Yes there's plenty of stuff to point a camera at in Norfolk, I waste a lot of my time doing so! Depending where you are in county you might do well to visit the camera shop in East Dereham -
http://norfolkcameracentre.co.uk/ they are very helpful people in there and will let you try out the lens on your camera. They have a huge range of Canon lenses and often have good secondhand stuff in (though it doesn't last too long).
