    or off on the body, on on the lens?
    Both systems work together, and turning OFF the switch on the lens turns both systems off.

    Thanks, exactly. IIRC, I think for that lens OSS (Sony's name for IBIS) is greyed out in the menu.

    For OSS lenses pitch and yaw stabilization seems to be provided by the lens whereas roll, X and Y stabilization is provided by the camera. The system needs to know the focal length. For X and Y stabilization it also needs to know distance to subject.

    X and Y stabilization contributions are most important for close focus and go to zero for infinity.

    So, when the lens doesn't communicate electronically focus distance information to the camera body, IBIS does pitch, yaw, and roll stabilization.

    Of course, for native but non-OSS lenses the camera's IBIS does all 5 axis corrections, i.e. 5 inputs for 3 outputs. The sensor doesn't tilt. It can move in X and Y and rotate within the X-Y plane.

    Re: New lens lineup for the A7rII

    Time for me to jump into the pool on this excellent forum...

    Two years ago I sold off my Canon gear to start again with the A7. I ended up returning 2 A7 bodies due to issues I just couldn't live with and privately concluded that the A7 just wasn't quite ready. Since then I've been amusing myself with an RX100 and an RX1R and had a brief, hello-goodbye affair with an E-M1.

    From the day of the announcement the A7R2 looked to be the one I've been waiting for and so far I have not been disappointed. I bought 3 lenses for it - I used my brain for a change and decided to push the impulse buys and the fine tuning off into the future, after I get more time with the kit...

    16-35/4
    55/1.8
    70-200/4

    Am looking forward to adding to this forum and benefitting from the talent and experience of its members...

    Hi JM - welcome! I'm fairly new here and have learned a lot from and been inspired by the forum. That is a great starting lineup and I applaud your thoughtfulness in slowly acquiring gear - I hope to learn to do so myself. Or at least get better at selling, I've got buying down pretty well.
