My photographing of birds in Asia would benefit tremendously from a
sharp 5.6 1200 MM but at the price of 35 lbs and a year's salary is
not my idea of a 1200 mm lug through the woods lens. This is why I
am so excited by the EOS D30 (which I have). This camera is like a
dream come true for bird photography. Having a camera with a built
in x1.6 difference shooting Canon L glass with 35mm like results has
me pinching myself to remember that I am not dreaming. At the moment
I only have the 100-400 IS which is like a hand-holdable 600 f/5.6
(tripod not always possible in bird pics) the 1.4x 896 f/8 produces
great shots and even the 2x 1280 f/11 can be surprising in the right
conditions. Consider that the new 400 f/4 should produce a great AF
896 with the 1.4x and the 500 f/4 is 1120mm with the 1.4x puts super
telephotos into an acceptable range for us serious amateurs. All
without spending the 60,000 +.
