[HOT] : Test Canon EOS R3 Part three

In other words, the Canon EOS R3 is more akin to a rival of the Sony A9 II, which has a 24.2 Mpx full-frame sensor, than the A1. And in a technical head-to-head, the EOS R3 comes out on top here.

Under very specific conditions, it can achieve a continuous shooting speed of 30 frames per second with AE / AF tracking using the electronic shutter – and maintain it for 540 JPEG files or 150 raws files (i.e. 18 seconds or five seconds of shooting).

In this 30fps shooting mode, it’s actually impossible to take just one frame – you can’t release the shutter button quickly enough. This means that you won’t want to run the EOS R3 at full throttle in more than a handful of situations. When the going gets tough and you just can’t afford to miss the photo – we think of the bouquet toss at a wedding, the moment the leopard comes out of hiding, the exact moment the sprinter crosses the finish line – the R3’s continuous mode leaves you dangerously short of excuses.

There are limits though – you can only achieve 30 frames per second if you use the R3 with its shutter set to electronic. If you’re attached to the haptic feedback and authentic “crackle” of a mechanical shutter, you’ll have to settle for 12 frames per second. There are other cameras with faster mechanical shutters, including the 1D X Mark III (16fps) and even the EOS-1D X Mark II (14fps).

Along with its ability to achieve staggering shutter speeds of 1 / 64,000th of a second, the electronic shutter can also sync with external flashes (up to 1 / 250th of a second) – something that was previously only possible ‘with mechanical shutters. Like Sony, Canon has similarly added anti-flicker and high-frequency shooting modes to help detect and correct for flickering from light sources.

Another big advantage over the Canon 1D X Mark III is the inclusion of image stabilization built into the body. When using the EOS R3 with compatible RF lenses, you get vibration reduction of up to eight stops. This allows you to preserve the quality of still images and, while it works as well as with the Canon EOS R5, get reasonably smooth videos without a gimbal.

We must also mention the autonomy of the device, because all these performances remain energy consuming. The datasheet says the R3 can only take 620 images using the viewfinder, or precisely 20.6 seconds of shooting at its maximum speed.

This point does not hold true. We capped at a higher meter in a single charge. But it’s entirely fair to say that during a demanding day of filming, you can expect the battery indicator to drift dangerously downward, to the point that you need a spare LP-E19 battery. at hand seems reasonable.

It is still relieving that, like the EOS R6 and R5, Canon has not introduced a new battery system. Therefore, if you already have an EOS-1D X Mark II or Mark III, you already have a compatible battery. This is just as factual for any Canon body dating back to the EOS-1 Mark III (2007). Also, there is a fairly wide choice in terms of new batteries, used units and inexpensive third-party units to extend your photo sessions.

As the Canon EOS R3 is designed for professional sports photographers, it also relies on connectivity. In addition to Bluetooth 5.0 and 5Ghz Wi-Fi, you also have a Gigabit Ethernet port for image transfer via FTP servers. EOS R3 owners will also be able to use Canon’s Mobile File Transfer (MFT) application to transfer images to remote servers via their smartphone or tablet.

This application will combine perfectly with a new accessory, the Smartphone Link AD-P1, which will invite you to mount your iOS or Android smartphone on the optional multifunction shoe. While most of these features will be overkill for the amateur photographer, agency photographers will certainly appreciate the EOS R3’s generous connectivity.

Photo and video quality

  • Incredible images at high ISO
  • Fantastic dynamic range with beautifully balanced colors
  • Records oversampled 4K / 60p video and 6K / 60p raw video internally

It’s fair to say that if you own an EOS R5 or R6 and want to improve picture quality, the EOS R3 doesn’t exhibit good value for money. Its 24MP full-frame stacked CMOS sensor is, by all accounts, an excellent sensor. But if a revolution in dynamic range and low-light performance is possible, it still has everything to prove.

This does not mean that the images are not of good quality; they turn out to be fantastic. Canon’s legendary mastery of color processing is evident, and the R3 returns a well-balanced, good-quality set of images. It’s also amazing when it comes to low-light photography – compared to the EOS R5, it adds an ISO step at the top end, jumping up to ISO 102,400.

A series of test images (above) confirmed what our field evaluation suggested: ISOs up to 1600 are indistinguishable; push it up a notch to ISO 3200 and you’ll see every trace of noise creeping into areas with no detail. Go ahead and ISO 12800 produces a fine grain, cinematic look, but it’s really only around ISO 51200 that you will see more hazy looking noise in your footage.

We would say, however, that images at this setting are quite usable, making the R3 a potential champion for press photography, astrophotography, bad weather sports, good weather sports or weddings. It’s a device you can use to the end of your life and be sure to produce reliable, usable images at ISOs that would have been unthinkable, if not unachievable, five years ago.

Canon has been relatively quiet about the video capabilities of the EOS R3, and yet they have everything to shine. This is a powerful hybrid device that can, unusually, record raw video internally (at 6K / 60p, using the full width of the sensor) and 4K / 60p oversampled video.

The advantage of oversampled video is its tendency to detail and noise reduction. Our exhibition video shows a very well controlled rolling shutter, thanks to this new stacked sensor, although it is not impossible to see the effect if you move the camera very quickly.

When shooting in 6K raw format, you can opt for CRM (Cinema Raw Light) mode, which helps produce relatively manageable file sizes without compromising dynamic range. Calibrators will also be happy to see C-Log 3 format support for malleable 10-bit files, while the overheating issues that plagued the Canon EOS R5 prior to the firmware update turn out to be rarer with the release. ‘EOS R3.

This is partly due to the fact that there is more space available for all of the components in the R3’s body, and also because of its lower resolution sensor. Canon claims you’ll be able to shoot for six straight hours (assuming you have enough juice) at standard frame rates, and up to an hour and a half in 120p mode.

You have the option to record videos simultaneously to CFexpress and UHS-II locations to create a backup. The video credentials of the EOS R3 are further enhanced by the new multi-function shoe, which can power accessories like the new directional stereo microphone DM-E1D.
