Just wanted to say special thankyou for those who shared their wisdom on this subject. Was really appreciated. But to LostPatrol(Simon) a big hug of gratitude. Have worked out due to his knowledge that i have two lenses. One being EF-s and the other Ef. So when i buy my new Canon 5d i can use my main lens for photography. Thats until i save for another lens. Thanks everyone:) Chris
