Using the X20

So you have pulled the trigger on a new X20? Let’s compile a few tips and tricks to get you started!
Auto-ISO
The X20 has a new Auto-ISO function that is based on the classic X100 and mimics the functionality of the new X100S. In Auto-ISO, you can set the ISO base (minimum ISO / default sensitivity), the ISO limit (maximum ISO sensitivity) and the minimum shutter speed. These settings can also be saved in different customer profiles (C1 and C2).
If you plan to use the DR (dynamic range) function (DR Auto, DR200% or DR400%) you should set the camera to Auto-ISO. Unlike the X10 with its EXR sensor, the X20 needs to raise the ISO sensitivity to a minimum of ISO 200 for DR200% and ISO 400 for DR400%. You can read this X-Pert Corner article to learn more about how to expand dynamic range.
Auto-ISO’s minimum shutter speed can be augmented by the optical image stabilizer (OIS) of the X20 when you set the OIS to one of its two “motion” modes. In these modes, the camera will scan the scene for motion and crank up the shutter speed (and along with it the ISO setting) accordingly. Of course, the camera can only do this when Auto-ISO is active. For example, my X20 chose ISO 400 and 1/320s (instead of ISO 100 and a slower shutter speed) when I shot these horses trotting directly towards the camera:
Once the horses had come to a stop, I took another pic, but this time, the camera reverted back to ISO 100 and a more moderate shutter speed of 1/150s:
Aperture was kept at f/5.0. Both shots were taken in Aperture priority (A) mode.
