Based on research seems some reviewers say the fuji ibis over corrects sometimes , leading to some weird jerkiness..
So has a hard time sometimes differentiating between intended movement and not intentional.
How ever should be correctable with firmware upgrades.. as its similar to what panasonic and Olympus experienced during there first attempts at ibis
I am waiting for IAIS - In Arm Image Stabilization in which you replace your arms with bionic arms that act as image stabilization/gimbals all in one.
Then and only then will my clients be satisfied with how steady my shots are.
