Fujifilm have never been big with image stabilization. Only some zoom lenses and now the X-H1 has a built-in image stabilization.
BTW, Fuji people, when asked about why they didn’t include it in the XF 16-55 f/2.8 lens, have said that stabilization degrade the optical quality.
There are two optical image stabilization options with the zooms:
- Mode 1: Continuous image stabilization on
- Mode 2: Shooting only image stabilization which is enabled only when the shutter button is pressed halfway or the shutter is fully pressed.
Mode 1: Continuous Image Stabilization
This means that the image stabilization is always on. If the camera is on then the image stabilization is on.
Benefit: The image stabilization works while using the viewfinder or the LCD at the back.
Drawback: The image stabilization consumes electricity further reducing the life of the battery charge.
Mode 2: Shooting only Image Stabilization
This means that the image stabilization is on only when you either half-press the shutter to focus or when you fully press the shutter.
Benefit: The image stabilization only consumes electricity when it’s time to take the photo.
Drawback 1: The image stabilization may not work, if you do not give it enough time to actually stabilize the image.
Drawback 2: The image stabilization does not work while you are using the EVF or the LCD at the back.
It takes between ½ and a full second for the image stabilization becoming effective. The gyroscopes have to analyse the motion and counter balance it.
