Is this lens safe to use with this body? Recently, while visiting a friend, I discovered that he bought a new 70-200mm f/2.8G ED-IF AF-S VR Zoom-Nikkor for his D70s. It is quite heavy and I wonder if that lens is safe to use without a tripod with that body. It's an odd match and I never found out why he bought that lens and not, say, the 18-200mm f/3.5-5.6 G ED-IF AF-S VR DX Zoom-Nikkor, which I think, while still a bit of a mismatch cost wise, would be a better match for that body.
