I really appreciated all of the advice I received on here with my last question so here's my next one…
After agonizing over the sheer number of quality mirror-less and point-and-shoot options out there, I've decided to invest my time and money into my DSLR even though it's the heaviest option available to me.
My current setup is a Nikon D5000 with the standard 18-55 and 55-200 DX kit lenses.
My wife was a photo journalist by trade in the Air Force (pre digital) and enjoys using the camera so between the two of us, any upgrades we make to our system will get used although we are both novice.
With that painfully long preamble out of the way, here's what I'm looking at. As typical for backpacking in the PNW (and most of the US for that matter), I appreciate having the ability to cover a wide range of shots with my lenses and I wouldn't feel comfortable leaving either of my kit lenses at home. So I have two ideas:
Option 1) Nikon will release the AF-S DX NIKKOR 18-300mm f/3.5-6.3G ED VR to the market next month. Apparently it is 10oz lighter than the AF-S DX NIKKOR 18-300mm f/3.5-5.6G ED VR and $100 less. I realize that this is a jack of all trades/master of none lens but in my mind, this lens will be a great compromise of performance, weight, and simplicity for a DSLR. The weight is the same as the 18-200 so unless I hear a good reason why, don't think I'm going to consider that one.
Option 2) Forgo upgrading my glass for the time being and buy the D7100 for a few hundred more than I was budgeting for my lens or a D7000 for about the same cost. I'd then have the option to sell my D5000 to help finance the new camera. The theory with this option would be that I'd be able to take pictures at a higher resolution so I'd just bring my 18-55 and crop pictures (yes purists… heresy I know) as appropriate.
Options 3) I may be missing the boat altogether and I should become more zen like with a single prime lens or other option I haven't considered.
Still trying to figure this stuff out so your expertise and advice is appreciated.
