Questions on sony f828

Hello everyone !
My name is vick btw and I'm new here ... nice to meet you all !

I have a question on Sony DSC F828 cameras. I currently have one and I was curious if there's any way possible to change the lens of the camera ? I saw a few F828 on the net with different lens and was just wondering :)

And if I can, what lens do I need to get so I can better use a wide aperture to obtain bigger differences between clear foreground and blurry background :) I am somehow in the process of learning and I still need guidance :)

Sorry for asking moronic questions !
Best wishes,
Vick.

It is more practical just to purchase a camera with the lens you need for a PS. The reason is the camera uses embedded software which can't easily be changed and the physical changing out the lens would require machining do to the differences in mounting. Basically if you want to change lenses purchase a DSLR or SLR type camera.
