Hi There ;

I am interested in digital photography.
I already have a Camera that it says its 8 Megs but the clarity of the 
photos are not so sharp and details are missing.
I would like to buy a camera that would do Auto/Manual functionalities as 
well as portrait , landscape ,sephia ,....etc
Obviously resultion (no of pixels ) is the wrong charactersitic in a camera 
that I should be looking for.
Q1: what should  I be looking for ?

Q2:
this camera http://www.trademe.co.nz/Browse/Listing.aspx?id=63292802 says
 "It features a High quality 5.36MP Panasonic Sensor, which always gives 
crisp, detailed photos and Megxons modern Interpolation allows the camera to 
take photos at a MASSIVE 10 Megapixel resolution."

which is the effective resolution the 5.3 or 10 ?

Do you recommend buying No frill  Cameras liek this ? or am I better off 
buying something like Canon or Nikon or ... that are more popular ?

Cheers
