Our Verdict

Where its predecessor was capable as a compact system camera, the Canon EOS M6 Mark II is a potent primary camera – regardless of category. Its powerhouse 32.5MP sensor sets a new benchmark for APS-C systems, along with ferocious 14fps continuous shooting and uncropped 4K video – all in a truly pocketable body with an optional viewfinder should you so desire. In everything save the mount and sensor size, this is poised to be an EOS R beater.

For

  • Monster 32.5MP APS-C sensor
  • 14fps continuous / 30fps burst
  • Uncropped 4K with Dual Pixel CMOS AF

Against

  • 180° screen, though no articulation
  • No in-body image stabilization
  • Native EF-M lenses still limited

The original Canon EOS M6 was easy to like, but difficult to love – much like the EOS M line as a whole. With Canon’s APS-C mirrorless camera range having seemingly plateaued at 24.2MP, there were only so many bells and whistles that could make the M6 feel exciting – things like 4K video, which were sadly absent.

It left the M6 with that awkward 'second camera' tag; that it was good enough to be your backup, or the one you took out when pictures weren’t quite as important, but it wouldn’t demand your attention beyond that. 

Well, you can officially throw that line of thinking out the window – both for the new Canon EOS M6 Mark II and the EOS M series as a whole. 

With all the tech that comes across our desks, it takes a lot for a camera to impress us these days. The M6 Mark II, however, took us completely by surprise with what it can do, and how capably it can do it. It's one of the best cameras for vlogging right now and certainly one of the best Canon cameras for those who want to go mirrorless. If you want the best camera for filmmaking, however, you may want to set your sights a little higher.

The new powerhouse 32.5MP sensor gives this camera a higher resolution than its big brother, the Canon EOS R. In fact, the M6 Mark II packs more megapixels than any Canon body save the 50MP 5DS/R – not at all bad for the supposedly humble APS-C format.

Indeed, not only does it outmuscle the EOS R in the resolution stakes, it also outperforms it in a number of other departments – not least its freakish 14 frames per second continuous shooting mode, and the fact that it can shoot 4K video without any crop factor.

Putting the two systems side by side, it actually becomes a challenge not to choose the Canon EOS M6 Mark II over its full-frame mirrorless siblings; it’s a more compact camera than the Canon EOS RP, and a more capable camera than the EOS R. 

While the Canon RF lens roadmap is undoubtedly better curated than the EF-M lineup, both mirrorless formats are still largely dependent on their seamless compatibility with traditional EF lenses. And, that being the case, the new M6 feels more compelling than its bigger brothers…

Build and handling

The Canon EOS M6 Mark II is slightly beefier than its predecessor, which measured 112.0 x 68.0 x 44.5 mm and weighed in at 390g, but it remains a micro marvel. Even more so, in fact; for a camera this capable to be packed into a body this small is quite remarkable. 

However, there’s a temptation to conclude that its pocketable profile means it’s only fit for being a “travel camera” or a “street camera”. And yes, it is very much ideal for both of those things – but a more apt conclusion would be that the M6 Mark II is so small that it can transform the way you shoot, because you simply don’t require the bulky bodied system that you always thought you did.

By once again omitting a built-in viewfinder, the Mark II retains the sleek form factor that makes it at once compact for travel, discreet for street photography, one-handable for vlogging, and that perfect Goldilocks-size that’s still substantial enough for ‘proper’ shooting.

Far from being a churlish move on Canon’s part, the decision to make the viewfinder an optional extra plays to the M6 Mark II’s strengths. The existing EVF‑DC2 (available in a kit with the camera) can be kept in a pocket and mounted to the hotshoe as and when required – this keeps the camera pocketable and portable, in a way that the EVF pentaprism would prevent. 

One of the nifiest additions to the Canon EOS M6 Mark II’s exterior is the new MF / AF toggle switch, filling part of the huge space next to the rear thumb grip. Seemingly superfluous at first, it quickly becomes a valuable part of your muscle memory – particularly with lenses that don’t feature their own an external MF / AF switch. 

The body features an ever so slightly chunkier grip, which helps it retain balance especially when using adapted EF lenses – something that will almost definitely be required, since the EF-M mount isn’t nearly as well catered for as its EF and RF counterparts.  

Its magnesium alloy chassis and thermoplastic exterior feel strong and sturdy, though the M6 isn’t an all-weather body and as such it’s not going to take the knocks that a 5D can.

Performance

We first tried the EOS M6 Mark II in conditions that were far from optimal, in a dimly lit indoor karting track that was somewhat akin to shooting in the basement of a parking lot at night. Even so, the M6 Mark II impressed us. Subsequently we've tried it in more normal outdoor lighting, both for stills and video. 

The poor lighting certainly tested the ISO performance, while also putting the improved -5EV low light focusing through its paces. With the smaller sensor, noise does start to rear its head when you push beyond ISO1250, and capturing moving subjects at high speed meant that we had to exceed this by some margin. 

We cranked the ISO all the way up to 6400 for some low light test shots, such as the Budweiser sign, though the circumstances under which you would have to do likewise should be fairly slim. 

Despite the torrid illumination, the Canon EOS M6 Mark II’s 14 frames per second continuous shooting (with continuous AF) did a stellar job of keeping up with the action, capturing the cars as they came careening around corners. In fact, in some extremely limited testing, the improved Eye AF tracking even came in useful if drivers’ visors were up, as the camera was quick enough to find and follow eyeballs.

Finding focus manually is similarly smooth and simple, either tapping your focus point if shooting on the back screen or using touch-and-drag if using the EVF – a quick and capable replacement for a joystick, though obviously it’s not optimal in environments where cold fingers are less apt to be registered.

While the lack of full articulation is a pity, the fact that the screen flips 180° does make it more vlogging-friendly – though the 180° display is impeded if you have something mounted on the shoe. This, and the lack of a headphone jack, makes the M6 Mark II less suited to pure video shooting than the Canon EOS 90D – an unfortunate oversight, as the smaller form factor would make this the more obvious vlogging body.

That notwithstanding, its 4K video comes up trumps. Not only is the footage uncropped, but the Dual Pixel AF is now fully functional while shooting 4K – and the camera now features clean HDMI output. Crop factors of varying severities can be introduced when using digital image stabilization, which is certainly effective but obviously eats into your composition.

Video

The EOS M6 Mark II does make a great camera for video, though it's more for the vlogging end of the market than serious filmmaking. It's very compact, it's very light and it's the easiest camera we've tried for gimbal mounting. You can see our sample video below.

The face/eye AF is excellent, and worked perfectly for our walking video test. It also has a large AF area (100% vertical x 88% horizontal). The 32.5-megapixel resolution is not directly relevant for video, where the 4K UHD resolution is 3840 x 2160 pixels – a lot less than the full 6,960 x 4,640 pixels for stills – but the M6 Mark II produces decent quality 4K footage regardless, with great color rendition.

The 180-degree flip-screen is useful when you're filming yourself, though it has a tilting mechanism rather than the fully-articulating pivot found on many other Canon cameras.

Overall, it's a fun little camera you can shoot some decent footage with. The buttons and switches are a good size and feel solid, and the menu navigation is easy, as we'd expect from a Canon.

It's not all good. The EOS M6 Mark II does not yet shoot 4K at the popular 24fps frame rate (which we're told is coming) or at 60/50p (which isn't). There's no in-body stabilization, so it's just as well it's light and wieldy on a gimbal, there's no zebra pattern exposure warnings, and no headphone jack to monitor the sound. The lack of a headphone jack is a surprise, since the technically similar EOS 90D DSLR does have one – and it's not often you can say a DSLR is better equipped for video than its mirrorless equivalent.

You can shoot at a high frame rate in 1080p resolution, but not with continuous autofocus, and you don't get any log profiles either – though normally you'd only expect that in more expensive cameras.

Lab data

Resolution

(Image credit: Future)

With 32.5MP on tap, it's small wonder that the EOS M6 Mark II comes out on top of its key rivals at lower ISO sensitivities in our resolution test. However, increased image noise at sensitivities past ISO 3200 results in obscured fine detail and eventually the M6 II falls behind its competitors at ISO 12,800.

Dynamic range

(Image credit: Future)

The EOS M6 II delivers an almost identical amount of dynamic range to the Fujifilm X-T30 throughout the tested sensitivity range – no mean feat, as the X-T30 is very strong in this area. However, the new Canon still has some way to go if it's to match the Nikon Z 50's class-leading dynamic range at higher ISOs.

It's worth noting that any in-camera dynamic range enhancement is disabled for our lab testing in order to get a level playing field.

Signal to noise ratio

(Image credit: Future)

Our signal to noise test measures image clarity, specifically the ratio of the actual image 'data' you want to capture, versus the image noise that you don't want, but will inevitably be visible when shooting at higher ISO sensitivities. The higher the score at a given ISO sensitivity, the better.

Generally, the higher the pixel density on a imaging sensor, the more image noise is generated at a given ISO sensitivity, putting the 32.5MP Canon at a theoretical disadvantage in this test compared to it's slightly lower resolution competitors.

And these results prove the theory translates to reality, as both the X-T30 and Z 50 come out ahead, and by a fairly wide margin at higher sensitivities. The EOS M6 II does stay ahead of the Sony a6400, which we'd expect given Canon's 32.5MP sensor is a newer architecture than the 24.2MP chip in the Sony.

Verdict

The Canon EOS M6 Mark II has given new life to the previously flagging EOS M line. We’d even go one step further and offer that the M6 Mark II might be the best mirrorless camera that Canon has yet released. Yes, it lacks the larger sensor and more robust offering of native lenses, but in almost all other respects it is operationally superior to both the EOS R and RP. More megapixels, higher frame-rate, uncropped 4K video… in many respects, this is the camera that its older brothers should have been.

With a faster continuous mode than the Canon EOS 90D, it’s arguably a more adept action camera for subjects such as wildlife and sports than its new sibling – though the 90D, somewhat bafflingly, possesses the extra tricks (the articulating screen and headphone output) that make it more capable for video. 

The Canon EOS M6 Mark II is a ferocious little performer. A true jack of all trades, but not in a pejorative sense – this camera pumps out high quality pictures and captures crispy 4K video, both of which are worthy of far pricier bodies.
