Hi, I had a Nikon D60 fo a year and am looking for my first telephoto lens for wildlife photography. I do a lot of hiking and want to get photos mainly of large mammals in the Alberta Rockies. I have a 18mm - 55mm lens and got tiny photos of a grizzly I saw last year. Anyone have suggestions on lens? I have a budget that would top a bit over $1000 for a really good lens. Less is always better though. I would be willing to take a second lens for wider angle photos. I've been reading about problems with speed, focus and vibration. It would be great if I could pull out a camera and take a few pics of an animal without a tripod. Is that even possible? Thanks!
