I wonder if anyone tried out yet the new Sigma AF 1.4 x (or even 2x) teleconverter in combination with Nikon AF 80-200 2.8 D lens? Since third party manufactures are the only option for obtaining relativly good quality and AF with TC's on Nikon lenses (teles) I'm interested in buying that piece of glass. Sugestions, pros and cons are welcome, of course. [EMAIL PROTECTED]
