Here is a link to the specifications for the two cameras:
You can read a complete review of the SD900 and Z1000 by clicking on the green link just under the photo of the camera.
Note: Casio has announced the Z1050.
Don't know if it is in the stores yet.
I need a comfortable everyday camera for; 1)pictures in hospital setting (with close up detail capability), 2)vacations and leisure. I like the supercompact's. The canon seems to get better reviews on picture quality but the casio bests it in design and ease. What are your thoughts? Also, I am open to other cameras in the supercompact category if better fits exist for my needs. Thanx in advance.
