I'm in the market for a wide zoom. Of course, I'll be using it for plenty of landscape shots as that's most of my photography, but I also want to take interiors of buildings/rooms. So I'm kind of the mind of, "as wide as possible". That being said, I'd like your opinions of the various wide zooms. Keep in mind this will be on a APS-C sensored D80, and I don't intend to go to full frame anytime soon, if ever.
I was pretty decided on the Nikon 10-24. The few reviews out there so far are pretty favorable, but I want to at least consider some of the 3rd party lenses. The others that I'm considering are the Sigma 10-20 or the Tamron 10-24. I've ruled out the Tokina because it only goes to 11mm and it has a very small range.
I made $100 shooting pictures of a hotel. They liked the pictures I was able take using my 18mm lens. I suspect I could produce some better images with a wider angle lens. The company that owns this hotel has 10 properties around the Southwest. I think I can swing a deal to visit each property and take photos for them. So if I can get them to pay me ~$100 + travel for each hotel, the lens can pay for itself (even the Nikon).
So should I get the Nikon lens or should I get the Sigma or Tamron and put the $$ saved towards a macro lens (the 105 VR is what I have my eye on)?
