i can't resist a reversal, i so often see people say anybody is who isn't prepared to carry a tripod is a pansy or anybody who is serious about iq will use a tripod. i think they just need to drink less coffee.
forgive me for not having much experience with canon's IS, but i thought it was supposed to detect panning pretty well and not compensate on that axis? is that something that doesn't really work in practice or was the eagle just an erratic flier?
I'm really working hard to reduce my coffee intake. I used to start the morning with a quad espresso, followed by a double a few hours later. Now I'm OK with two doubles, early in the morning. After that, only Diet Coke.
Canon IS has two modes. Mode 1 is for stationary subjects; it stabilizes (compensates for) small vertical and horizontal perturbations in lens/camera motion due to trying to hold the camera steady (hand shake, wind, etc.). Mode 2 is for moving subjects; it stabilizes for small purturbations in the direction orthogonal to the track of the subject; provided that subject is moving in a horizontal or vertical plane. Mode 2 works fine for predictable subject trajectories, like at a race track. OTOH, Mode 2 is counter- productive if the subject is moving all over the map. Like a stupid bird!
I find that IS Mode 1 is very helpful for stationary subjects, for handheld and monopod photos, as well as for tripod photos in windy conditions. Mode 2 is great for subjects moving in horizontal or vertical directions, but not for other directions (e.g. moving up and to the left).
So, after using many generations of Canon IS, I prefer to (i) use Mode 1 for a stationary subject, or (ii) turn IS off for moving subjects. IOW, for moving subjects you have to keep shutter speeds up, but that's not an especially new idea, is it.
