If I put my X-S10 on a table (or any other stable surface), focus on subject and set an exposure the will require more than 1 second of exposure (doesn't matter how many, just make sure that the desired exposure will be more than 1 second), set a timer for 2 seconds and take a shot and the IBIS is set to mode 2 (Shooting only), the shot comes out completely blurry, just like if I hand held the camera (which I didn't).
I repeat the EXACT same steps but this time I set IBIS to mode 1 (Continuous) - shot is tack sharp. Why?
I know that IBIS should be disabled if the camera is on a tripod or any other stable surface, my question is why this happens only in mode 2 and not in mode 1 as well?
Ah a flick of the 'Auto' lever has fixed it! Why do they have to make things so obscure! If it said in the manual 'ES not available in Auto mode' that would have made life so much easier! Anyway, thanks for your help @Greybeard!
