OK guys. Tomorrow you'll have your raws (thanks for the info about acr!!!!).
70-200 II@135mm f/4, manual live view focus and iso 1600-3200-6400-12800-25600. Any suggestions for better settings?
I 'll upload the raw files to a filehosting site and we 'll discuss the results together

Do not forget that I'm shooting in a well-lit environment though.
