What is the Canon PowerShot G1 X Mark III?
The Canon PowerShot G1 X Mark III is a compact camera and the replacement to the PowerShot G1 X Mark II. However, whereas its predecessor has a 1.5 type (18.7 mm x 14.0 mm) sensor, the Mark III has an APS-C format device which measures 22.3 x 14.9mm, the same as in Canon DSLRs like the Canon 80D. Even better news is that Canon has also managed to make the PowerShot G1 X Mark III 16% smaller than the Mark II and included both a viewfinder and a zoom lens.
Canon PowerShot G1 X Mark III Features
Canon has given the G1 X III a 24.2Mp sensor which is thought to be the same or certainly very similar to the one in the Canon 80D. This is coupled with a DIGIC 7 processor which enables a sensitivity (ISO) range of 100 – 25,600.
For the first time in a compact camera, Canon has given the G1 X Mark III Dual Pixel CMOS AF (autofocus). That means that there’s phase detection focusing in Live View and video mode, just as you get with Canon’s recent DSLRs and mirrorless cameras like the EOS M6. In the G1 X Mark III it’s claimed to achieve focus in 0.09 seconds. There’s also a 4-stop Image Stabilisation (IS) system which should help with producing sharp images in low light when shutter speeds fall.
Canon is still convinced that nobody wants or needs 4K video so the maximum video resolution available is Full-HD (1920×1080) at 59.94, 50, 29.97, 25 or 23.98fps (frames per second). There’s also 5-axis Advanced Dynamic IS in video mode.
As in other recent Canon cameras, the G1 X Mark III has Wi-Fi, Dynamic NFC and Bluetooth connectivity built-in for easy pairing and image sharing with a smartphone. It’s even possible to waken the camera and transfer images to a phone when it’s out of reach, perhaps when it’s your bag after a shoot.
Canon PowerShot G1 X Mark III Lens
As it’s a compact camera, the G1 X III has a fixed (ie not interchangeable) lens. Canon has plumped for a 15–45mm f/2.8-5.6 optic which produces the 35 mm equivalent of 24–72 mm. That’s a drop from the 24–120mm equivalent lens of the G1 X II, but it’s a knock-on effect of using a larger sensor while reducing the size of the camera, so we’ll take it – and it’s still a good focal length range for everyday photography.
The reduction in maximum aperture size from f/2.0-3.9 with the G1 X Mark II to f/2.8-5.6, however, is a bit more restricting, especially in low light. But the lens should be nicely matched with the sensor to optimise image quality and the 9-blade aperture should help make attractive bokeh (out of focus areas).
