It is no problem to use the lens correction in PS CS6 with my EOS 7D and the 24-105 IS L lens. Using my new EOS Mark III with the same lens, Photoshop does not recognize the lens. And in the dropdown menu, where you can normally choose the camera type, Canon is no available (Nikon, Pentax, Sony... are available.). Why is that so? Lightroom 4 has no problem with that issue.
I know fairly little about how Adobe accumulates lens profile data, but I have always thought that it's at least in part user-submitted (though I'll be darned if I've ever run across a description of how to do it).
Perhaps it is as simple as no one having submitted profile information using a full frame camera for that lens.
You can see it for your 7D because someone may have submitted information describing the characteristics of the 24-105 zoom for a 1.6x crop camera. Adobe would not be able to apply that to a full frame camera, because they simply would not have measurements of what the lens is doing to the image out past the edges of the smaller sensor, and so they leave it off the list.
All this is just speculation. I'll be curious to see if I'm near the mark.

Hi Noel,

I don't keep up with this utility so I can't say if it's very active. The last update reads 4/2011.
