snch flash query

Fuji S7000
Aperture F8 and speeds as reported by EXIF. Big Cobra external flash on hotshoe plus a Lumiquest Ultrasoft strapped to flash (the flash is a Canon dedicated flash so it's firing at full blast every time)

I'm not suggesting that the camera has a sync flash speed of 1/10000 but something is going on here.
anyone have any ideas?
I had no idea that sync flash even exsisted untila I posted a pic that I took at 1/7000 with a flash (ant farming mark 2 in the Critque forum) and someone told me that that wasn't possible.

Sorry about the dull subject :lol

The S7000 doesn't have a shutter, so the flash doesn't have to sync with anything. The sensor is always on - the "shutter speed" is how long the camera spends collecting light from the sensor in order to make a picture. So as long as the timing is correct the flash will inherently be "synched" to the "shutter speed."

Or something like that.

Makes sense to me.

Thanks

if it has this advantage then why don't all digital cameras use this system?

there must be drawbacks?

[Scottes]

Yes, there are drawbacks.

The biggest drawback is that this type of system isn't SLR - Single Lens Reflex. With an SLR you are looking through the lens at *exactly* the same thing that the film plane (or digital sensor) will see once you hit the shutter. You are not looking at an interpretation of the scene as the sensor show it to you. You are seeing the exact same thing the lens sees. In real-time. To me, that's a big deal.

I'm not knocking the S7000 - my wife has one and it's a very nice camera. It's ability to "synch" at 1/4000 gives me some ideas....

Thanks for the info
I knew there must be some disadvantage.
Being an impatient sort I couldn't wait until I could afford the Canon digital SLR and the S7000 seemed to be a massive bargain.
By the time I've learned some more I will be ready for the digital SLR (whether I can afford it at that point is another matter :lol: )
