Did Canon change the format of the cr2 file? Is this typical when a new body comes out? I took some shot with my friend's new 5DmkIII but my old Lightroom2 (v2.7 ACR v5.7) won't open the cr2 files. LR4 is already on my list of things to buy. Does it support the 5DmkIII?
On the positive side, a shot a few jpgs too and the exif pane in Lightroom correctly shows the camera model and now reports the subject distance. I can't believe how clean the ISO12800 shots look either.
Also, the file names are in the format K97Cxxxx rather than IMG_xxxx. Is this a new naming convention Canon uses now or just a user preference. My friend really hadn't explored the camera much yet.
