They look cool and easy to carry, but is the new generation of portable video cameras better than their bulky, overweight predecessors? It depends on the make and model, of course. But consider the ergonomic implications of a small video cam and make sure you handle it before purchasing. Trying out the controls yourself is the best way to determine fit and comfort. If you are buying online, a trip down the showroom will be worth the effort, whether or not the return policy is sound. It saves you the disappointment of finding the placement of the buttons awkward for your fingers, or the grip inconvenient for your palm.
