You already have an AE-L button, not needed of course for M mode. And the way you're using the Green button now is not considered AE lock--that's different. AE lock is only used in an auto metering mode, where if you moved the camera one inch to the left or right, your reading would change. In M mode, your exposure is ALWAYS locked.
Your current use of the Green button in M mode merely SETS the shutter speed based on your selected aperture.
There's a submenu for the Green button which allows you to change its ffunction, and like I said, I use it for Raw.
I don't understand all of the options for the Green button, but I'm pretty sure that most of them involve the automatic metering modes. Since I shoot 99% in manual, I never bothered learning it. In addition, I know there are in-body "electronic ways" to use exposure compensation via shutter speed, but I just prefer to use the lens's aperture ring:
I get my base reading using the Av button, and then adjust aperture one way or the other based on what I think needs to be done, and don't hit Av again.
In many, many ways, shooting manual with our old lenses is just as easy as using a modern lens with AE lock. It's like the exact same number of steps to get where you want to go.
Everyone has their preferences on how to shoot, and this way is mine.
As far as manual focusing goes, mine stinks, so no comment!
