I can't tell the difference between an image from an M9, the M240, or many other cameras unless I was told which cameras the photos were taken with. I think many on this and the other fora are in the same boat. And yes, I think that for viewing purposes, a skillful photographer can do a lot more with a 10 mp point and shoot than I and most of us ever could with a 36 mp 7R and the best glass.
I too would like to visit the places in Siammirrorless's photos but that doesn't mean they are good photos that show the real worth and truth of the camera.
Michiel, yes, 36.4 is a lot of point and shoot.
I have young kids that move around a lot and that do all kinds of sports. The a900 is severely tested each time I want to take sports shots of a water polo player, swimmer, or gymnast rapidly approaching - if I am trying to shoot on autofocus. The tracking system for approaching figure is pretty worthless, even I employ whatever tricks of the trade that are out there - if I am shooting autofocus.
If the 7r has a better autofocus tracking system for those figures that are approaching rather than traveling parallel to me, I would seriously consider getting it. Otherwise, I will keep the a900 and then fiddle around with the 7R in January when Marc (fotografz) comes to Miami to shoot my son's bar mitzvah.
