[HOT] : Test Canon EOS R3 Part two

As a mirrorless camera, there are naturally a few differences between the Canon EOS R3 and the company’s sports DSLRs. The two most obvious are the viewfinder and the rear screen. Canon has confirmed that the EOS R3 has the same electronic viewfinder (EVF) as the Canon EOS R5, that is, a 5.67 million dot viewfinder with a refresh rate of 120 fps.

Canon claims that it “rivals optical viewfinders”. In practice, it turns out to be indistinguishable from the two. Canon has also added an “OVF simulation View Assist” mode, which allows you to see the action unfolding outside the frame.

Something more unexpected is the 3.2-inch variable-angle touchscreen with a resolution of 4.1 million dots. It outperforms the Sony A1’s 1.44 million-dot tilting rear screen, and its full articulation feels especially handy for videographers. It’s also 0.05 inch larger than the screens of the 1D X Mark III or the EOS R5, which you won’t notice … except that it focuses almost twice as many pixels – and that’s it. remarkable!

This is, in fact, the first variable-angle display we have handled on a camera that meets Canon’s professional standards. It therefore seems resistant, not to mention that it offers you the possibility of turning it over so that it is well wedged against the case of the R3 when you put it in a backpack. It’s also a big evolution from the completely rigid rear screen of the Canon EOS 1D X Mark III.

A new feature that we haven’t seen on any other Canon camera so far is the new multi-function hot shoe in the middle. It’s interesting because, like Sony’s multi-interface hot shoe, it enables high-speed two-way data transfer between the camera and any compatible accessory mounted on it.

Canon has announced the launch of a Directional Stereo Microphone (DM-E1D) and Speedlite Transmitter (ST-E10), both of which are fully compatible with the EOS R3’s hot shoe (which can power them). The hot shoe displays the same size as Canon’s standard hot shoe, so you can pair all your old accessories with it.

Autofocus

  • New Eye Control AF is more than just an extra
  • AF tracking now targets vehicles, in addition to humans and animals
  • Aim at any subject with impressive speed

In the great war between Sony’s mirrorless cameras and those of Canon, the battle is often won over the quality of the autofocus – and that of the EOS R3 is clearly breaking new ground in Canon’s favor.

Before talking about our real experience, let’s present the strengths of this autofocus. Like the Canon EOS R5, the EOS R3 features the Dual Pixel CMOS AF II system, with a few distinctions. Canon claims the EOS R3 is “the fastest EOS R-series camera to date” in terms of focusing, beating the R5 with its ability to focus in 0.03 seconds, against 0.05 seconds.

The EOS R3 is also the first Canon camera to feature “vehicle-tracking” autofocus mode. We’ve seen this mode on the Olympus OM-D E-M1X before, and the R3’s works in a similar fashion, with an Intelligent Subject-Detection AF system locking focus on rally cars, motorcycles and cars. F1 racing cars with open cockpit. This so that you can concentrate on the composition.

In practice, we’ve never been disappointed – in fact, the autofocus is almost impossible to fool. We’ve been saying this for some time now about professional-grade cameras, but whether in poorly lit, heavily backlit, low-contrast, or dynamic situations, the EOS R3 tracked our subjects incredibly effectively.

We tested it with Canon’s 24-105mm f / 4L and 70-200mm f / 2.8L RF mount, and both of these current generation lenses produced crisp shots. If you’re shooting sports or wildlife, the EOS R3 gives you razor-sharp images. While people tracking is an obvious inclusion, as is animal and vehicle tracking, the most unique aspect is represented by the brand’s AF Eye Control.

Although it looks futuristic, it is actually a new version of the “eye-controlled autofocus” system already worn by the Canon EOS 3 SLR in the late 90s. It allows the camera to detect the targeted area in the viewfinder and move the autofocus to that point on the frame. The goal is to capture the fastest scenes without wasting time manipulating the manual controls. The option will allow you to make the most of this time by focusing on adjusting the exposure or composition. According to Canon, the system was adapted from technology used in the company’s medical division. It harnesses eight low-power LEDs to let the viewfinder faithfully follow your eye and overlay that information onto the sensor.

We are pleased to announce that the Eye Control AF Selection is much more than a gadget. You can configure it in different ways, but the end result just looks stunning.

When the camera chooses its own focus points, it can select them anywhere in the frame; if you opt for manual focus point selection, you can choose between 100% of the frame width or 90% of the verticality. A total of 4,779 different focus points are available in still mode (this figure drops slightly to 3,969 in movie mode).

Compared to the Canon EOS R5, the AF performance is slightly better in low light. Canon claims that the EOS R3 can focus in lighting conditions as low as -7.5 EV (think of a night scene with minimal lunar reflection) – which is a definite improvement over to the low value of -6EV indicated by the EOS R5. Keep in mind, though, that both of these numbers are based on shots with an f / 1.2 lens at ISO 100, so we’re getting more of a theoretical ceiling than a practical reality.

Overall, then, no camera gives you more options for controlling your autofocus than the EOS R3. Between the Smart Controller, the touch screen, the autofocus joysticks and the Eye Control AF, it is impossible to miss your focus.

Main features and performance

  • New 24.1MP stacked CMOS sensor
  • Continuous shooting at 30 fps (raw or JPEG), with electronic shutter
  • Continuous shooting at 12 fps, with mechanical shutter

Our succinct review of the performance of the Canon EOS R3 is “breathtaking”. The long version requires a bit of context. The most important feature of the Canon EOS R3 is its new 24.1 Mpx sensor. The company’s first “stacked” model.

Sony is the pioneer of full-frame “stacked” sensors, whose layered structure allows more complex circuitry to be integrated behind photosites. The result ? Faster data read speeds, which offers advantages such as faster continuous shooting speeds and a reduction in the “rolling shutter” phenomenon in video. This also applies to the EOS R3.

In a world where the Sony A1 is capable of shooting 50MP photos at 30fps, the EOS R3’s 24.1MP resolution may seem underwhelming. But unless you regularly crop your photos, this resolution is more than good enough for most photographers.
