I'm more of a "Green Button Advocate" than apologist. Even if full K compatibility was added I'd still use the green button as I do now. I can set the aperture I want, zoom in on the subject, tap the button and it sets the proper shutter speed. No fiddling with the dial and watching the little LEDs. I can now shoot to my hearts content, not worrying about things that would normally fool Av. Only if _the light on my subject_ changes do I have to adjust exposure with another quick tap on the button. Works for me. Only in very quiet settings do I find this a PITA, I then go to the more fiddly manual mode with the lens set on A, or Av with a stop down type/modified lens. All depends on the situation. On some of my other bodies I use the exposure lock button in a similar way, on most of them however the EL clears either when the shutter is released or the meter times out, with the green button the setting stays put until _I_ tell it otherwise, I like that.
