High Speed sync with Off Camera speedlight

[neuroanatomist]

If the 7D onboard flash can do HSS

Ahhh...but, the 7D's onboard flash cannot do HSS.

It's not the easiest way to do things Bob, but if I need to use a higher shutter speed than 1/200 (5D2) and I'm using off camera speedlites I just frame the shot a bit wider. Then you can just crop off the curtain shadow in the frame and it's back to normal.


Not quite the same as having HSS but I have used it at times.


Just a different way of doing things I suppose if you're interested.


Cheers, Ben.

I'm sorry, but this quote does not explain why the ST-E2 can use HSS and the in-camera flash can't. HSS isn't dependent on wavelength.

You're right. It doesn't explain it and my choice of words was incorrect. But I still think this got something to do with the fact that the ST-E2 can handle HSS and the on-board flash can't. I'll rephrase my lines.


Anyway thanks for informing me.

Sorry, couldn't help it. UnlikeShea, I did read your post (twice, in fact). HSS only works with the Speedlite in the hotshoe mount. It doesn't work via wireless, and it doesn't work via a PC sync cable.

Thanks John- A simple mind, needs simple answers---And you delivered.

Good idea Ben, I hadn't thought about that one---I will have to give it a try.

[bob williams]

This one is very helpful.

I read it---Good info here, Thanks Jan.

[bob williams]

In theory as I do not have much time with the 7D and have never used it with a flash.

Then why answer Bob's question?

I read it twice, but with my bad eye. My good eye was making oatmeal. Congratulations you're still the top forum nerd. -S

I read it twice because Bob seemed to feel the need to repost his question after you 'answered'. But, I think you made the right decision on where to focus your attention, or else you might have burned your oatmeal. Sorry if I offended, Shea. If actually posting a correct and helpful response makes me a nerd, consider me nerd-ified. [img]/emoticons/emotion-15.gif[/img]

Shea, John, Have one, two, three [B] on me.


Thanks,

Wow, F up round here &amp; get quoted up the A! The oatmeal &amp; beer were delicious BTW - Thanks.

It wasn't much, but it summed up everything you probably wanted to know. Glad I could be of any help.


Good luck shooting with the speed of light! []

Ben, I tried this technique today----Didn't work with the 7D because when I set up for off camera flash, the highest shutter speed allowed is 250. Of course, if I set up to use the higher shutter speeds, the off camera flash won't fire. I couldn't figure out how to get past this.
