Canon Announces Powershot G1 X Mark III, Their First APS-C Point & Shoot

By Holly Roa on October 15th 2017

When you think of a Powershot camera, you probably think of a pocket-sized point-and-shoot with a small sensor, the likes of which are rapidly being phased out in favor of the camera everybody has with them – the one attached to their smartphone.

In such an age, companies have got to find ways to significantly differentiate what their compact camera offerings can bring to the table versus a smartphone camera, and Canon looks to have done just that with this update of their flagship compact camera. 

The Powershot G1 X Mark III is the first Canon PowerShot camera to offer an APS-C sensor, something that will add significantly to low-light capabilities and improve bokeh for those who love a shallow depth of field. The 24.3-megapixel sensor is paired with a variable aperture 24-72mm f/2.8-5.6 full-frame equivalent zoom lens.


  • •24.3 megapixel APS-C CMOS sensor
  • •24-72mm f/2.8-5.6 full-frame equivalent, non-interchangeable 3x zoom lens
  • •ISO 100-25,699
  • •Dual Pixel CMOS AF
  • •2.36 million dot OLED EVF
  • •Touch & Drag AF
  • •3.0-inch Vari-angle Touch LCD monitor
  • •7 fps or up to 9 fps with AF fixed
  • •WiFi/NFC/Bluetooth connectivity
  • •Panoramic Shot Mode
  • •Full HD 1080/60p video with 5-axis movie IS
  • •Time-lapse movie mode
  • •Dust- and Water-Resistant construction

There is a definite spec bump over the Powershot G1 X Mark III’s predecessor, the G1 X Mark II, but it comes with an accompanying price bump. The G1 X Mark II’s list price is $799, but the G1 X Mark III will retail for $1299. It is scheduled to become available in November of 2017. 

It’s an intriguing move by Canon. The G1 X Mark III is specced (and priced) similarly to an EOS M5 sans lens options and is housed in a body reminiscent of the G5 X. As technology has trickled down, it will be interesting to see how the public responds to a compact camera that behaves much like their APS-C interchangeable lens mirrorless products.

What do you make of it? Is it forward-thinking enough to be relevant to the smartphone-loving public? Will the inability to change or upgrade lenses hold it back when priced so close to the flagship mirrorless M5?

    So it’s an EOS M5 with a slightly quicker 15-45 kit lens attached.   Hmm. Looks tiny in a good way.

    2.36 million dogs? I love dogs!!!

    In other news, I wonder if this is why Nikon killed the DL line. Maybe they too are going straight for DX P&S…

    That f/5.6 aperture on the long end is a bit of a bummer, compared to something like a Sony RX 100 series.

      it should have similar performance with that aperture at higher ISO since the rx100 has such as small chip tho’

      For DOF equivalence, Matt is right:

      RX100 V at long end is equivalent to 69mm @ f/7.1 on FF
      This G1M3 at long end is equivalent to 73mm @ f/9 on FF
      And for pure light gathering for exposure — where sensor size and equivalence goes out the window — the RX100 is a full two stops better than the Canon (f/2.8 vs. f/5.6).

      But the G1M3 should comfortably outperform the smaller sensor at higher ISO.

      For good light shooting, say for someone looking for a take everywhere during the day type of camera, I think the RX 100 V would be the better choice. It’s not much bigger than a business card. I didn’t hold one until about 2 weeks ago and it’s TINY! 

      A business card is 3.5 x 2 whereas the RX 100 V is 4 x 2.3 – obviously, the thickness is different. The G1X2 is 4.5″ x 3″ which is still small for an APSC camera, but it’s quite a bit heavier and bulkier than the RX 100 V.
