Flash settings

Kit - Canon 50D with a 430EX speedlight

I often use flash in bright sunlight to stop motion.It gives a great effect with kids screaming around on bikes, balls or skateboards... or with a beach/ fishing excursion where the flash just blows out the shadows and keeps the colours vibrant.. For some unknown reason (there must be a reason I just cannot find it) in all 3 manual modes (Tv, Av, and full M) and regardless of the settings I input, the camera defaults to a max shutter speed of 1/250

The aperture is usually at F9 or greater to prevent a blown out sky and DOF.

How do I stop this max shutter default kicking in.

Not familiar with Canon but with Nikon you have to go to high speed sync mode to go above the1/250. If you want it to sync at a lower speed there should be a menu setting for flash sync speed allowing you to set it down to 1/30 or 1/60.

That's correct for the Canon as well. To go above the max camera flash sync, you need to use a canon flash and set the flash to high speed sync.

Here ya go....I googled for ya: canon high speed flash sync - Google Search

Thanks - clearly the main reason for the lack of info was that I just did not know the term. "High speed sync"

Been driving me crazy for ages

Let me rephrase - I knew the term, just did not understand how to apply it or why it acted differently across the different modes
