Stop Blurry Kids Photos with Sony Cameras! How to Set ISO AUTO Min. SS [α7cII / α7IV]

You capture your child running happily in the park or jumping in the air — only to find the photo is blurry when you check it later. Sound familiar?

The most common cause of motion blur is a shutter speed that is too slow.
When left on auto, the camera prioritizes exposure and lets the speed drop too low.

The Fix: Set ISO AUTO Min. SS

This setting lets you tell the camera the minimum shutter speed it can use. If the speed would fall below that limit, the camera automatically raises the ISO to compensate for the exposure.

Where to find it (Sony α series)

MENU › Exposure/Color › Exposure › ISO AUTO Min. SS

Recommended values

Tip: Assigning this setting to the D-pad or a custom button lets you switch it on the fly to match the scene.

Also Worth Setting: ISO Limit

Once you set ISO AUTO Min. SS, the camera may push ISO higher in dark conditions. Too high and noise becomes noticeable, so set a maximum ISO you are comfortable with.

Recommended ISO limit

※ Noise tolerance varies depending on the camera model and intended print size.

Summary

• Set ISO AUTO Min. SS to 1/250–1/500
• Use 1/500 for fast-moving action
• Set the ISO limit to around 12800
• Assign to a custom button for quick access
