Frosty morning at the BCLM

Panasonic GH2, 14-140mm. It's a bad workman who blames his tools, but the image I would really have liked to use today needed multiple exposure, so must go back again with the D200 tomorrow, if conditions are still suitable! GH2 is my favourite camera, but I wish it had (in no particular order):
1. GPS
2. Multiple exposure
3. Panorama facility like the Sony A55 (but ideally RAW, not sure how it could do this!)
