I'm a big fan of Adobe Systems' camera profiles, which when editing the raw images that higher-end cameras can produce imbues photos with what I find to be more natural hues. So I was glad to hear.
I apply the "camera faithful" profile by default when I import photos from my Canon SLR into Lightroom. But when I tried to use the profiles on some photos I took with an Olympus E-3, I found I couldn't.
Now seemed a good time to find out exactly which models are supported, and Adobe obliged with a list.
All SLRs from Canon and Nikon, which dominate the SLR market, are supported in the profiles that ship with Adobe Camera Raw 5.2, and that's a good start. But things get thinner after that.
The Pentax K10D, K20D, and K200D SLRs also have profiles, as does Leica's expensive and somewhat exotic rangefinder, the M8. Only two compact cameras, Canon's PowerShot G9 and G10, have profiles.
There are no profiles for Sony, Olympus, Samsung, or Panasonic SLRs so far. No doubt Adobe is working on it, though. I'll update this post if I hear further details.
