Well, I've found a flaw in the M6... er... rather a flaw in myself that pertains to the M6. The meter will come on if the shutter release is pressed slightly down, and won't turn off until however many seconds after you release it. In order to turn this off you rotate the shutter speed dial to B. Well, I'm not so good at remembering this, and so I have killed the 2 batteries I had for the camera. While in my Domke F803 bag, the shutter is pretty much always partially depressed, so after about 8 hours, the battery is no more. I just need to get into the habit, or I will be wasting a lot of cash on batteries. Actually I have no idea how much these batteries cost, but I guess I'll find out tomorrow.
