I still haven't found a definitive answer. I've tried searching different forums, dpreview and also reading comments on YT and Vimeo as well, with conflicting answers. I am a video shooter, as well as still images. But, I am mainly interested in this camera for using it's magical, miraculous and revolutionary IBIS during video-mode (as no other hdslr has this), where it is very much welcome....but, with some nice, vintage, MF lenses. However, I did read, here and there, that it may not work on video mode with non-native lenses (like old vintage, MF Canon, Nikkor, old OM, Leica, etc. lenses). But these threads are about 2-3 weeks old and not brought up anymore; so I think the following may have solved this issue..? . After a little more research, and reading 1 dpreview thread, and a few video comments, I read you just need to go into the menu and manually input the correct focal length setting, so that IBIS still works with non-native MF lenses (this is also stated in the pdf manual). Is this all that's needed (inputting the fov in the settings?)? Or, does it still not work fully, even after entering the focal length settings? Can anyone confirm? I am sure a big chunk of the OMD population, and people interested in an OMD, primarily use older MF lenses and are also video-heads, that very much want this IBIS to fully work in video mode with their beloved MF lenses.
