Canon EOS M3 – Features

With a solid, but not exactly class-leading specification, Canon seems to have decided that the EOS M3 should keep prospective buyers reasonably satisfied without treading too much on the toes of its DSLR range. That 24.2MP sensor offers a sensitivity range of ISO 100-12,800, expandable to ISO 25,600. Shutter speeds run from 30secs up to 1/4000sec, and continuous shooting operates at 4.2fps with a five-image raw buffer (although unlimited shooting in JPEG). This isn’t too bad, per se, but it’s worth noting that the similarly priced Samsung NX500, that was announced around the same time, trumps the M3 in every specification.

It’s much the same story in video. The M3 is capable of recording full HD 1920 x 1080-pixel movies at 30fps, 25fps or 24 fps, with built-in stereo mics and the added bonus of a 3.5mm jack for an external microphone. A focus-peaking display is available for manual focusing, which is displayed during recording to aid pulling focus from one subject to another. However, there’s no overexposure-warning display.

The M3 has a 3in, 1.04-million-dot rear touchscreen that is hinged to tilt 45° downwards, upwards or fully forwards. However, while other brands automatically turn on useful ‘selfie-assist’ modes with face detection and short self-timer delays, Canon has no truck with any of this new-fangled nonsense, so you have to set the camera up yourself. There’s no built-in viewfinder, but an optional EVF is available (more on this later).

Other features include the now-obligatory built-in Wi-Fi for connection to a smartphone or tablet, allowing remote control and image sharing. An NFC chip in the camera’s base enables easy pairing with compatible devices. One nice touch is that the M3 also has an IR receiver in the handgrip, for a more traditional take on wireless remote control.

    I see vignetting for sure, but not green.

  • Brian

    I have both the EOS M and M3 and the 18-55mm kit lens and I have never had the issue you speak of.

  • Kevin Levrone

    There is a distinct green cast on the corners when you shoot with the 18-55 lens at 18 to 25mm or when you shoot with the 22mm lens, even with all corrections enabled. This kind of ruins the image quality. It even appears on one of the photos in this article.

    Nice camera but they should have included a viewfinder just like the DMC-GM5. The two camera will make a great comparison.

  • entoman

    A very nice camera, and for the majority of potential users the very limited range of lenses will be adequate.

    However if Canon want serious photographers to adopt their mirrorless products, they need to offer something that will compete with Fujfilm XT-1 and Olympus, i.e. pro-level quality and a complete system of lenses.

    Personally I prefer to use Canon’s superb APS and full-frame DSLR system, but there are many who yearn for a compact mirrorless system, and Canon are not showing any signs of addressing this market seriously.
