Thanks everyone. I've jumped on the $1,899 deal for the 70-200 mm f/2.8. Concerns about its size, weight and if it is really the best option for me linger a bit, but I'll evaluate it over the next couple of weeks. I'll pick it up Friday. And while I am likely no longer in the market for a new lens, feel free to mention some of these older manual focus lenses that are well liked. I know nothing about older lenses and if they are inexpensive enough, I may give one a try. Especially for landscapes.
