I own the Sony A77 and the Tamron 18-270 it is a great camera and a so so lens. If I could make a suggestion, since you do landscape why not go for the Tamron 17-50mm it is a better lens I also have the 10-24mm lens which is great. The larger barrel of the 18-270 seems cheap build and it gives average pictures.

I'm an amateur landscape photographer and have a Sony A65 coming in today. I like the concept of a 18-270 wide to telephoto lens. Reviews on the new Tamron with PZ drive seem good. Anyone have comparative experience with the Tamrons and/or the Sony lens?
