Product Review Mode

Setting [Product review mode] in the video recording menu to [On] or [On (customize focus area)], the camera will quickly switch the subject in focus when the subject appears closer to the camera. For example, when shooting a video with a person in focus, if a product is brought in front of the camera, the focus will quickly switch from the person's face to the product. This makes it useful when shooting product review videos.

Select [On] to set the focus on the foremost subject in the entire shooting area.
Select [On (customize focus area)] to choose the dimensions (measured in focus points) of the AF areas. Highlight [On (customize focus area)] and press 2, then use 1 and 3 to choose the height and 4 and 2 to choose the width of the AF area.

Product Review Mode

When [On] or [On (customize focus area)] is selected, some items (including focus mode and AF-area mode) are fixed to settings that suit product review shooting and cannot be changed.
