Canon EOS R review (A Decent Mirrorless Camera)

Canon has been dominating the photography world since the beginning. The Canon EOS R is another mirrorless invention from Canon. In this article, You will find an in-depth Canon EOS R review and I will share every single experience that I have with this camera.

2018 was a big year for mirrorless cameras with Nikon, Canon, and Panasonic. All the big companies came up with this new idea of making cameras mirrosless.

Canon’s first Mirrorless camera was “Canon EOS M”, but it wasn’t up to the mark.

But in 2018 Canon comes with Canon EOS R that changes the whole experience of every photographer and videographer like me.

In my opinion, Mirrorless technology in the future of the camera world and It was very tough for Canon to put enough time and resources into making a high-quality Camera system that can replace their EOS DSLRs.

When Canon released their EOS R, the first accessory available was the canon mount adapter EF-EOS R.

By using this simple Adapter you can use all Canon EF, EF-S and TS-E lenses on RF mount cameras.

Another two adapters are the EF-EOS R Control Ring mount adapter and the EF-EOS R drop-in filter adapter.

The Canon EOS R obviously has both pros and cons. The EVF is great, the autofocus is excellent, and the customization options are powerful.

On the downside, the ergonomics leave a bit to be desired, and the single card slot may be a deal-breaker for some.

I will not give only my opinion about the camera. I have researched quite hard for reviewing this amazing product and I will write everything that I have found relevant with my experience.


A full-frame conservative mirrorless camera that boasts crisp 30.3 MP Imaging. It begins the journey of RF-mount lenses. You also have to make compromises like a single memory card slot and the cropped 4k. A successful entry in the rapidly growing team of full-frame mirrorless cameras.

Canon EOS R review: KEY FEATURES

canon eos r image quality

This mirrorless camera comes with 30. 3 Megapixel Full-frame CMOS Sensor and DIGIC 8 Image Processor.

 The EOS R features a detection system with the Dual Pixel CMOS AF with 5, 655 manually selectable AF points, which cover 88% of the frame horizontally and 100% vertically.

You can shoot 4k videos with 30P with Canon log.

The 3.69 million-dot electronic viewfinder and 3.15-inch, 2.1 million-dot articulating touchscreen both remain more than serviceable.

It’s Expanded ISO 50-102400, 8 fps Shooting is pretty much up to the mark.

Like Nikon with its new Z range of full-frame mirrorless cameras, Canon has opted for a replacement lens mount for its R range of mirrorless cameras.

The new RF mount shares an equivalent throat diameter of 54mm as Canon’s EF lens mount but features a considerably shorter flange distance.

This has dropped from 44mm to 20mm, though it is a little longer than Nikon’s Z mount flange distance of 16mm.

As you’d expect, you will be ready to use your Canon EF lenses on the EOS R via an adapter, but instead of launching one variant, Canon’s launching four different adapters.

Until all of about five minutes ago, most mirrorless cameras were easily distinguished from DSLRs. FujiFilm’s X-series models, Sony’s A-series clan, and Canon’s own M models all have skinnier bodies and grips than traditional DSLRs.

It makes sense: mirrorless cameras are meant to be smaller, more portable.

They’re the type of camera you would possibly combat holiday or for a walkout with the family, where fixing an attempt on a tripod for half an hour wouldn’t go down well together with your fellow travelers.

The Canon EOS R looks and feels tons sort of a DSLR. It’s smaller than the Canon EOS 5D Mark IV, closer in scale to Canon’s APS-C sensors models.

However, it’s immediately clear that creating the EOS R as small as possible wasn’t top of the design planning priority list. this is backed up by its initial lenses too.

The kit lens, a 24-105mm zoom with constant f/4 max aperture, isn’t compact or light. this is often probably not a set-up that will encourage you to take your camera out more often.

If the innards fall somewhat in need of expectations, the EOS R’s exterior unquestionably exceeds them.

The magnesium alloy body screams “quality”, feeling as robust because it does fantastic to carry. As you’d expect, it’s dramatically more svelte than its DSLR cousins; where the 5D Mark IV may be a thick-cut oven chip, the EOS R maybe a french fry.

This does, of course, lead to the inevitable situation where larger lenses feel unbalanced on the smaller body. 

Whichever RF lens you decide for, ahead of the manual focus ring you’ll notice a further input: the Control ring.

This will be programmed to regulate aperture, shutter, white balance, or ISO, offering an additional dimension of control and customization.

Videographers, as an example, will jump for joy at the power to possess a cinema-style aperture ring. This input also can be added to any EF or EF-S lens with the Control Ring Mount Adapter.

The EOS R features ‘Touch and drag’. this permits you to use half the LCD together big trackpad once you look around the EVF, dragging your thumb across the screen as you’d a joystick to pick your focus point.

Again, the dimensions and stretch of your paws will dictate how elegant an answer this is often for you, but we had no problems gliding across the 5,655 focus points.

Unlike other mirrorless cameras, removing the lens shouldn’t expose the sensor. When the facility is transitioned, the focal plane shutter curtain covers the sensor, protecting it from both light and mud particles.

Don’t change lenses with the camera powered-up as this retracts the shutter curtain, exposing the sensor.

The reduction from a 44 mm flange back distance within the EF mount system to the 20 mm of the new RF mount provides scope for brand spanking new lens designs that employ large diameter elements on the brink of the image sensor.

These new lenses should provide better control over optical aberrations, particularly towards the sides of the image frame.

Is the Canon EOS R good for video?

Canon eos r camera review

The EOS R is the first Canon camera capable of using Dual Pixel autofocus while capturing 4K video. While this means that it’s going to be easy for users to capture in-focus video, there are a lot of other factors to consider.

The EOS R is subject to an equivalent rather extreme crop when shooting 4K that the older EOS 5D Mark IV exhibits.

Although you’ll certainly find lenses – particularly EF-S lenses meant for the company’s crop-sensor DSLRs – which will allow you to shoot at fairly wide angles with the EOS R, this is often a specific problem for stills and video hybrid shooters.

Having to vary lenses once you move from stills to video just isn’t practical for several people.

And though we found that the color output from the EOS R is basically pleasing, Smooth, and vibrant.

Without an in-body stabilizer, it is often difficult to urge smooth hand-held footage and keep your horizon straight, even with a stabilized lens.

The rolling shutter is basically noticeable. The digital image stabilizer softens output and causes artifacts within the corners of your footage.

One plus side that I have found that the battery life while shooting video to be a robust suit.

If you would like to ramp your aperture up or down, it does so smoothly. you’ll use Auto ISO with exposure compensation in manual movie mode, so you’ll dial in your shutter speed and aperture as you wish and have the camera gain up or down counting on the lighting. 

you’ll capture video internally at very high bitrates, and you’ll output 10-bit Log footage, allowing you to form the foremost of the camera’s dynamic range.

It’s worth noting that, with its 1.8x crop in 4K mode, the EOS R is nearer to being an APS-C/Super 35 camera than a full-frame one.

It uses a sensor area most similar to that of Panasonic’s GH5S. This is an important context to keep in mind for depth-of-field and low light performance expectations.

The EOS R’s 1080p output looks fairly competitive against the Nikon Z7 and offers slightly better detail than the Sony a7 III, but the Fujifilm X-T3 continues to lead the pack and is using a larger sensor region than the Canon, so is likely to perform better in low light.

Is Canon EOS R good for landscape photography?

It has a variety of textures, colors, and detail types you’ll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.

I have an in-depth article on 10 best Camera for beginner nature photography

The Canon EOS R features a 30.3-megapixel full-frame sensor, reportedly one supported the sensor utilized in the Canon EOS 5D Mark IV.

The base ISO is 100, and therefore the native ISO range tops out at 40,000. this will be expanded right down to ISO 50, and up to 51,200 and 102,400 in absolute emergencies.

As you’d hope from a full-frame camera with a sensor almost like that of the 5D Mark IV, the Canon EOS R gives you masses of scope to tug seemingly non-existent detail out of shadow areas of a picture. That’s without the image-ruining noise or contouring you’d see after doing so with a smaller sensor camera.

According to me, if you keep the ISO to 1600 or below then you can maintain the post shoot edit flexibility.

The noise performance of this camera is really worked well for me.

ISO 12,800 is the most upper limit of what I would want to shoot regularly.

The Dynamic range is also good enough, although the Canon EOS R doesn’t give you the same flexibility level like Sony and Nikon.

You can still recover a decent amount of detail in the shadows and preserve highlight detail, in post-processing.

I always love the color reproduction of Canon Cameras, and the EOS R delivers the same.

You will see nice, natural tones, with skin tones faithfully reproduced too.

The EOS R’s metering system also works well, delivering well-balanced exposures, while there are no nasty surprises when it comes to the camera’s auto white balance system.

There’s a choice of either Ambience or White priority auto settings, with the latter delivering neutral images even under tungsten lighting, while Ambience priority has a bias to retain some warmth in the image.

Pretty good performance for its class with generous buffer depths, but slow buffer clearing.

It takes around 2 seconds to turn on and capture a shot and it takes around 1 second to turn on and record the first video shot.

The powerup system was sluggish compared to DSLRs, and a bit slower than other mirrorless cameras that I have experienced with.

Switching from play to record mode and taking a shot was faster but obviously slower than most DSLRs.

The Canon mark 5D IV powered up and took a shot in about 0.5 second.

In terms of the Canon R’s ability to work out that it’s properly focused when shooting an equivalent target multiple times, its full autofocus shutter response was quite good for a mirrorless camera, and competitive with most prosumer DSLRs.

Using the Canon RF 24-105mm f/4 kit lens, we measured 0.111 seconds for full AF lag using single point (center) AF-S with the default electronic first curtain shutter (EFCS) mode, which is sort of fast.

Shutter lag using manual focus was also quite good compared to other mirrorless cameras. When “prefocusing” the camera by half-pressing and holding down the shutter button before the ultimate exposure, the EOS R’s shutter lag was quite low, at only 52 milliseconds.

To minimize the effect of various lens’ focusing speed, I tested AF-active shutter lag with the lens already set to the right focal length.

How long does the EOS R battery last?

canon eos r battery

When buying a camera, people obviously look at the battery life.

That’s why EOS R battery life is also a concern for photographers who are willing to buy.

This camera can take 370 shots on a single LP-E6N.

But this is not same in DSLRs, you can take much more shots than EOS R with a single LP-E6N.

But while using the camera, I have found the battery life to be much better than the specification.

I have took the EOS R as a trial for a shooting. Over the event I was able to shot 720 Shots with the EOS R without changing any batteries.

I am not sure that this number will remain the same to you. You can able to take much more shots than me.

I know some of my friends had been able to take 1158 shots with a single battery. So, according to me, the battery life of Canon EOS R does a great job as a mirrorless camera.

Canon EOS R Review: Lenses

canon eos r vs r5

The introduction of the EOS R brings with it a replacement lens mount, necessitated by the much shorter distance between the lens mounting flange and therefore the sensor itself, a feature of all mirrorless cameras. 

This is often an honest thing – the closer the rear element of the lens is to its sensor, the less refraction you get, and therefore the better images will be at their edges.

The ‘kit’ lens – and therefore the most rational choice for first-timers – is Canon’s RF-mount 24-105mm f/4 lens. It’s an excellent walk-around little bit of kit, with a wise amount of zoom and integrated image stabilization.

It’s also incredibly sharp, producing pro-quality images at every aperture.

There’s the 10x zoom 24-240mm f/4-6.3, for instance, an excellent travel zoom, while portrait photographers will find themselves magnetically drawn to the 85mm f/1.2 short telephoto.

The 35mm f/1.8 may be a lovely little macro lens – small, light (305g), and quick.

It’s fixed wide-angle focal distance makes it less of a natural choice but its ability to focus close gives it a stimulating blend of utility and novelty.

Compared to other systems, Canon’s native choices for its RF mount put it on-par with most other systems – Nikon offers an identical number of lenses and, just like the EOS R, provides a reasonable FTZ mount to permit to suit legacy glass.

Sony offers a striking number of lenses for its Alpha system, and sports professionals should note the recent arrival of lenses like its 400mm f/2.8, 600mm f/4, and 200-600mm f/5.6-6.3.

Should I go for the Canon EOS R?

The EOS R is revolutionary because it shows how your pictures will come out before you take them.

The EOS R remains a self-assured entry into the full-frame mirrorless marketplace for Canon.

It’s almost a professional camera, although a couple of its recent firmware upgrades – autofocus tracking in its eye-detection mode and continuous shutter release while using its silent shutter focus – will definitely elevate it within the eyes of a couple of pros, wedding photographers not least among them.

For hobbyists, it will be a great product to buy, and its compatibility with not just Canon’s new range of RF-mount lenses and its legacy EF-mount glass is going to be the icing on the cake.

Competition, not least from Nikon and Sony, remains stark, though, meaning those that aren’t already bought into the Canon family have a really tough option to make.

Still, there are tons to love here, though, including good handling, an incredible electronic viewfinder (the best on any Canon camera), and a comprehensive autofocus system.

Mirrorless cameras, in general, are known for their ability to work well in low light and the EOS R is no different.

If you ask the question to me, If I was in your place, should I buy?

So the topic “canon eos r review” comes to an end. I have shared as much as I know and I have tried my best to gather information from the Internet as well. Yes, I would love to buy this camera as a photographer and videographer.
