    Has anyone tried this combination? Wonder about the autofocus speed, quality, and how well IBIS allows for hand holding, especially for wildlife and birds?

    It's a great telephoto on the E-M1. The IBIS is wonderful, but I am not aware of any adapters that allow autofocus....it's manual only.

    Has someone made a magic adapter, and if so, how much does that cost?

    oh no! No autofocus! Back to waiting for the 300 F4 Pro.

    Oh how I wish someone would... This is the most frequently used lens on my E-M1. Autofocus would just be heaven. As far as I know, nobody makes an adapter that supports autofocus for EF lenses on an m43 camera. Metabones makes a smart adapter that allows image stabilization, exif, and control of the aperture, but no autofocus. I'd give up all three of those things for autofocus instead.

    Ray, not Oz
    Metabones makes an adapter that controls the aperture on EF lenses, but unfortunately not AF.

    The metabones speedbooster also does not support IBIS, only IS through lenses which have it built in.

    Source: I own it, IBIS doesn't work (I have to manually set focal length and rotate the lens on bayonet to disengage it if I want IBIS - it's only really useful for subjects which require you to freeze action, if you can get away with the longer shutter time then IBIS wins hands down).

    Wow, if that works, I may not have to wait for the 300mm f4. US $285 sounds pretty reasonable.

    It will be very interesting to see the final weight specs and price for the Olympus 300/4. The 300/4 + 1.4x would give you 420/5.6.

    The EF 400/5.6 is 1250g. You have to add the extra weight of the adapter, but also the Oly TC, so thats probably a wash. I don't think the Oly would be significantly heavier, if its heavier at all than this combo. Plus it will likely focus a lot faster, though to be fair we don't know much about the AF functionality with this Kippon adapter. However, we do know that Canon lenses focus really slow in live view with Canon bodies that only have CDAF, all but a few simply aren't optimized for CDAF.

    The Canon + adapter combo would probably be cheaper though, and is of course available today.

    The Kipon adaptor would need to support the PDAF on the E-M1 otherwise AF would be way too slow. Hopefully we'll hear some reports next month when it starts shipping.
