The problem most photogs have is that the ergonomics are too good...
DO NOT GRIP THE GRIP...
I DON'T CARE WHAT THEY CALL IT...
The camera is not to be gripped, it is made to sit/rest/be cradled in your left hand while the right hand just lightly caresses the 'grip' and squeezes the shutter.
...you may read a lot of people complaining of tennis elbow from carrying the 30d around all day...it is because when holding the camera 75% of their camera holding is done with the right hand...
WRONG...
75% of the weight should be in the LEFT hand...that will give you much sharper results at slower shutter speeds...and save your elbow in the bargain.
That's some really great advice. I'm a beginner myself and this is fantastic. I hold my camera the way you describe it (I had a friend who showed me how) but never really paid much attention to the weight distribution side of things. I did notice however that just by having my left hand under the camera made things tons better.
Now I'm going to try to mess around with the 75%/25% thing!
