Bought a Nikon D3300 a couple of years ago. It came with Nikkor DX VR AF-S 18-55 mm 1:3.5-5.6 and 55-200 mm 1:4-5.6 kit lenses (I hope I have identified them properly). I was happy with the lenses but on a trip to the national parks in Utah, I got pretty tired of switching lenses all the time, always fearing I would drop one while switching. I consulted with a local camera shop and they recommended a Sigma DC 18-250 mm 1:3.5-6.3 Macro HSM lens. It's been okay but I wasn't thrilled with it, particularly the vignetting on wide-angle shots. I just compared near-identical shots from each of the lenses and was stunned at how much sharper the shots with the Nikon lenses were, and at how washed-out the shots using the Sigma were. Is this typical? Did I make a lousy choice with the Sigma? I'm about to take a trip to Italy and it doesn't look like the Sigma is going to be making the trip with me.

My mistake - Utah highway 95 went from intersection with Utah 261 (gotta see and travel the Moki Dugway), toHanksville. Goblin Valley S.P. is just outside Hanksville.

Agree with all the above, particularly Arces, Canyonlands, Goblin Valley. Monument Valley is not too far from Moab and is spectacular. Stay in a cabin at The View hotel. If you can do Utah route 95 (I believe) from Capitol Reef to Bruce, it is also pretty amazing. Bryce was my favorite, Arches was my wife's. Goblin Valley was s close second for her.
