I am flying to Newfoundland this coming Friday for 10 days photographing whales; icebergs; bird colonies; lighthouses etc. Looking to purchase a good wide angle landscape lense. My main long lense is the 80-400VR; 2 other lense I have but do not use often are Nikkor 18-55 AFS VR DX 1:3.5-5.6G, & Nikkor 50mm AF f/1.8D. Still learning and maybe I need a lense about 200mm or so not sure.
