Canon PowerShot G3 X vs PowerShot G7 X Mark II Overview and Optics

The Canon PowerShot G7 X Mark II wins the optics comparison with a score of 58/100, while the Canon PowerShot G3 X scores 57/100. Both cameras share several specifications: 20 megapixels, a 1″ CMOS sensor, and a fixed lens mount. However, there are notable differences that contribute to their respective scores.

The G7 X Mark II has a superior shooting speed of 8 compared to the G3 X’s 5.9. Additionally, the G7 X Mark II features a more advanced Digic 7 processor, which contributes to its higher DXOMARK sensor score of 79. The faster shooting speed and better sensor performance make the G7 X Mark II a more desirable choice for capturing high-quality images.

On the other hand, the G3 X offers image stabilization, which the G7 X Mark II lacks. This feature helps reduce the effects of camera shake, allowing users to capture sharper images in certain shooting conditions. Despite its lower overall score, the G3 X’s image stabilization gives it an advantage in specific situations.

In the end, the G7 X Mark II outperforms the G3 X in terms of shooting speed and sensor quality, making it the winner in this comparison. However, the G3 X’s image stabilization may appeal to users who prioritize steadiness in their photography. Each camera has its strengths, so the choice ultimately depends on individual preferences and shooting requirements.
