Hi, I'm planning a trip to the Teton NP and Yellowstone in late Sept. I have a H3D50 and 35-90 zoom but would like to rent/buy a longer lens for Teton lanscape. I've never been to the Tetons before and would like to ask for some advice on the three hassy lens: 120 macro, 210 f4, and 300 f4.5. I will also bring my nikon 500 for wildlife and the hassy will only be used for lanscape. Because of the size and weight constrains I can only rent one of the above three lenses. Any suggestions will be greatly appreciated!
