There are important differences in use between M and A exposure modes...
In M, all settings are "locked-in" as you make them, so it is easy to
point the camera as needed for best metering, with no need to then lock
the exposure setting before reframing. Also, if you wish to compensate
the exposure, you do it directly with the aperture and shutter speed
settings, rather than by dialing in (on another control) the desired
compensation - and the compensation is automatically disabled for the
next exposure (no need to remember to defeat a locked in compensation).
I have never figured out the appeal of auto exposure modes - it is
simpler (since you do not need to add the extra locking step, or
compensation step, or control-resetting step [for a better choice
of aperture-shutter speed relationship] if you disagree with the
auto setting) - manual mode is almost always faster for setting
*accurate* exposure (unless you just follow the camera-recommended
exposure - but most folks here have enough experience to know better
than to do that....;-). (Ummm, same with AF....;-)
Hope This Helps
