Canon g1x mark ii iso最低400

The Canon G1 X Mark II has a native ISO range that starts at ISO 100 and goes up to ISO 12,800. However, it also has an expanded ISO range that goes down to ISO 80 and up to ISO 25,600. So, while the camera's standard lowest ISO setting is 100, it can be set to 400 or any other value within its range for different shooting scenarios.

The ISO setting determines the camera's sensitivity to light, with higher ISOs allowing for better performance in low-light conditions but potentially introducing more noise into the image. Lower ISO settings are generally preferred for better image quality in well-lit situations.

To set the ISO on the Canon G1 X Mark II, you can use the dedicated ISO button typically found on the camera body, combined with the main dial or a secondary dial to select the desired ISO value. The exact method may vary slightly depending on the camera's shooting mode and any custom settings you have applied.

Remember that while you can set the ISO to 400 or any other value, the camera will still perform best at its native ISO range, as extended ISO settings may result in more noticeable noise or other image quality issues.
