Canon PowerShot G1 X Mark III vs PowerShot G3 X Overview and Optics

The Canon PowerShot G1 X Mark III wins in the optics comparison with a score of 63/100, as opposed to the Canon PowerShot G3 X’s score of 57/100. Both cameras share some common specifications, such as having 20 megapixels, a 1″ CMOS sensor, a fixed lens mount, and image stabilization. However, there are differences that make the G1 X Mark III a better choice in terms of optics.

The G1 X Mark III has a higher shooting speed of 12, which is more than double the G3 X’s shooting speed of 5.9. This means the G1 X Mark III can capture images more quickly, making it suitable for fast-paced photography. Additionally, the G1 X Mark III has a superior Venus Engine processor and a higher DXOMARK sensor score of 71, compared to the G3 X’s DIGIC 6 processor and sensor score of 63. These factors contribute to the G1 X Mark III’s better overall image quality.

On the other hand, the G3 X does not have any specific advantages in terms of optics over the G1 X Mark III. Both cameras share the same megapixel count, sensor size, and image stabilization features. The G3 X’s lower score is a result of its slower shooting speed and lesser processor and sensor performance.

In the end, the Canon PowerShot G1 X Mark III proves to be the better camera in terms of optics due to its faster shooting speed, superior processor, and higher sensor score. The G3 X, while still a good camera, falls short in these areas, making it a less optimal choice for those seeking the best possible optics performance.

Aspect Ratio
The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.

Canon PowerShot G1 X Mark III vs PowerShot G3 X Video Performance

The Canon PowerShot G1 X Mark III outperforms the Canon PowerShot G3 X in video capabilities, scoring 83 out of 100 compared to the G3 X’s 70. Both cameras share some common specifications, such as a maximum video frame rate of 60fps and built-in time-lapse functionality.

The G1 X Mark III is superior due to its 4K video resolution and maximum video dimensions of 4096 x 2160. This allows for higher quality, more detailed video capture compared to the G3 X, which only offers Full HD video resolution with maximum dimensions of 1920 x 1080. The higher resolution and dimensions of the G1 X Mark III provide a significant advantage for users who require superior video quality.

On the other hand, the G3 X has the same maximum video frame rate and built-in time-lapse functionality as the G1 X Mark III, which means it is still capable of producing smooth, high-quality footage with creative time-lapse effects. However, its lower video resolution and dimensions make it less suitable for users who prioritize video quality.

In comparing the video capabilities of the Canon PowerShot G1 X Mark III and the Canon PowerShot G3 X, it is clear that the G1 X Mark III is the superior option due to its 4K video resolution and larger video dimensions. While the G3 X shares some features with the G1 X Mark III, its lower video resolution makes it less competitive for those who require the highest quality video capture.
