want a sound trigger

There is a slight delay with all radio triggers - with expensive Pocket Wizards it's next to nothing, and with the cheap ebay jobbies you have to reduce your x-sync speed slightly, say from 1/200sec to 1/125sec, that sort of order.

However, that is nothing to the delay between tripping the shutter, the mirror rising and the shutter opening - up to 100ms is not unusual for that. But I'm guessing you'll be using open flash.

I never had to go under 1/250s with cheap chinese triggers. What it doesn't do is ETTL-II, and only has a short range of maybe 10-20 meters.
