I am going to iceland for about a month to cycle. As you can image I want to bring my camera along with me, but I don't want to bring too much weight with me. I have a Nikin F80 with a pretty heavy lens (sigma 28-105 I think). Since I will mostly take landscape photography I was thinking about a Wide angle lens since they are much smaller and good for landscape. I don't have one and I would like to buy one (perhaps used). Anyone could give me some sugestion on what I should buy or do.
