Hey all. Just a quick question. I use to have the Canon Hv30 and there was a way to lock the exposure involving pointing the camera at a bright, white background and pressing a button. This would then keep a nice 1.6 no matter where you shot, completely eliminating any gain (as well significantly darkening the image). This made it possible to shoot candles in a dark room with brilliant results. My question is: Is there any similar way to do this on the Xha1s? I've tried the exposure lock button, but it won't lock. It just goes right back up to 2.8 and so on when I shoot dark areas. Thanks a ton for any help guys!
