Yongnuo YN-468 max speed 1/250?

Hi,

I just nipped out to take some images of birds at my feeder when I noted that with the Yongnuo YN-468 attached the max speed I could get as 1/250s - if I went higher it would always snap back to that once the shutter was pressed.

Is this normal for all flashes (very new to external flash), but having thought to look for it it does the same thing when using the inbuilt flash too.

Cheers

That is the "sync speed" of your 7D. To go faster, you need to enable High-speed sync on the flash (if the flash supports it)

It is a limitation of the shutter design of (D)SLR cameras.

Ah, sadly it doesn't look like its supported on the 7D as its greyed out in the menu

Guess I should have gone for the much more expensive Canon ones if I want to go that fast.

Thanks for the info though.

"The YN468 has a sync mode button as well, unfortunately there is no HSS setting available. But there is another option to activate high speed sync apart from setting it on the strobe itself: you can change the sync mode in the camera menu, navigating to the yellow menu group, “Flash control” and then “external flash synch. setting”. And yes, with the Yongnuo in the accessory shoe you can switch the 40D to Hi-Speed too! Unfortunately, it instantly jumps back to “1st curtain”, so no high speed sync available. Sad news. But not unexpected."
