i just realised that sony/minolta slr has the shutter release button behind the main command dial (layout #1) while EOS and nikons have the main command dial behind the shutter release button! (layout#2)
personally i layout#2 because it feels more natural: as in while gripping the camera, your right index finger is both engaged in both part of the gripping and also AF-ing at the same time, being in position ready to fire away.
when i tried the sony alpha and the dynax, while AF-ing away, i can feel that the right index finger is in a contorted position. (forced to bend backwards appreciably). equally uncomfortable is when u are just gripping the camera, u will want to and tend to relax the right index finger for a natural grip, but the right index finger cannot really be placed on the shutter release button because it will feel contorted.
