Hi there,

I've been playing around with my SB-800 today in an attempt to gain a greater understanding on how to use it..

I noticed that when you adjust either the ISO speed or Appature on the camera the distance on the SB-800's display changes. This of course makes perfect sence as adjusting those things adjusts the amount of light hitting the sensor during the exposure...

However when adjusting shutter speed the distance information doesn't change at all (camera in full manual mode here). Shouldn't the shutter speed also affect the distance the flash is effective for?

What shutter speed is 'default' on the flash.... so if it was 1/60 I could work out that if I use 1/120 (or so) the flash would work effectively at only half the distance??

Can anyone shed some light on this?

Thanks

Paul

bump...

anyone?

Paul, you are probably realising now that we have no SB800 masters here Position vacant if anyone would like to apply

The SB800 fires at about 1/10,000 of a sec so your camera's shutter speed has no influence on its power settings. Shutter speed only has an influece on the way the ambient light is recorded.

I also have a question about the sb800

I read about FP mode in the manual which allows the camera to sync up to the cameras fastest shutter speed with compatible cameras.

Im wondering if the d70s is one of those compatible cameras because the manual only gives a breif description, so id like to know if the camera is compatible and if the flash will sync to at least 1/2000th in that mode.

The D70s doesn't support high speed sync, but the sync speed is 1/500 which is fast enough for most applications.
Due to the electronic shutter in the D70 there is a slightly dodgy hack that you can do to manually sync faster than 1/500 - but it's rarely necessary or recommended.

Thanks

I did a more thorough google search on dpreview and found out why. its a damn shame really my Olympus used to sync righ up to 1/4000.

oh well shit happens I guess, also I wonder if this sync issue could be changed to support all speed with a firmware upgrade?
