I am just purchased a Nikon D7000 and would like to purchase a zoom lens. The zoom would be used a lot to photograph schooners and other boats at regattas. I have the lens that came w/the D7000 and want to avoid switching the lens especially when I am on the water. Would I look for one with the VR feature? Would this lens work--AF-S DX Nikkor 18-200 mm f/3.5-5.6G ED VR II Zoom Lens. I am not a professional, just enjoy photography. Also, when I see lens for sale, some say USA and some Imported. Is it okay to get the lower priced one...imported? Do you think this lens would have enough zoom for me? I would like to spend about $600 or $700 for the lens. Thanks.
