Unable to open Canon raw CR2 file from G1 X (Photoshop cannot open this file), CR2 file from 1DSIII opens ok.
Windows 7 X64, Nvidia 2000D, Photoshop CS6 X64 BETA.
That is correct. the G1 X will be supported in a 7.0 dot release. The camera is currently supported in Lightroom 4.
Note: These cameras are supported in Adobe Photoshop Lightroom 4.0, but not in Camera Raw 7.0. These cameras will be supported in the next dot release of Camera Raw 7.
