1. What is the use of ISO setting? What is the difference between using 50,100,200,400?

-->The higher the ISO the less exposure time is needed.
eg. Under the same Aperture F5.6
ISO 50 1/60 second
ISO 100 1/125 second
ISO 200 1/250 second
ISO 400 1/500 second

2. For the shutter speed:
if i use 4s, do i have to wait for 4s after i press shutter button for foto to be taken ??

--> Yes within the 4 seconds don't touch the camera. Use self timer or remote control and set the camera on tripod for a 4 seconds shot.

3. How do i know when photo is taken ? Other than seeing the foto on teh display afterwards .

--> Usually there is a blinking red dot on LCD indicating it is exposing.

Have fun,
Happy shooting !
