Re: Shutter lag

I'm not aiming to compete with video, I'm trying to do what video can't: namely to freeze very high speed motion with high image quality. Camera flashes can produce light pulses much shorter than a millisecond - how much shorter we'll see when my photodiodes arrive.

Have fun of course but its all available on the web:

water drops are all the rage right now and you need this information to capture them. Unfortunately, the lag in Canon DSLRs is not predictable enough to hook it up to fire and trigger the flash at the right time for events that need to be in the right place at the right time when you get down to 1/30000 second. you have to open the shutter in bulb mode and then trigger the flash separately.

If anyone know how to get a Canon camera to trigger at a lag that is predictable enough for this kind of thing, I'd love to hear about it. the most consistemt timing is with all the extra variables disabled like like lifiting the mirror (use live vew), exposure calculation (use manual), etc. but the cameras are still not consistent enough.
