An interesting study on Camera Shake...
Re: An interesting study on Camera Shake...
Interesting read. It looks like any shutter speed faster than 1/125 IS doesn't do much for ya.
I wonder if that is typical for all IS lenses?
The reason I ask is I am in the market for a new super tele.
The IS model is $500 more. If I shoot at 500mm with 1/1000 SS minimum, does IS not help?

IS/VR is only useful at slow shutter speeds when there is a risk of camera shake.
As a general rule for 24x36 film this is 1/the focal length of the lens. For APS-C multiply by 1.5 to be on the safe side. As he was using a 50mm lens this means 1/75s which is close to what he found.
If you shot on a 500mm at 1/1000s hand-held then the IS would probably not have much effect.
Re: An interesting study on Camera Shake...
Yeah I remember that rule 1/focal length, but I can usually do a lot better than that even without IS, maybe I just have extra stable hands. I even shoot 400mm handheld at 1/125th and get sharp pics (though I usually stay 1/250th+)
TF - good article, but I wonder whats the reason he chose a standard angle instead of a like 100mm or something. I am surprised theres a difference at 1/100-1/50 on that lens.
