Canon PowerShot G7 X Mark III vs Ricoh GR IIIx Overview and Optics

The Ricoh GR IIIx outperforms the Canon PowerShot G7 X Mark III in optics with a score of 68/100, an 11-point lead over the Canon’s score of 57/100. Both cameras have CMOS sensors, fixed lens mounts, and image stabilisation. They also share a similar shooting speed, with the Canon at 30 and the Ricoh at 4.

The Ricoh GR IIIx excels with its 24-megapixel resolution, APS-C sensor size, and a DXOMARK score of 76 for its sensor. These features contribute to the Ricoh’s superior image quality and detail capture. The GR Engine 6 processor also ensures fast and efficient image processing.

On the other hand, the Canon PowerShot G7 X Mark III has a 20-megapixel resolution, a smaller 1″ sensor size, and a lower DXOMARK score of 58 for its sensor. While its Digic 8 processor is reliable, it does not match the performance of the Ricoh’s GR Engine 6. However, the Canon boasts a significantly higher shooting speed of 30, which may be appealing to some users for capturing fast-moving subjects.

Despite the Canon’s advantage in shooting speed, the Ricoh GR IIIx’s higher resolution, better sensor size, and superior DXOMARK score make it the winner in terms of optics. The Ricoh offers better image quality and detail capture, making it a more suitable choice for photographers who prioritize these factors. The Canon PowerShot G7 X Mark III may still appeal to users who value shooting speed, but it falls short in overall optical performance compared to the Ricoh GR IIIx.
