Which Lens Hood for 650D (T4i)?

Hey everyone

First post in the Canon section of the forum so please be gentle:-) (I also have a Nikon 1 V1 which I am playing with also at the moment).

Just picked up the Canon today - the battery is currently charging. I want to pick up a Lens Hood but not 100% sure which type I need / would work on the camera as I can see both petal hoods and regular round hoods.

I am just using the kit lens (18-55mm EF-S IS II) at the moment - will look into better lenses later in the year when I have some funds. I will also look into possibly getting a UV or Polarizing filter too (Hoya are good?) in a few days.

Many thanks for any help:-D

P.S. Can't wait to start shooting with this Camera!
