EOS World Council Member Barry Seah is a professional commercial and studio photographer. In this article, he gives us an in-depth review of Canon’s latest Canon EOS R and Canon EOS RP.

I was honoured to be given an opportunity to try out the Canon EOS R and Canon EOS RP for my recent motorcycle shoot. Here are a few shots that I captured and my views on Canon’s EOS R and Canon EOS RP! Hopefully, this will help you to choose which camera is best for you!

Electronic View Finder (EVF)

You must be wondering why I chose to talk about the EVF first? One of the main reasons I prefer using a mirrorless camera is because I’m able to view what I am shooting through the EVF. Especially in bright daylight, you won’t be to see your exposed image without an EVF and often have to guess how it will turn out through the histogram. However now, with an EVF, you are able to see what you shot even when the sun is shining straight towards your LCD panel. The EVF of the Canon EOS R is of a higher resolution and size (0.5 inches) compared to the Canon EOS RP‘s EVF which is 0.39 inches.

Shutter Speed Limit

This is usually very crucial for day shoots, especially when you really want to use a wide aperture to shoot your subject. The Canon EOS R‘s limit for shutter speed is up to 1/8000 but the Canon EOS RP has a limit of up to 1/4000. Even though you might not need a high shutter speed most of the time due to Singapore’s tropical weather, it will come in handy if the sky goes cloudless in mid-noon.

Size and Weight

To me, this is also one of the key attributes to consider when it comes to getting a camera for travel. The Canon EOS RP is smaller and lighter (132.5 mm x 85 m x 70 mm) compared to its big brother, the Canon EOS R  (135.8 mm x 98.3 mm x 84.4 mm).

Battery Life and Size

TThe key thing about the Canon EOS R is that it uses the LP-E6 series battery, which is the same battery used for the Canon 5D Mark 2, Mark 3, and even Mark 4. On the other hand, the Canon EOS RP uses the LP-E17 battery which is also used for the EOS 760D, 750D and EOS M3.

Despite the Canon EOS RP’s smaller battery size, the battery has a decent life and I was able to shoot for 8 hours outdoors without draining it. However, it does drastically drop in power faster than the Canon EOS R when using the WIFI to remotely control the camera.

The Canon EOS R’s battery usually lasts for 350 frames of shots, which is slightly longer than the Canon EOS RP’s battery which lasts up to 250 frames. These numbers are estimated and when the camera isn’t in WIFI mode.

Wireless Communication

WIFI is included in these two cameras and both worked flawlessly when I was on long exposure in bulb mode. I could just keep my finger on the shutter button in the app to keep the camera exposed until I’m done with my light painting. I was able to see the final shot on my phone instead of going back all the way to the camera to check. Not much difference there.

Ease of Use

In my opinion, the Canon EOS RP was easier to transition between modes compared to the Canon EOS R.Turning the dial was more straightforward to me. I found the multi-slider in the Canon EOS R rather complex. I find that the multi-slider in the Canon EOS R is rather complex. I accidentally changed one of my settings (e.g. White balance) just when my nose accidentally swiped it. That being said, it came in handy when I programmed it to browse through my images instead. Both cameras have an m-fn (Multi-function button) which I loved using to set my ISO. Unfortunately, it supports all other features except for that.

With the swivel screens that come with both cameras, taking photos in different angles was a breeze! The best part is that both of them have touch screens which have made shifting your focus points while shooting so convenient.

RF Lens

Canon recently launched their RF lenses and added a customisable ring on it. With the customisable ring, I was able to adjust the ISO with ease. This is key for most wedding photographers who have to shift ISO quite often especially when switching between indoor and outdoor shoots.


The Canon EOS R has 30.3 effective megapixels while the Canon EOS RP  has 26.2 effective megapixels. Based on the photos that I edited, I noticed that Canon EOS R has a slight edge in dynamic range compared to the Canon EOS RP. Other than that, both make great quality images. The slight difference in megapixel size makes it hard to see a big difference.

Continuous Shooting FPS

I didn’t try this feature as I was mainly shooting stills of motorcycles. However, with awesome tracking in both the cameras, there is a  higher chance in panning shots to achieve a sharper looking photo. The Canon EOS R has 8 fps in one shot mode and unfortunately, it dropped to 5 fps in Servo AI mode, which is mostly used in tracking photography. The Canon EOS RP, on the other hand, has 5 fps in one shot mode and 4 fps in servo ai mode.


Ensuring that our subject contrasts in colour to ensure it can be a point of focus is now a thing of the past with Canon’s latest cameras! Now, these cameras come with Dual Pixel CMOS AF, which can focus faster and more accurately compared to the old AF technology. And the best part is that you won’t miss the focus even in a very low-light situation!

RF to EF and EF-S Lens Adaptor

You are now able to use your EF-S lenses on these full-frame mirrorless cameras! This is awesome especially when you own a few EF-S lenses in your arsenal. These adaptors come in 2 types – one with a ring, and one without. The one with a ring can be customised according to your settings, which in my case will be ISO settings.

ISO Comparison between 2 cameras

Here is the ISO comparison with 100% crop for you to check out. Both cameras are 12 megapixels!

That sums up my review of Canon’s latest cameras. Which one do you think is best for you?
