A mate just bought that. When learning to shoot manual, what shutterspeed should he use (with is on) when shooting at the 432mm end of the focal range, handheld.

at whatever shutter speed he can manage to get sharp pictures
it really depends upon his handholding tecnique

Generally you'll want a bare minimum of 1/100 or 1/125 or faster...

Haven't tried IS at that kind of focal length but I'd estimate 1/125th too. A lot depends if your friend is willowy and liable to blow about in the breeze, or solidly planted with an aerodynamically-shaped waistline !

Agree with scalper. It's a bit like 'how fast should I drive before I'll fall off the road and die'.

Depends on the driver.

I cant disagree with your comment, but (puts neck on the block) I found the figures quoted for my 24-70 lens laughable, needing double the figures quoted for any consistency.

The posted speed limit, of course!

I've used IS on Canon SLR lenses from 28 up to 300mm, and I find it does indeed give me at least the two stops quoted for telephoto work. And that's first generation IS.

Personally I spent a huge amount of time up until my early 20's (i.e. until 10 years ago) doing target shooting of various kinds, that has really helped me shoot hand-held at low shutter speeds. I rarely use more than a 30th for landscapes (with a 24mm or 28mm lens) when using a film SLR and 50ISO velvia, with digital maybe a bit faster as 200ISO seems to work so well. You just need to use the same principles of position, breating, trigger control etc as shooting. And if you think the shot wasn't taken perfectly steadily, take it again.

WRT IS I resolved, after a trip to Africa, two things: I would never buy a telephoto lens without IS, and I would never again buy anything less than a pro (L-series in Canon speak) telephoto lens unless all the reviews were exceptional. I've taken too many photos like the ones below that were ruined by a soft, slow lens... Opportunities like this don't come up often (in fact now I'm married with a daughter they come up precisely never) so the kit may as well be up to scratch.
