    I am trying to find out that if I leave the IBIS setting to automatic when I am using my Olympus 4/3 50-200mm SWD with teleconverters (EC-14 or EC-20) , will the OM-D E-M1 will recognized the setup and automatically adjust for the actual focal length of the combo.

    Also if I use and old Canon 400mm FD for example, do I manually put 400mm or the actual 35mm equivalent of 800mm?

    I'm not sure about the 4/3 lens, but with any adapted lens put in the actual focal length on the lens.

    Yes. Manually setting the focal length has no effect for lenses that communicate with the camera body (e.g. most m4/3 and 4/3 lenses, including when using the EC14 and EC20.

    400. Feels like we need an FAQ for this one...
