Canon Mirrorless Camera EOS R

Canon Mirrorless Camera EOS R – A Winner?

Canon Mirrorless Camera EOS R is the new flagship model of the Japanese giant unveiled to rival the mirrorless models of the likes of Sony, Fujifilm, and Nikon. We are here to see if it’s really winning over the competition it is brought forth for. 

Call it a miracle out of nowhere or a proof of concept announced out of proportion, the Canon Mirrorless Camera dubbed as EOS R is finally here. It almost seems as 2018 has been ringing for Canon to bring out something innovative. The camera is what it is announced to be and its features sway a little bit away from its predecessors. We’ll find about that in a minute. 

Along with the camera, Canon has launched three lenses also called EOS R. We are talking about RF 35mm F 1.8 Macro IS STIM, RF 24 – 105mm f/4 L IS USM, and the RF 50mm F 1.2 L USM. Both of these lenses have their own capabilities and they differ from the EF lenses in having a control ring, which is a kind of redundancy. 

Nevertheless, the lenses are quite compatible with the camera and why shouldn’t they be – they are built for it, after all. This goes to say that you can’t mount EF lenses on the camera until you have dedicated lens mounts sold separately. We’d get to this also, but first, let’s summarize key features. 

Key Features 

Image Sensor 

Canon Mirrorless Camera EOS R boasts a sensor of 30.3MP, which is quite the size of the one possessed by EOS 5D Mark. However, what is different between the two is that the EOS R has a detection system with an impressive 5,655 focus positions. 

Another difference is that the new flagship has something which the EOS 5D Mark doesn’t have – the Digic 8. It’s a quality processor much revered by the community for godly performance. 

This also gives us reasons for the increased ISO. You can go from 100 to as far as 40,000, but the show does not stop here. The maximum expendable capacity of this can even be increased to 102,400, although it is highly unlikely for anyone to use that much of an ISO. 

When it comes to burst shots, you can only shoot up to 8 frames per second, but there’s a catch. All of the frames seem to lose their minds and go out of focus when on burst mode. So to say, for a camera of this caliber, this is a little disappointing. 

What Canon has done so far with the image stabilization is also disappointing. There is none of it on the sensor, which is quite odd considering its competitors, Sony and others, have it in-camera. But all is not lost because it comes with a digital IS, instead. You can use that, but keep in mind that you’ll image will go through a pretty heavy crop. Who wants this, anyway?

Besides that, you’d want to have the image sensor of your camera to be protected from the elements. While most of the mirrorless cameras do not have anything to do that, Canon’s EOS R does have something up its sleeves. When you turn off the camera to remove the lens, a small shutter comes down to protect the sensor from being exposed to dangers. 

Lens mount 

Here, too, we feel the lens mount is same as the EF mount. However, no matter how much you try, you still won’t be able to use them directly or natively on the camera (Canon has something going on here). 

Yes, the RF lenses can be very compatible with the mount, but for the EF lenses, you’d have to use three separate mounts. One is called Mount Adapter EF-EOS R, the other one Control Ring Mount Adapter EF-EOS R, and the third one is called Drop-In Filter Mount Adapter EF-EOS R. 

As the names of the mounts go, they have different capacities. The first one is just a basic adapter, the second one is a bit complicated with the adjustment ring thingy, and the last one has a slot for filters. This ultimately means each of them has different prices in an ascending order from first to last (we hope we don’t sound too much technical). 

That also means quite of a work for a photographer. To switch between the two lenses, you’d have to first unload the EF lens, then the mount, and then load the RF lens and vice versa. So, if you’re expecting to be all-in-all with this piece, you’d have to somehow learn to do that faster.

View Finder 

Mirrorless cameras come with electronic viewfinders (EVF), and Canon Mirrorless Camera EOS R is no different. Equipped with 3.69 Million Dot OLED EVF, the camera does quite good in giving you live previews of the shots and scenes you are to capture while tweaking the exposures. 

If you think that’s the best thing about the EVF, then know that it does not allow any blackouts when you are in the burst mode, although the shutter does it work to capture multiple images at once. 


We mentioned the RF lenses that come with this model and the Control Ring they flaunt. What does the Control Ring do, you ask? Well, it controls pretty much everything from shutter speed, ISO, and even aperture. For anyone who’s keen on tweaking these things in stills and videos, the Control Ring could be a blessing. Other than that, as we said, it’s redundant in most cases. 

All of the lenses do well in certain conditions and so, you cannot expect to create magic with only one lens in every situation. For example, the RF 24 – 105mm f/4 L IS USM shoots crisp black and whites, but if you’re into shooting portraits to get a detailed picture of the object, you’d have to go with the RF 50mm F 1.2 L USM because it allows you to drop ISO without compromising on the quality of the image. 

SD Slot 

Following the suit of Canon EOS Mark II, the Canon Mirrorless Camera EOS R has only one SD card slot. However, the latter model has been blessed with an updated UHS-II instead of UHS I in the former. 

If you can go with only one slot, then the camera shouldn’t pose any problem. But in situations where you’d have to shoot redundant, it could pose as a limiting factor. 


One of the striking features that the model in question comes with is its autofocusing points. There are 5,655 of them. 

Looking at that number, expectations must have you think that the camera would return bright imagery, but that’s not the case. This is because you cannot select any individual focus point out of the 5,655. However, you can control the size of the box and they cover the whole of the viewfinder with a one box space to either side. 

In all of this area, you have the freedom of selecting any focus point to let the camera know which area you want to bring into the limelight. 

In low-light, up to EV -6, you can easily focus your shots, but for that, you’d have to use F1.2 lenses and keep the auto-focus point in the center. 

LCD Screen 

Unlike the 3.2 inch screen on most cameras, Canon Mirrorless Camera EOS R has only 3.1 5” 2.1 Million Dot Vari-Angle Screen. The “vari-” in the name alludes to the fact that you can rotate it in various angles without breaking it. So, for anyone who’s into vlogging or self-recording, this could work a whole lot better. 

Apart from giving you live previews of your shots, it also can be set to “touch and drag AF”, which you can set to anywhere on the screen. No, there’s no AF control where you’d normally find it. You’d have to resort to the settings in the LCD.

Silent Shooting 

Silent shooting can be required in some situations and if that’s the case, the camera does not do well than the other models in the market. You see, there’s no continuous shooting while shooting this way. You only get one frame per shot and to capture another one, you’d have to press the shutter again. 

Canon promises to release a firmware in near future that will enable continuous shooting. Until then, you’ll have to go with the single shot mode, which tells you to shoot again by showing a white frame every time you take a photo. 


Canon Mirrorless Camera EOS R has satisfying ergonomics – the one you’ll find in any DSLR. Due to this, the camera can be carried around and held quite easily. 

It inherits weather-sealed body just like the 6D Mark II and weighs about 1.46 lbs or 660 g, which again is something similar to that of the Mark II and Sony’s A73.

Our verdict 

Canon has done absolutely fantastic by launching their own mirrorless version, the Canon Mirrorless Camera EOS R. It has some seriously good features like the Control Ring and auto-focus points, but there are some areas where it still needs to work. Take burst shooting as an example that lags behind in silent shooting or its restricted fps or a lack of image stabilization. So, considering everything all in one go, we’d say that for starters, the camera is not that bad, but Canon would have to do better in their next mirrorless model. This ultimately puts this model behind its competitor, unfortunately.
