The announcement has landed and it’s now official: Canon has released an APS-C RF-mount camera. In fact, it hasn’t just released one – but two – in the form of the R7 and R10. Although it might sound strange considering that Nikon and Sony have been using APS-C models for a while, this is a huge deal since Canon has both the EF M mount and EOS C mirrorless range. This begs the question, is Canon about to scrap the EOS M line?
Panasonic and Olympus ushered in the new age of mirrorless cameras with the formation of the Micro Four Thirds consortium and the release of the Panasonic G1. It was a bold move that oddly had its origins in Olympus’s failure to transition the original film OM to digital. This failure led it to rethink what a modern digital camera should be, releasing the Four Thirds E-1 in 2003.
The camera was a pro model targeted at journalists and sports shooters but, for a range of reasons, never took off. Fast-forward to 2008, and Micro Four Thirds is the same system but without the mirror box. The electronic viewfinder replaced the optical one and allowed for the elimination of pentaprism and mirror box.
While this may seem logical to us with the benefit of hindsight, it was technology-leading at the time and the impact cannot be overstated, because every single manufacturer released a new mirrorless system (and Pentax released two!) each with their own spin on what mirrorless should be.
The Canon EOS M Line and EF-M Mount
Canon was hardly quick at joining the mirrorless party, following Sony (2010), Nikon (2011), and Fuji (2012) with the release of the EOS M in 2012. Like Sony and Fuji, it kitted its camera out with an APS-C sensor (1. 5 crop factor) in order to get a pleasing combination of image quality and camera size. This is in contrast to Nikon which used a CX sensor (2. 7 crop factor) which might have seemed like a good idea at the time but placed limitations on image quality and depth-of-field.
That said, what both Nikon and Canon had in common was their approach to mirrorless: these were seen as consumer products and there was never any intention that a mirrorless camera would be targeted at working professionals. The thinking behind this strategic decision was two-fold. The technological foundations for mirrorless cameras are sound but the implementation is flawed. They were not yet ready to be used in the mainstream because of their poor contrast-based autofocus system and short battery life.
Secondly, DSLRs were making good money! They peaked in shipment value in 2012 and became the biggest camera segment in 2013. You don’t want to introduce a system that cannibalizes your DSLR sales and performs less well.
Then it all changed when Sony introduced the full-frame a7 in 2013; suddenly those cumbersome DSLRs seemed like yesterday’s tech and — while not flawless — the future was clear to see.
This all brings us back to the EOS M line and the two principal problems in transitioning to a full-frame mirrorless system. Firstly, the mount has similar specifications to the Sony E-mount and was designed for an APS-C sensor. Although you can fit a full frame sensor in the mount — which Sony did — there are technical limitations to it compared with mounts specifically made for full-frame. The Nikon Z-mount and Canon RF-mount have these capabilities.
If Canon was going to produce a full-frame mirrorless camera system to replace its DSLRs, then it wouldn’t be following the route Sony took, but starting from scratch to produce something both best-in-class and designed to be long-lived. Secondly, the existing lineup of lenses for EF-M was vanishingly small and still stands at only eight. It made more sense to start over with a brand new mount.
Enter the RF-Mount
It’s arguable as to when Canon decided to develop the RF-mount, but probably around 2015 after having seen the success of the a7. Nikon and Canon faced a dilemma: they both had APS-C and full-frame DSLRs, alongside separate, consumer-oriented, mirrorless systems. How should the professional mirrorless system take shape?
Sony had already taken the plunge with APS-C and full-frame models, with lens systems designed for each sensor size that were fully interchangeable. This flexible system was popular with consumers. Nikon is following suit, implementing a “ground zero” solution. It has already scrapped its mirrorless 1 System and has made it clear it is all but abandoning its DSLR offerings. It’s the Z-system all the way, which has ASP-C and full-frame offerings, again all fully interchangeable. In fact, the company made its intent clear early on, releasing its first Z-system cameras in 2018 (the Z6 and Z7), following them up in 2019 with the APS-C Z50.
Meanwhile, Canon steadfastly stuck to a full-frame only mantra and it took until 2021 for the APS-C rumors to emerge, with the cameras arriving in 2022. The well-specified R7 has impressed us at PetaPixel, while the R10 is a budget-friendly powerhouse.
Both are able to take full-frame lenses, although it would appear – in addition to the 18-150mm – that APS-C specific models are on their way. While Canon has significantly fleshed out the RF lens range, they don’t necessarily make a whole lot of sense for these new APS-C cameras for price, size/weight, or focal length reasons.
Which APS-C Future?
Given the history of Canon’s participation in mirrorless camera manufacturing, one can only wonder about what Canon plans to do now with its EOS and EOS M cameras. That’s a lot of APS-C cameras and lenses to continue selling and developing. Dealing with the second point first… it would seem likely that there will be no development of either the EOS or EOS M lines. The DSLR EOS line is in a deadlock. While Canon seems happy to produce them for buyers willing, this marks the end of an era. Nikon’s exit from the DSLR market may put an extra spin on this segment as sales could oddly begin to increase for Canon, however that is unlikely to lead to new models.
That leaves the EOS M and Canon’s persistence in keeping the range alive, even if the lineup of four cameras was last refreshed with the M50 Mark II in 2020. Perhaps one of the reasons for this is that they sell well in Japan and regularly top the BCN sales rankings. They both have a good reputation in their home markets and make a lot of money. Are they able to keep developing their products? Two RF-mount cameras have been released and one RF-S lens has also been published.
Canon categorically denied that the EOS and EOS M ranges would be discontinued. This — at face value — appears to make economic sense. For how much longer this continues to be the case remains to be seen, but I would be surprised if we see many cameras in these ranges surviving beyond 2025. This is an opportunity for RF.
