Input:
I got this lens for the express purpose of shooting distant subjects and subjects it is not advisable to get close to.  That means vistas well out of reach and skittish wild animals.  I am using this lens with a Nikon D5000 DSLR.  It does a good job in still photography, but even at the 70mm setting you have to be fairly well back from your subject.  There is a manual focus ring up close to the camera body, and I found myself inadvertantly moving it when shooting video.  The autofocus feature of the camera worked well with this lens.
