Terry,
I agree with you and will add: I use my 500 f/4 IS lens 20% of the time
with both the 1.4x and 2x on my D30 which gives me an effective 2,240mm
f/11 lens. I have never turned the IS feature "off". It cannot hurt
anything and it can help anywhere from a little bit to a whole lot. I
have used this combination with a 1v (1,400mm) on an Eagle in Florida
with 20 mph winds. With IS, over half were sharp. My friend beside me
using a Nikon 600 with only a 2x shot over 100 exposures and none were
sharp enough to keep.
I actually think IS is more important on my 500 lens than is is on my
28-135 and my 100-400 lenses. Mainly because 99.99% of my images are
made from a tripod.
