Lens for Hiking?
I'm looking for an lens for my Canon T2i when hiking in the mountains. I currently own the Canon 18-135 mm and the 50 mm 1.8. As I'm getting older I don't like carrying a lot of weight with extra lenses and equipment. I've been thinking about the Canon 18-200 mm but someone mentioned the Tamron 16-300 mm. I've also considered the Canon 55-250 mm. Is there a lens with sharpness at the 200-300 mm range for wildlife? Thanks in advance for your help.
