Philip Harle 0 Posted July 15, 2007 I saw this thread: http://wetpixel.com/forums/index.php?showtopic=19823 I have exactly the same problem with my Canon Ixus 850IS (called something else in the US, for reasons known only to Canon's "added annoyances" department). The camera clearly pre-flashes, and I have the following results: Manual 1 mode (which is supposed to ignore the pre-flash and fire with the main flash) - doesn't flash at all. Ever. Ignores both flashes. Manual 2 mode (for cameras which don't pre-flash) - flashes with the pre-flash, so that by the time the shutter opens it is dark. TTL mode - occasionally fires a double-flash with fairly random results, occasionally properly exposed. Manual 2 mode with camera set to Flash Exposure Lock (as described in the thread above) - seems to fire correctly, with output adjustable using the dial on the strobe. But it's very annoying having to activate the FEL mode every time you switch between play and manual modes. This is clearly a "work-around" rather than a solution, which is annoying with £1500 kit! Anyone have any ideas? Has anyone successfully operated the Sea & Sea YS-110 with a Canon compact digital? Has anyone successfully operated one of these cameras with any strobe whatsoever? Or should I give up with the 850IX and get a housing for my 5D instead? I only just bought the strobe so could return it to Cameras Underwater and replace it with another one if that would be better. Got to be quick though as am off on holiday on Saturday! All help much appreciated Philip (www.virtualtraveller.org) Share this post Link to post Share on other sites

Got to be quick though as am off on holiday on Saturday!As per my reply on Digigreen, I dive with a guy who uses a YS120 with an 850is and - although he does have 'complications' with this setup, it does work. I know it's not ideal and is still another work around, try running the strobe in 'manual 2' mode with the strobe power output set to 50% rather than full power - as per my mate's setup, you may find that the strobe will suddenly start working with your camera. Quite why it works in half power but not full power is still a complete mystery. If you want to get a more pernament 'fix' for this issue, I honestly think the only solution is to speak to Sea&Sea direct - their boffins in Japan are sure to have tested the YS-110 with Canon compact cameras so they'll be aware of any problems. Personally I suspect there isn't a fix for this... Share this post Link to post Share on other sites
Islandbound 1 Posted July 16, 2007 I didnt have time to formulate a reply earlier but like Bardo's friend, I too have the same 50% solution. I have been using a YS110 as a slave optically fired from a DS51 and have the DS51 set to -1 to make the YS110 fire. If the DS is set to a higher output the strobe wont fire at all. Once the YS fires it is a very bright strobe at full output and I usually end up setting it at about half power for macro shots on a D80 at F18 with a 60mm lens.
