to take it to an airshow next weekend, but I have a feeling that a new model will be announced very soon! And it doesn't help that B&H offering 5% off thru live.com or J&R 15% off!!
FL from 120/150/200 to 400/500/(600?!!) at f/4-5.6, with newer IS and faster focusing, weather sealed.... it's just around the corner, I can feel it!!
My wonderful 70-200 2.8IS becomes so blurry with my cheapo Pro Optic 2x extender... worth getting a Canon 1.4x or 2x extender for the airshow? What do you think??
