Unless you're really pushing the envelope in terms of shutter speeds I don't think IS would be determining factor for choosing a Pen vs. the E-M5. Yes, the E-M5 is somewhat better, but if your shutter speeds are low enough for the difference to matter, they're also low enough that you'll miss shots with either system. IBIS is an aid, not a guarantee.

Only exception would be the E-PM1 and E-PL3 which seem to have a rather weak (or perhaps buggy) IBIS system.

In Ming Thein's E-PL5 review, he mentions that the PEN IBIS is improved over the last generation. I am not sure what he has been able to compare himself, though... think he has an E-PM1 before. I remember hearing that E-PM1 had slightly less effective IBIS than the E-P3, but not sure if this also applied to the E-PL3 (and if it was just due to less body mass)?

The Olympus E-PL5 PEN Lite review: a mini-OM-D

In my own experience I found the IBIS to work very well in the E-P2 and E-P3 (and never saw any issues in my wife's E-PL3 shots).

My expectations are coming from a Canon 1dMarkII with several IS L telephoto lenses then to a G1 and E-PL1. AF is another story but the IBIS of the OMD E-M5 does very well and significantly better than the IOS in the G1 kit as well as the IBIS of the E-PL1. I like the fact that all my lenses are stabilized (adapted as well). One thing to note, not all IBIS is equal across the Pen line.

Here's one I've been trying to figure out...

OMD E-M5 in high speed 9fps has been reported to disable IBIS in between frames. Does the same occur with IBIS turned off with IOS turned on?

I've just been subjectively testing this out with my OMD E-M5 + 100-300 Panasonic. If not shooting at 9fps, I feel the IBIS (IOS off) in the OMD seems like it is more effective. Once I turn on 9fps, I'm starting to feel like I'm better off turning off IBIS and keeping IOS on the lens.

Your lens has an Apple operating system on it?

I don't think so. There's absolutely no communication between the body and lens regarding OIS in the E-M5 and earlier Olympus bodies, so the E-M5 has no way of knowing if the OIS is on or off (which is why, for example, you can accidentally end up with both on). The E-PM2 and E-PL5 apparently change that (the camera does know about OIS now)...

Lol... Brain fart...

My favorite use for the E-M5 IBIS is doing video work. No more jittery camera for me. Rock steady when the subject is in one place, and pans as smooth as butter when the subject moves. Its great for stills too, but it just pays off so much more when filming.

The E-M5 stabilization with a long lens is amazing. This was shot with a 200mm lens at 1/20 sec.

Usayit, there's a setting in EM5 menus to keep IBIS on when shooting in continuous drive mode. I have mine set to keep IBIS on, but I don't recall the name or location of this setting off the top of my head. I'll check my camera next time it's in my hands.

But I think most people accepted that the older Pen IBIS was less effective than Panasonic's OIS with long lenses. I've seen comparisons of the OM-D IBIS with both the 12-35 and the 100-300. The OM-D, in one particular test with the 12-35, was marginally better than in-lens IS. With the 100-300, the OIS was marginally better. Not a big difference in either case, however.

All of the systems will help when you're shooting static subjects hand-held. None of them are a replacement for faster shutter speeds if your subject is moving even a little bit. My experience, starting with a Canon 70-200 IS lens, up to the present day OM-D and OIS lenses, is that IS is much more important with longer lenses.

While it's certainly nice to be able to stabilize wide angle lenses, I don't consider it critical, but if you shoot longer legacy lenses IBIS is very desirable.

I have both Panasonic and Oly m43 bodies, btw, so this isn't about making excuses or being a ******.

I think it depends a lot on what you like to take pictures of. If you shoot a lot of landscapes or cityscapes in low light, IBIS is incredibly useful (maybe even "crucial"). yekimrd's photo above (which I LOVE, by the way!) is a great example. I find that IBIS really extends the usefulness of my Panny 14mm and 20mm lenses.
