Hi: When I return to the Canadian Rockies, in September, for the fifth time, I'll be taking my new 300mm f 2.8 af-s vr with me. Usually I shoot some landscapes with my 18-70mm. Have any of you nice folks done landscape shooting with this tele? I am interested in trying to isolate interesting features in the mountain scenery and have high hopes for this lens... as it has pleased me enormously with my bird photography. thanks, Chuck / Montreal.
