I would like to keep it between $2-400. I plan on using this for a wide variety of shoots including wildlife to buildings and even a fashion show. So as you can see pretty much just an all around good...

I am looking for a lense that will give me some good distance shots. The ideal shot would be at about 500-800 ft and I have searched, but really I'm not sure which may be the best bang for my buck. :D
