is there any way to go over my vivitars max sync speed of 1/200 - 1/250? how could one do this?

Look for a high-speed sync/focal plane sync option. chances are it doesn't do that, afaik it's just a manual flash.
You can take your chances and use it off-camera with a higher shutter speed. If the flash duration is long enough, you won't notice an odd half-exposure.

I actually was wondering the same thing. I watched a video on you-tube by snapfactory and the guy did it with his settins 1/250 f18 and it completly blacked out the background outside around the model. Very cool feature but my camera with the flash also wont go above 1/200 with flash. Is it possible he was using an external flash accessory on his camera that I just couldnt make out in the video?

ok I figured out why on mine my sync speed dont go above 1/200. The model above mine has that option in the bracketing menu you can set it to go higher. Mine however dont. Thanks

same here, if i go over 1/200 the pictures start getting black curtains.. so there's no way?

I really use 1/160th as my upper limit. Anything faster than that and i start getting banding...

david hobby from strobist had an ingenius approach to the sync limit. he shot an outdoor scene just above the sync speed limit and with flipping the camera upside down (to basically put the banding on the sky instead of the bottom of the photo) he got rid of it because the sky is ambient or something similar to that ..

I just ran into an interesting discovery about my XSi - I can sync a flash (even at full-power) with a PC cord at 1/320th of a second... @ 1/400th there is a minor band at the bottom but not anything majorly huge that I couldn't easily crop. That makes it ALMOST as good as a D40 with it's 1/500th x-sync...

I accidentally discovered this by shooting some test shots and knocking my shutter speed to 1/250th by accident, then I just pushed it until I got banding. Inspired by what I read here: http://strobist.blogspot.com/2010/01/kn ... -sync.html

It'll be interesting to see what happens when I get some Cybersyncs though, I doubt I'll get the same results.

i did notice that it's really dependant on your ambient. if i go out and take a picture out the windows at F8.0 and 1/500 at iso 400 i don't get banding at all! i turn around, take a picture indoors- there we go.. a black stripe on the bottom. so if you expose close to your ambient i'm not sure what the limit is.. if your goal is only to fill the light and not have your flash be the sole light source.. every sync speed goes.

I guess I should mention I was shooting in a room that usually takes ISO 1600, f/1.8 @ 1/30th to get any sort of ambient

Get Pocket Wizard's MiniTT1 and FlexTT5. I can sync up to 1/8000th without any banding at all. I swear to you. They are just simply amazing.

Good job, you discovered high-speed focal plane shutter mode.
simply put, this is a trick mode, which fires the flash multiple times to prevent banding. It does allow you to use a higher shutter speed, but you lose a LOT of power in the process, and motion does not freeze well with it.

Yeah I "can" sync up to 1/8000 but there is never a reason to. And the light fall off after 1/2000 is ridiculous. But it is a nice feature on a bright day when you want to drop the ambient light a few stops.
