The audio recorded on my E-PL1 is really bad. Not only is the sound thin and tingy compared to my old Nikon D90, but there is a constant hiss punctuated by a crackle every few seconds. Could I have a defective unit? At first I thought it might be the IBIS, so I turned that off and put the camera on a tripod. The sound did not go away. I tried the SEMA-1 external mic kit. It's even worse, with the external mic mounted on the hotshoe, because it magnifies every sound the camera makes. Even manual focusing the kit lens get picked up and magnified. Moving the mic off-camera is a little better, but for that much work I might as well get an external recorder. Any thoughts or experience with this?
