One thing I've heard of people doing before with camera gear is a vest with a lot of pockets for lenses, etc. if the airline you're going to be on is a stickler about the bag weight. One time on ET out of BKK, my carry on was overweight and they were checking everyone gateside. So I took out a bunch of stuff, threw it over my shoulder and said "there, the bag is under 7kg now"... he was satisfied enough, I walked 20 meters ahead and put it all back inside.
