Doug,
Thank you very much.
That information on sensor design is very interesting and something of which I
was not aware. It adds one more attribute to my decision matrix.
A quick look at the Leitax Leica-glass-on-Sony-body web page suggests that it
yields aperture priority functionality, focus confirmation and body-mounted
image stabilization, some of the things that I think an R10 should have.
In addition, DPReview.com gives the A900 a glowing report as an excellent basic
digital camera, one without all the whiz-bang bells and whistles that
needlessly (in my humble opinion) clutter up other cameras.
I am grateful to you for the info and now have a lot more looking to do!
All the best,
Bill
