    I am in charge of firmware at Metabones and I would like to give an official response with regard to GX80/GX85.

    We do not expect any EF mount to be able to take advantage of Dual I.S. in the foreseeable future. Either OIS or IBIS should be used, but not both. Andrew reported that "They seem to both operate and ignore each other, leading to problems." We could confirm that it is indeed the case when we downgrade to 1.4 or before. This was fixed in 1.5 a long time ago (Feb 2015). It is easy to tell one way or another: if both OIS and IBIS are active simultaneously, vibration will be overcorrected by twice as much and there will be just as much jitter as no IS, which is indeed what we see with adapter firmware 1.4 or earlier. If you are seeing just occasional slow jitter, it is likely you are observing the result of the vibration exceeding OIS' capabilities of that particular lens.

    We have a 50-100/1.8 on order, but before that arrives, the most likely hypothesis drawn from Andrew's and our own observations is that adapter firmware 1.5 and after breaks the 50-100/1.8 and the old firmware 1.4 and before breaks all IS lenses (no AF and double correction). If this hypothesis is correct, you are okay with the current adapter firmware except for the 50-100/1.8 and except for the fact that you will be always using OIS but never IBIS.

    A new adapter firmware will be around the corner with which we expect the 50-100/1.8 to be fixed as well. There will be a new option to choose between IBIS and OIS on Panasonic in the next firmware, something that is just natural for Olympus but not yet possible for Panasonic. (On Olympus if you turn off lens IS, IBIS comes on, but on Panasonic the lens IS switch turns off both OIS and IBIS.) The procedure to turn off OIS and turn on IBIS on Panasonic is not going to be pretty, but it will be doable.

    I enjoy reading Andrew Reid's very informative review and tests, we greatly appreciate his work and we are always listening to customer reports of any issue which might arise. However, we would like to advise our customers that writing to support@metabones.com is the only way to ensure a problem is looked into in a timely manner. I do read eoshd often, but it is not a reasonable expectation that just because something is reported or discussed on eoshd we must be working on it. We appreciate you informing us of any issue via the official support channel in advance. That would greatly expedite the fix.

    I've also sent an email (couple days before your post here) regarding OIS IBIS with 2.3 firmware but never got a response..

     

    Good to hear that it will be fixed for 50-100/1.8 and we'll have an option to select IBIS or OIS on panasonic body...Although DUAL IS would be awesome :-)
