I know there are Panny profiles built into the metadata. I was under the impression that this is not true for the Oly cameras. Either way, my understanding is that there are not cross manufacturer profiles built into the metadata. IE not for the Panny 20mm with an Oly camera.The lens correction metadata is a built-in part of*the Micro-FourThirds system. The lenses are designed with specific correction components by Panasonic and Olympus.
The Micro-FourThirds lenses carry the lens correction profiles in the lens itself. It's injected into the raw files at capture time by the camera body as a special kind of metadata, which the Adobe Camera Raw plugin and the Lightrooom raw processor component interpret and apply automatically.
The system is not perfect, there are differences between Olympus and Panasonic as to what corrections they supply and handle ...
- Panasonic lenses contain both lateral CA and geometric correction parameters.
- Olympus lenses contain just geometric correction parameters.
- Panasonic bodies read and inject both corrections into raw files.
- Olympus bodies inject only the geometric corrections.
..but this is why you don't see Adobe providing lens correction files for Micro-FourThirds.
There was a rumor going around that Olympus would soon be handling lateral CA corrections as well, but I don't know whether that's happened.
The corrections are standard to all Micro-FourThirds system cameras and lenses, according to the scheme I wrote up above. I researched and experimented with this extensively in the three plus years I worked with the system.I know there are Panny profiles built into the metadata.

Godfrey - Do you know if the same is true for the Panasonic 14/2.5?The Panasonic 20mm lens geometric corrections are fully supported with Olympus bodies. I know this from testing that exact combination.
It's true for all Micro-FourThirds lenses, to the best of my experience.Godfrey - Do you know if the same is true for the Panasonic 14/2.5?
It does: dropbox.com - Lightroom-raw_lens_correction support exampleDoes Aperture respect this metadata, Godfrey?
I could not find one reason to stick with LR over Aperture, but this could be it, if it's true; I am 100% µ4/3rds now.

The situation is as you quoted I said, yes, even for your E-P1. As response:Godfrey,
I do not doubt that this is the case for later Olympus cameras but not for my EP-1, after converting RAW to DNG in LR there are still corrections needed for distortion and CA. With LR4.1 I have a preset for removing distortion and the CA is done automatically.
The Pana 14-42 and 14-42PZ lenses seem to be corrected for CA and distortion on both the EP-1 and the G2.
Using the Oly 17mm on the G2 requires correction for CA and distortion in PP, although I am not sure whether the corrections are as much as when using the EP-1.
