I just got the sony A100K,

I too would love to take wildlife shots and shot of horses. would the lens you have that goes to 400mm, do you need to use a tripod for that lens or are you able to hold the camera with that big of a lens on it.

sorry if that sounds stupid, I am just getting into this a bit and want to buy an extra lens for the camera.

do you have any photo you could show us that you took with that lens.

where would I find that lens?
