Aperture Preview
While you press and hold the key to which you assigned the [Aperture Preview] function, the aperture is stepped down to
the set aperture value and you can check the blurriness prior to shooting.
Hint
Although you can change the aperture value during the preview, the subject may be defocused if you select a brighter aperture.
We recommend that you adjust the focus again.
