Questions & Answers

TIMOTHY J : Will this device work with a Canon 430EXII speedlite? Will it work with a Vivitar 283 speedlite?PATTI A : Yes it works with the EX 430 II Speedlight. That's the only flash unit I've tried it with. I mounted the EX 430 II with this DS-1 Slave Trigger on a light stand and used the built-in flash of my Canon Rebel XS to trigger it.MATT W : Most likely but you'll need to turn off ETTL preflash otherwise your secondary flash will go off early. This will throw the exposure and likely result in the secondary flash not firing the second time.ROBERT S : Sorry I can't answer for those parts. I have a Canon D20 and Bower SFD290 flash units and it works well.

works with nikon

I used it with my Nikon D60. It does not trigger on the pre-flash so it works the way I wanted.

Another useless "gimmick"

I found this product very difficult to use.The instructions are very minimal, especially when there are a couple of ways to use this thing. It's manufacturing is also pretty shoddy. The plastic face was already terribly scratched even before I attempted to use this thing. I would have expected more quality from Speedotron, whose equipment I started out with many years ago.

Woks w/ Nikon CLS

This trigger works well with Nikon CLS. This means that it is not triggered by any communication preflashes used by Nikon system. But it triggers well when main flash occurs. I use it with old StarBlitz flash attached in environment where other flashes are SB-900 and D200 pop-up flash working in commander mode. Old StarBlitz fires right on the dot. Just remember to flip the Normal/Digital switch on the trigger to Digital position. Of course it does not convert old flash into i-TTL flash. Just triggers it.

Great product, great price!

Seriously, if you have an extra (old or new) flash and you want to give it some good usage.. get one of this! I have been using it with an old sb-24 (set on manual) on a tripod... and a sb-600 on my Nikon... and it works flawlessly!

Not good

Unit wouldn't work right out of the package. Figured the battery was the problem. Opened the back only to discover that you have to remove the top circuit board to access the battery. Flat, hearing aid type. Two wires were completely disconnected from the board and another popped off while I had the unit open. Cheap construction.

Very good and sensitive trigger.

This is perfect for my needs. It sure beats the Vivitar trigger I have been using.

Great for indoor/nighttime use

Easy to set up. Two switches - On/Off and Preflash/Normal. A couple of times I had to loosen and retighten the flash in the hot-shoe to get it to work. Would like for it to be slightly more sensitive for use in daylight with fill flash.

Works with Nikon and Olympus

Syncs with my Oly c2100 UZ and my Nikon D200. Has switch for digital or film. While both cams are digital the Nikon works on film. Bracket uses flash shoe or 1/4 x 20 male or female. On off switch marked with tiny symbols hard to see.

• This slave with a hot-shoe contact for all portable flash units has been optimized to also work with digital cameras, as ordinary slave units do not work with most digital cameras that use a very rapid series of pre-flashes, that trigger the slave prematurely. It is Sensitive up to 100' (30.4 m) away.

Working as an ordinary slave sensor, which will syncronize immediately with a master flash, the Speedotron DS-1 Digital Flash Trigger is also designed to work with digital cameras that use a pre-flash mode. This slave sensor switches from Normal Flash to Pre-Flash syncronization mode.
