Canon PowerShot G1 X Mark III review

Canon has somehow shoehorned an APS-C-sized sensor into its flagship compact camera, but it’s come at a cost

Digital Camera World Verdict

Great as it is, the image quality alone isn't enough to make the PowerShot G1 X Mark III stack up. The big sensor has forced a compromise in the lens design that you could accept in a DSLR or mirrorless camera's kit lens on account of you being able to change it – but here, it's not so easy.

Canon's PowerShot G-series cameras are aimed at serious photographers who want some of the power, control and image quality of a DSLR, but in a camera they can slip into a jacket pocket – and with the PowerShot G1 X Mark III, Canon has produced what it calls the "ultimate" G-series camera.

Its key selling point is that, for the first time, Canon has squeezed an APS-C sensor into a PowerShot body. The 24MP Dual Pixel CMOS AF sensor is similar, Canon says, to the sensor in its enthusiast EOS 80D DSLR, which is pretty near the top of its APS-C DSLR line-up.
