get the nikon AF-D 80-200/F2.8, AF-S 80-200/F2.8 or AF-S 70-200/ F2.8 VR... you won't go wrong. There are a couple of AF-D 80-200/F2.8 and a AF-S 80-200/F2.8 for sale in the B&S thread. So go take a look. The speed, built and image quality is very good for 3 lens. AF-D is a bit slower as than the 2. The nikon price is higher but it is only a one time investment and you won't regret getting either one of them. Take your time to go throught and dun rush into buying.
I am selling off my AF-D 80-200mm/F2.8 in the B&S threa. Let me know if you are interested... ;p
