I wounder if the heavy cameras such as Canon 50D would be hard to travel with and take lots of family pics, etc? would weight makes hand shaking when hold for too much? does it need a tripod for it's weight? or should it be skipped and go for something lighter like the 500D if one was searching for portability over performance? excuse me for asking lots of questions similar to each other, I hope you've got my point. thxx
