I'm heading to Alaska (both cruise and inland tour), and planning to bring two bodies: a D5500 (which I like for its size) and my new D7500. I'll bring my 10-24 for landscape. I'll also want a telephoto for animals. My options are (a) carry both an 18-140 and a 70-300, and switch off as necessary; or (b) carry a 28-300. It would be great to not have to switch lenses, but if the image quality from the 18-140/70-300 combination is markedly better than that from the 28-300, I'm willing to.
Would appreciate any thoughts.
