I have a 5DM3 and am a bit confused by conflicting things I have read about locking exposure.
While using Spot metering, I meter on something and want to lock it so I press the asterisk to lock the exposure
1. Do i need to press and hold the asterisk to maintain the exposure or will pressing it only once maintain the exposure? I tried and it seemed to sometimes hold it for me after pressing it once, though other times I am no so sure.
2. How many shots can I keep the exposure saved for? Can I set exposure once and shoot 50 photos without having to re-meter?
Thanks.
