Review – Canon EOS M5
Canon launches an EOS M mirrorless camera with a built-in viewfinder – and it’s about time.
While camera makers like Sony, Olympus, Fujifilm and Panasonic have been forging ahead with their high-profile mirrorless camera ranges, Canon has been quietly pottering away on a different path. Its M-series models to date have been pretty conservative box-shaped shooters with a modest M-mount lens range – although they can take regular EOS lenses via an adaptor. The EOS M5 is different. It’s shaped more like a miniature SLR and has a built-in electronic viewfinder. This may not be a big selling point if you’ve just moved up from a smartphone, but for anyone weighing up the pros and cons of a SLR versus a mirrorless camera, the lack of a viewfinder is likely to be a deal-breaker.
The EOS M5 is Canon’s flagship mirrorless camera, replacing the EOS M3 at the top of its line-up – though the EOS M3 continues, as does the entry-level E-M10. Canon says the aim with this camera is to provide enthusiast photographers with the speed, quality and handling of an EOS camera in a much smaller body. The new model presents Canon fans with an interesting dilemma: it’s a fraction of the size of the Canon EOS 80D SLR, but it has the same sensor and many of the same features.
It’s a tiny camera, but it still packs in a 24.2-megapixel APS-C sensor. The resolution is the same as the existing EOS M3, but the M5 has the more advanced Dual CMOS AF system found in the EOS 80D, where each photosite is split into ‘left’ and ‘right’ parts to offer on-chip phase-detection autofocus. This AF system works across 80% of the width and height of the frame. This sensor is matched up with a Digic 7 image processor, which offers in-camera diffraction correction for sharper images at super-small apertures and improved noise reduction.
The EOS M5 can tackle action too, at an impressive nine frames per second if the focus is locked on the first frame, or 7fps with autofocus. The specs don’t include the buffer capacity, but Canon has posted a video introduction quoting a buffer capacity of 20+ raw images. The M5 doesn’t shoot 4K video, but it can shoot full HD at up to 60fps for smooth 2x slow-motion effects. It also has five-axis digital stabilisation; that’s not the same as proper optical image stabilisation, but it should improve handheld footage whether or not the lens being used has built-in image stabilisation.
EOS M cameras use a different lens mount to the regular EOS range. There are just seven EOS M lenses at the time of writing. Designed principally for beginners and enthusiasts rather than pros, they collectively cover a range of focal lengths from 11-200mm, and they all come with Canon’s STM stepper motor autofocus technology, for smooth operation while filming video.
The EOS M5 has Wi-Fi and NFC built in, but it also has always-on Bluetooth LE technology. The camera maintains a constant low-energy Bluetooth connection with your smartphone or tablet, so when you launch the Camera Connect app on your mobile device, it automatically launches a Wi-Fi connection.
Build and handling
For such a small camera, the EOS M5 handles remarkably well. There’s not a lot of room on the top plate, but Canon has still found room for a good-sized mode dial on the left, two control dials on the right and a separate EV compensation dial.
One of the control dials is for customisable camera functions. You press the central button repeatedly to choose the function, then turn the dial to change the setting. It works really well, but initially only two functions are assigned to it, and you have to dig pretty deep in the custom settings menu to find out how to add more. If you don’t know where to find a particular shooting setting, chances are it’s on the camera’s Q Set screen, which displays a row of settings icons down the left and right of the screen.
The memory card and battery sit next to one another under a door on the base of the camera – a bit of a nuisance when you’re changing cards, but a common compromise in small camera bodies. The lens retraction button on the 14-45mm kit lens is fairly flush with the lens barrel and a little fiddly to operate. This lens has a plastic rear-mounting plate: this isn’t unusual on low-cost kit lenses, but it’s disappointing to find the more expensive 18-150mm kit lens option also has a plastic mount. The fact is that both these lenses feel a little cheap. They’re not especially fast, either, since both have a maximum aperture at full zoom of just f/6.3.
The M5’s touchscreen focus works well, but if you use the viewfinder and the touch-focus feature on the main screen at the same time, it’s all too easy to touch the screen accidentally with your nose and focus on something you didn’t mean to.
While Canon’s Dual Pixel autofocus is better than regular contrast autofocus, it seemed to hunt and fail sometimes in poor light situations, where we’d expect an EOS SLR to focus without any trouble. In good light the autofocus works fine. With the 15-45mm STM kit lens, it felt almost but not quite as snappy as a mid-range EOS SLR – and that’s not bad in a camera squashed down to almost half the size. The image results are very good, although the response of the Evaluative exposure metering system proved hard to predict. Very bright subjects led it to under-expose now and again, so we had to dial in some positive exposure compensation to restore brightness to the scene.
The dynamic range proved good but not exceptional in both our lab and real-world tests. Bright, overcast skies could be an issue, for example, as the camera tends to cut off the brightest areas fairly abruptly. At ISO 1,600, the EOS M5’s images look crisp, colourful and relatively noise-free at this setting. They’re a little noisier and softer at ISO 3,200, and more so at ISO 6,400 – which is probably about as far as you’d want to go. The results at ISO 12,800 are still OK, but at the maximum setting of 25,600, the combined effect of noise, smoothing and general softness is pretty excessive.
The EOS M5 yields very similar colour error results to its rivals, the Panasonic GX8 and Sony A6300. The Olympus Pen-F’s results are a little more saturated.
The EOS M5 may have an APS-C sensor, but it fares no better than the smaller-format GX8 and Pen-F in this test. The results are good right up to ISO 6,400, however.
Dynamic range was not really the EOS M5’s strong point in our tests. It’s still perfectly adequate for everyday use, but its rivals edge ahead in this respect.
Meet the rivals…
Olympus Pen-F (RM4,999 body only) The MFT sensor is smaller than the EOS M5’s, but the Pen-F is a retro beauty that delivers great handling and super-sharp images.
Panasonic GX8 (RM4,090 body only) The 20MP GX8 is Panasonic’s current flagship rangefinder-style camera. Prices are falling, and this prestige model looks good value now.
Sony Alpha 6300 (RM4,499 body only) The 24MP APS-C sensor delivers excellent images and the autofocus is impressive, though there is an A6500 model just around the corner.
