I've had the A900 and lenses for a bit less than a week...about 600 shots.
The build quality on the A900 is not as solid as that of the 5D, D300, and the D200.My particular favorite is the D200: solid, compact, fits my hand real well.First reaction when I took it out of the box: too plasticky.
The on-off switch is in the wrong place (for me)...I'm used to the Canon and Nikon locations. The switch is not very sturdy, either.
The CF card door is flimsy...every time I open it I have trepidations that it was the last time. The slot for the card seems more confined than on other cameras I have owned...I have trouble getting my pudgy fingers onto the release button.
The viewfinder is really great...large and bright..no complaints here. The diopter wheel off to the side is another story. Again, too small for my pudgy fingers.
The in-body vibration reductions works really well. Compensates very nicely for my shaky, 77 year old hands.
The in-body dust reducer sounds and feels real nice...but...I picked up two dust spots the first time I switched lenses...and can't get rid of them.
I have other observations that I would like to make (especially about the 24 MP sensor), but I'm afraid I will use up too much posting space, so I will defer for another time.
