fps refresh rate whereas the R100 is limited to 60fps.
The Canon R10 has a 3-inch, 1.04 million dot, vari-angle LCD screen which tilts out to the side and faces forwards for more convenient vlogging and selfies with a touch-screen interface.
The cheaper R100 model also has a 1.04 million dot, 3-inch screen, but it's fixed in place. Yes, you read that right, the R100's screen cannot be moved or tilted or rotated in any direction.
And that's not the only throwback to cameras of yesteryear - the R100 doesn't have a touchscreen either, unlike the R10 and all other current Canon mirrorless cameras.
This is particularly perplexing on a camera that is aimed at people looking to upgrade from a smartphone.
The EOS R10 supports SD memory cards via its single UHS-II SD memory card slot.
The R100 also supports a single SD card, but only the slower UHS-I format.
The R10 uses exactly the same LP-E17 unit found in lots of previous Canon DSLR and mirrorless models like the 850D and 250D.
The R10's battery life is 430 shots with the LCD and 260 with the EVF.
Both cameras feature built-in Bluetooth and Wi-Fi and can be easily connected to a smartphone and networks allowing high-speed file sharing and FTP/FTPS transfer.
Note that the R10 supports both the both 2.4Ghz and faster 5Ghz wi-fi speeds, whereas the R100 only supports the slower protocol.
Both models can be remotely controlled and even updated using Canon's Camera Connect and EOS Utility apps.
Live streaming to YouTube is supported on the R10 via wi-fi and Canon's image.canon service, but not on the R100.
The Canon EOS R100 is priced at £669 in a kit with the Canon RF-S 18-45mm F4.5-6.3 IS STM lens. There is no body-only option.
The Canon EOS R10 is priced at £899.99 / €1079.99 / $979.99 body only in the UK, Europe and USA respectively. It is made in Japan.
The new Canon EOS R100 is the smallest, lightest and cheapest model in the extensive range of R-series cameras, with an even more pronounced focus on beginners than last year's EOS R10.
It does lose out to the R10 in most regards though, most notably image quality, video capability, burst shooting speeds and auto-focus performance, not to mention the rather perplexing fixed non-touch LCD screen.
