I am talking after a piccy has been taken - with the Cybershot you could focus on things in the background in great clarity - just dont get that with the N900
First of all welcome to the world of photography.

What you're talking about is Depth-of-Field(DOF) and bokeh.

The smaller the aperture (the higher the F-number), the higher the DOF, i.e. the sharper the background.

Cybershot has F-number ranged from F3.5 to F4.6 (generally), while N900's camera has fixed at F2.8. You can see the N900 has shallower DOF.

Just fyi., in general the low the F-number a lens could attend, the more expensive.

However, I did't mean N900 has better lens. I haven't done this kind of comparison yet.

Bokeh is the blurring effect in the background AND foreground. The better the lens, the bokeh would look more natural (or unnatural).
