5580 comes with 3.2 megapixel camera (2048 x 1536 pixels) with 30 fps capacity which is much better facility to avoid the perception of vision (12 fps for human eye). While recording with this camera frames hardly distort even though the direction shift is pretty high.
I passed on from Nokias official website where I found the figures,
For photography 3 x zoom facility is available along with Autofocus on objects (face recognition ) and dual LED flash lights. So you can happily capture the images in dim light without worrying about clarity of pictures.
Flash modes available are On, Off , automatic, red-eye reduction and White balance modes features : automatic, sunny, cloudy, incandescent, fluorescent. According to your needs and fancies you can select the appropriate modes to elevate your photosession.
Some buddies are much worrying about clarity in pictures, believe me it has so many built in features available to balance the modes been selected ofcourse if you turn on the default mode.
This is the picture I captured from 5580 xpress music.

The functions I noted out from gsmarena and fonearena :

• Nokia 5580 comes along with TV Output but this feature lags in 5530.So, connectivity cable in the sales package included.
• 5580 user interface is more improved with better touch sensitivity than 5800.
• 5580 is much more compact than 5800.It’s body volume is 20% lesser than 5800 which makes single handed operation quite easy.
• Better audio quality than 5800 through speakers and headphones.Thanks to the front stereo speakers along with it you can opt for the fantastic noise isolating earphones from senheiser and evergreen EP-630 Though good quality earphones are included in the sales package.
More advanced web browser with potential fast scrolling and support a vailable for multiple windows.
