Everyone’s talking about it – going mirrorless – but you’re still having doubts. Besides, even if you did consider switching, how would you know which model is best suited to you?

You’re not alone – many Canon fans ask this very question. Ranging from APS-C models will smaller lenses to full-frame powerhouses, the entire EOS mirrorless range is designed to bring out the best in your photography; however, we will focus on the full-frame (1x crop factor) cameras in the EOS R series.

Canon EOS R cameras

What is a mirrorless camera?

A mirrorless camera is generally smaller and lighter than a DSLR camera because it does not use a mirror to reflect light into a viewfinder. Instead, it uses an electronic viewfinder that projects the image capture by the lens onto a miniature display used to assist the photographer in composing the shot. DSLRs use optical viewfinders that use mirrors and prism to view the shot before pressing the shutter.

What do EOS R cameras have in common?

This series of mirrorless cameras all have 35mm full-frame sensors that offer better image quality than smaller APS-C or Micro Four Thirds sensors. The EOS R has a slight edge in terms of resolution over the RP yet, thanks to the physically larger sensor, all these cameras benefit users with incredibly detailed images even on low light. This means less noise or grain when selecting higher ISO values.

The advantage of full-frame is that it offers the opportunity to explore new genres of photography, such as landscape and architecture photography that require a wider field of view (FOV), sports thanks to faster autofocus, events due to the better low-light performance, and travel because of its lighter, weather-sealed design yet long-lasting battery life. 

But let’s not forget the beautiful bokeh! Full-frame sensors are able to produce those dreamy, creamy backgrounds that make the subjects of portraits pop. This is because photographers will be able to get their lens’ true field of view on a full-frame and a longer focal length lens will result in a shallower depth of field.

Talking about lenses – making the switch from crop-sensor to full-frame won’t necessarily change your entire setup. Canon EOS R cameras take RF lenses and, using an adaptor, the full range of EF and EF-S lenses without a loss in optical performance.

How do the cameras within the EOS R series differ?

Canon EOS R5 Mirrorless Digital Camera

Because of enhanced, professional features, the Canon EOS R5 comes in at the top of the range and at the highest price point – but it has everything you can dream of and more! A groundbreaking 45MP sensor delivers a combination of high-resolution images, blistering speed (all with AF Tracking) and 8K RAW video performance. This makes it ideal for creatives who wish to switch between photography and videography effortlessly. The camera also features 8-stop in-body image stabilisation (IBIS) with selected lenses for shake-free images and films.

The more affordable EOS R6 also has 8-stop IBIS for shooting ultra-long exposures even without a tripod. Other specifications include 20MP resolution with dynamic range and superb low-light performance down to ISO 102,400. A 12fps mechanical shutter together with Dual Pixel CMOS AF II makes tracking eyes, faces and animals and then photographing them at a fast pace, easy. Finally, it produces 4K Full HD motion picture with realism and clarity.

Released in October 2018, the EOS R was the first Canon full-frame mirrorless camera to hit the market and it did so with incredible specs! Key features include a 30MP Dual Pixel CMOS AF sensor, ISO 100-40000, a silent shutter, -6 EV low light AF, 8fps continuous shooting, 4K and 10-bit movies, a USB 3.1 port, and Wi-Fi and Bluetooth connectivity.

Essentially, the EOS R6 incorporates the latest technology that wasn’t yet available when the R was released:

  • It adds the possibility of shooting HDR photos using the HDR PQ gamma curve for a greater tonal range. 
  • It comes with a new LP-E6NH battery that improves its capacity by 14% (also compatible with the EOS R).
  • It comes with two UHS-II slots, unlike the EOS R which only has one SD card slot.
  • It has a higher refresh rate, but the viewfinders are pretty much the same.
  • It has a vaster ISO range of 100 to 102,400 ISO (plus extended values at 50 low and 204,800 high), while the EOS R has a 100-40,000 range (with pull 50 and push 102,400 ISO).
  • It has the new DIGIC X image processor compared to the older DIGIC 8 version in the EOS R.
  • Thanks to 20fps rolling shutter speed (complete autofocus and exposure tracking), it is more suited to action and wildlife photography.
  • It has 5-axis IBIS with a maximum compensation rating of 8 stops (CIPA) when paired with select lenses, whereas the EOS R does not have IBIS at all.
  • It records 10-bit 4:2:2 internally in H.265 with C-Log or HDR PQ curves. The EOS R does 8-bit internally and 10-bit via HDMI. The crop on the EOS R6’s 4K30 video is 1.07x whereas it is 1.7x on the EOS R.

Still, the EOS R is a great hybrid camera that comes in at a more affordable price point. It has great EVF and autofocus ideal for travel, interior and street photography. If it is processing power and speed that you’re looking for, then consider the EOS R6.

Canon EOS Ra Full-Frame Mirrorless Digital Camera Body

The EOS Ra is optimised for astrophotography so you can capture the full beauty of the night sky. The EOS Ra features an IR filter array in front of the sensor, which enables four times as much Hydrogen Alpha light to be transmitted, compared to the normal EOS R. This enables the camera to capture the distinct reddish colour of a nebula. It also boasts incredible 30x magnification and a more powerful magnification review function for examining images on the camera’s LCD, giving users the ability to zoom in on images at 180% and inspect every detail in captured content.

Canon EOS RP Full-Frame Mirrorless Camera

The EOS RP is a great entry-level option that offers you all the benefits of full-frame yet at a more comfortable price tag. Including batteries, it weighs just under 500g making it incredibly convenient to carry with wherever you go. Spec-wise, it has a 26.2MP CMOS sensor, fast and accurate autofocus, 4K video, and our powerful DIGIC 8 processor for exceptional results, even in low light. Even though it has the RF lens mount, remember that this mount design also lends full compatibility to existing EF and EF-S-mount lenses via an optional EF-EOS R Mount Adaptor.
