Hello all, I recently purchase an a7 with the 28-70 kit lens and am really enjoying it. I am amazed by this camera and how well it works with a few legacy lenses I have. We are planning a trip to Glacier park this summer and I hope to purchase one more lens for this trip. If money was not an issue, I would love a fast wide angle and something with decent reach for wildlife. Money is limited, the legacy lenses I do use are a fd canon 50mm 1.8 and an old vivitar 70-210, given that what would you get for this trip? Thanks!
