Looking for some wisdom on a new lens. I have a d5100 with just the kit lens. I enjoy photographing mostly landscapes and architecture. This June I will be climbing Mt. Kilimanjaro and also be doing a safari. I realize the safari and mt. climb would fall under two different kinds of photography. I'm mainly interested in a lens recommendation that would be best for capturing the landscape of the mt. climb. I'm looking to spend no more than $300.
Thoughts?
