Hey, sorry it's taken me so long to get back to you. I don't check this website often, unfortunately. It really does depend on how serious you are about shooting. If price isn't an issue, then shoot for a mid-range camera. Canon EOS 60D or the Canon 7D would be fine, but if you prefer Nikon then the Nikon D7000 would be the way to go. Nikon's have a sturdier build and feel a bit more solid in your hand, but the lenses aren't as good as what you'd find on Canon's end. I personally use an EOS 60D. I like the articulating screen which is a blessing for shooting video, which Canon definitely trumps Nikon at. If there are any camera shops around, go in and play with a DSLR for both and just see what feels more comfortable. If you're interested in landscapes and architecture, then the lenses you need will have to be telephoto and the aperture doesn't matter because you'll be shooting at low stops to get all the detail you want. For a cheaper entry-level telephoto lens, Canon offers a 70-200mm f/4.0 lens for around $600. I'm sure Nikon offers a similar lens. To complete your outfit, including whichever kit lens you get and the telephoto, I would grab a 50mm prime lens. They usually have high apertures (mine is 1.8), and are ideal for shooting in low-light, and they're cheap. You can find them on Amazon from about $100-$130. That would be the best outfit to carry around, but the 70-200mm lens is a bit hefty. You can outfit yourself pretty well for just under $2000, but I'd suggest (and really, it isn't an option if you're shooting architecture) spending no less than $100 on a tripod. Good luck!
