Exposure lock failure
I have a M9 which is three years old. I usually use aperture priority most of the time. When I used the camera today I couldn't get the exposure to lock with a half press of the shutter, i have never had a problem previously but now no m,after how far the shutter button is pressed the exposure doesn't lock and the exposure lock light in the viewfinder does not activate. I have the advance mode set to normal because I am aware that the exposure will not lock in soft mode. Has anyone else had this issue with their M9?
