I'll be doing an inland Alaska trip in June. I'll be shooting landscapes, of course, but I'd also like to get some nice wildlife shots. Budget is $400-$500. I am leaning toward the Nikkor 55-300 f4.5-5.6 VR. Link: Nikon AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR Lens 2197 B&H I am open to suggestions, though. Any thoughts on this lens? Alternative choices? Other advice? Thanks!
