With m43 you just open up two stops rather than raising ISO two stops. m43 has a two stop advantage in DoF so that with the same framing, a FF f:5.6 shot can be made at f:2.8 by m43, with equal DoF. (Shutter speed is irrelevant.) IOW, altho m43 users "lose" two stops of ISO speed, youll still get the same shot with the same DoF, at the same shutter speed, relative to FF users.

Theres plenty many Hawgsters will insist that the above equivalency is just myth and fake math. But most of those also have a death grip on their SLRs, so whoever want to belive that bunch deserves to do so. Im not their messiah. Truth is a take it or leave it deal.

This from DigitalCameraWorld.com on the Oly 100-400. DP Review verified this as well. I am assuming they know what they're talking about.

"The Olympus M.Zuiko 100-400mm f/5.0-6.3 IS comes with the weather sealing and freeze-proofing that is normally reserved for Olympus' series of Pro lenses – though it doesn't feature the Sync-IS system featured in Pro glass (which works in tandem with the in-body image stabilization of Olympus cameras, to provide extra stability), instead offering 3-stops of compensation via lens IS. "

In summary, the two image stabilization systems do not work together.

Users report that using IBIS or lens only stabilization works just fine. I have the Pany 100-400 which is in the same boat when paired with my Oly gear...I don't see a problem..works just fine for me.

Thanks, that was my understanding as well. Have you tried to do handheld video at 400mm focal length with this lens?

I have...what I do is brace myself, as if shooting a pistol, against something and it works great. I attached a photo that I think was shot out that far. If not it was nearly at 400. The santa was real! Not. I just added it on PS as a lark since I shot this on Xmas eve.

I also have used it straight up hand held and it works...need to have a decent shutter speed, of course, but it works.

Frankly, I'd look at the Oly 150-600 if I shot long stuff...but I can't justify it. This was the Pany lens...a very good copy I might add.

For me, m43 works just fine.

Thanks, want a lighter lens and don't really think that I would shoot at 600mm. Plus prefer having the 100mm at the low end (ie. 200mm 35mm equivalent). So was hoping for an updated version of the 100-400mm which had image stabilization that worked with the camera or better low light abilities (ie. wider aperture). Not a longer FL. Will wait, maybe their next lens will fit better what I am looking for.

PS. For my video I shoot at slower shutter speeds, 1/50 or so.
