Finally, X-H1's IBIS works properly!
The new firmware has changed IS control logics of both IS lenses and camera's IBIS functions.
- For lenses with IS (or OS/VC)
When IS switch on the lens is on, IS function is controlled by camera menu. Mode 1 (Continuous): IS function is always on. Mode 2 (Shooting only): IS function is activated when shutter release button half-pressed and deactivated about 2 seconds after its release. Be noted that if camera body has IBIS, it will be disabled if a lens with built-in IS function is installed.
- For lenses without IS function installed on a camera with IBIS.
Begin with V2.20, IBIS function of X-H1 works properly. It’s controlled by the menu, i.e. Mode 1 (Continuous), Mode 2 (Shooting only) and OFF, which is similar to native XF lenses without built-in IS function.
Be noted, IBIS performance of lenses longer than 100mm may be poor.
In addition to IS function change, following lenses have been added to tested and opimized lens list.
