I haven't tried the Dimage 7 but I've read a fair bit of
information about it.
I think the most appealing aspect of the D7 is it's lens and the
fact that it has a manual zoom ring which gives it the feel of an
SLR. The D7 also has a variable focus feature where you can choose
the point of focus using a cursor instead of aiming, half press the
shutter button and recomposing.
The downside of the D7 is obviously it's price. Another thing is as
mentioned by many others , it's battery life. It may be
advantageous if you're travelling and don't have any acceess to a
power outlet since you can pop in any conventional AA alkaline
batteries into it.
I have two NP-80 for my 6900 which is more than enough for a whole
day of shooting in most circumstances, so if I ever go travelling
to some unknown destination, I probably get myself another one, and
I'll be ok.
My personal opinion about the D7, .... well, .. I really don't like
the shape of it, .. it's kinda akward. It also feels very plastic
unlike the 6900 which is egronomically well constructed and robust.
I really love the shape and feel of my 6900, ... it's very solid
and it looks a lot more edxpensive than it really is.
Hope this might help a bit ....
