I have a Nikon D7000 that I use when I am trying to take serious photos (normally I just drag along a point and shoot). I am trying to get more serious about it and upgrade my setup with a long telephoto for when I go hiking and camping in the Sierra.
My current goto lens is a 18-140mm 3.5 - 5.6. I am looking for a lens in the 300mm range. The shorter end doesn't bother me so much, because I have it covered. However, if there is good value in extending the lower end, I would be willing to spend a little extra money (i.e. buying a 55-300 vs a 75-300). Most of my hiking photos are not action shots, they're landscape and sunset pics. Money is not an issue per se. I mean, I'm not looking to spend ridonkulous money, but nor am I looking for the cheapest way out. I'd like a serious lens that I won't have to upgrade.
For those of you who shoot, what do you use along these lines? Note: I have a Nikon camera, but I'm not a brand snob. If you have a good lens suggestion, I'm open to it.
