Hi folks,
I'm kinda new to the whole Image Stabilisation-thing, mostly because I shoot medium format film.
Lately I'm shooting landscape at night, long exposures with a Canon 5D, mirror up, cable release and tripod.
I don't have a need for IS for most of my work, and also no access to them.
I wonder however if IS stays active for the entire duration of the exposure? This would be useful to negate effects from e.g. a passing train, traffic or a single gust of wind.
thanks
Mike
