Yeah - I am not 100% sure how I feel about the integrated extender. I wonder how (if at all) it can be disabled and if a 2x extender may be placed on the lens.

I am also very curious to see what the price tag on this baby will be. I currently have the money saved for a 300 F2.8, but I may reconsider. The ability to zoom is a nice thing. :P
