I don't own the OMD, but from everything I've read the OMD has:

1. Less noise at higher ISOs... meaning cleaner, more detailed low-light shots (at ISO 1600 and above).

2. Better dynamic range -- easier to pull details from shadows and to avoid blown highlights in contrasty situations, like at the beach in full sun.

3. Image stabilization with all lenses, making it possible to get sharp shots at slower shutter speeds while hand-holding the camera.

But this does NOT necessarily mean:

1. Your pictures will be better from an OMD than a G5. (You are the one making the picture, not the camera. No camera is a guarantee of good pictures.)

2. Olympus image stabilization is preferable if you already own (or plan to purchase) Panny stabilized lenses.

3. JPEGS from the OMD are better. (This is a matter of personal preference; colors with the G5 are quite good.)

Finally, chromatic aberration is corrected in camera for Panny lenses on the G5, while you have to do this in post-processing for the OMD. You will always have your flash available for fill on the G5 (because it's built in, unlike on the OMD). And video is probably better from the G5 than the OMD. (At least the video specs are better.)

Whether video is better on the G5 than the E-M5 is debatable. Depends on what you look at. A summary of the pros and cons (as far as I am aware) can be found here:

Many comment that the G5 has better ergonomics (handles better) than the OMD. Some disagree. And others point out that if you buy the optional OMD grip, then it handles as well as the G5. (Of course the nice grip is standard on the G5.)

Although the G5 does a nice job with low light photography, if you plan to do a lot of VERY low light work without flash, then the OMD is the better camera. It will stabilize the images from low light prime lenses (such as the Panny 20 and 25 and the Oly 45, 60, and 75), giving you sharper pictures at very slow shutter speeds.

That's my synopsis of what I've read.

A couple of things I didn't see there:

Unlike the OMD, the G5's recording time is not limited to 30 minute clips; you can film continuously for an hour or more with the G5.

Do you have a source for this claim of yours? I am not arguing that you are wrong, I just want to know on what basis you are talking.

Well, the manual specifies that there is a 30 minute limit for clips taken in AVCHD PSH mode and in all MP4 modes. Since it links the limit to only these modes as a footnote to a table that presents other AVCHD modes as well, one can logically conclude that AVCHD FSH, FPH, and SH modes are not similarly limited (in the USA). This would be easy for me to test (with my G5), but the manual seems to precisely restrict the time limit to certain modes and not others. Download the advanced manual and  turn to page 28.

The OMD doesn't shoot at 1920x1080 non-interlaced, like the G5 does.

Yes, that was not covered by the summary post I linked to but was mentioned in a prior post in the same thread and accounts for one of the two points I count in favor of the G5 in the 5 versus 2 point summary I came up with.

The G5 has a fully articulating screen, which is more useful for video than the OMD's tilt screen.

I can see pros and cons with both solutions for stills and video alike. What makes the fully articulating screen preferable specifically for video in your opinion?

You can see it from ANY close location when the camera is filming on a tripod. If the spacial constraints of the room mean that I have to sit 3 feet directly to the left of the camera, or 3 feet directly to the right, or even in front and to the side of the camera, I can see the screen without getting up.  I don't think the EM5's tilt screen provides this kind of flexibility. I have filmed numerous events where such constraints exist. ... like in a church, where you might have the camera on a tripod in the center aisle while you must remain in the pew to the side. In fact, any presentation where you want to monitor the camera from a distance, but your choice of seating is limited.

The OMD does, however, have better manual controls and other video advantages, as your link points out. My comment was focused upon the video specs (full HD, 60p, non-interlaced), where the G5 has an advantage. And since Panasonic has a longer track record in video technology, I tend to trust them more -- I can film an hour and a half presentation or a wedding with the G5, but wouldn't atempt it with the OMD. This is partially subjective, to be sure.

I tried to be even-handed, and noted that the OMD's manual controls outpaced the G5.  To me, that is huge.  I used to own a GH2 and really appreciated the manual control.  The G5 is much more limited in that respect.  But those controls aren't needed for many events.
