The first thing I noticed was that my memory card fills up A LOT faster with 18 megapixel RAW files. I only got about 150 shots where with the 8 megapixel XT I was getting closer to 250 in a single memory card. I actually filled the memory card, dumped the files, and went back out to shoot more a total of 3 times to take advantage of what seemed to be the one clear night in December.
