Seagull SYK-5 Wireless Remote Flash Slave Trigger with Red Eye Reduction

Suffers from the notorious "flash once and never again" issue. Tried it with 430EX and 600EXRT flashing to each other with and without the camera (5DM2), strobes in manual, switch thrown to "lightning" or "redeye". Always same result -- flash once, and not again till power cycle on receiving flash. Obviously this makes them pretty much useless.Not sure how the others are claiming they got it to work with their Canons.

i have tried to use it with a canon430ex speedlite. cannot get it to flash at the same time as my canon 40d. it has an adjustment but cannot find the setting that works with my camera flash speed.

I got this to experiment with the flash from from my Sony Nex 5N. I am only able to effectively sync an off-camera flash with this with minimum shutter speeds of 1/20. Any less than that then the red-eye correction kicks in and this will trigger the flash less consistently.I guess if you want this to work with the Sony Nex, there should be some experimentation and learning involved before you can effectively use it.

I got this specifically to work with my 430ex II and so far it works like a charm. I have been using this to trigger it while I have my einstein with whatever modifier attached as the main and this becomes the fill.I used this for the first time yesterday on a shoot and I've been really happy with the results. So far I haven't had any misfires at all. Granted it is triggered by any other flash going off at the same time but I'm fine with that. It was either spend the 15 on this here or blow 4 times that on another receiver for my system.The only reason I gave it 4 stars is that the casing on it is kind of weak in my opinion. It hasn't broken on me at this point but I will be sure to be careful with it.Pros:Works like it is supposed to!adjustability works nicely as wellworks with red eye reduction flashes as well.cons:why aren't their any instructions....???Could be built a little more study.And I came back to order some more of these but it seems that they are out of stock all of a sudden, that's a bummer!!!!!

I received the item promptly and immediately installed it on my auxiliary electronic flash and it works perfectly! No brainer to use it as if you have a hot shoe for your electronic flash, merely slide it on and presto --in business(no interconnect cable is needed). I took many pictures with and without it as fill in and tremendous difference!Only draw back was all instructions are written in Chinese; no instructions are needed as it works "right out of the box".

Unfortunately, it was broken when I received it. I was relieved it was only a minor gift and decided not to replace it.

The Seagull SYK-5 does trigger the Canon Speedlite flashes but it is not compatible with Canon Cameras. Reading dpreview.com indicates that is also true for other users. The flash is not in sync with the shutter, apparently no delay options is correct for Canon's pre-flash.

Did not work well for me, but it may have been a user error.
