Underwater off-camera flash for Canon S100, S120

<p>Canon <strong>PowerShot S100</strong> + <strong>WP-DC43</strong> Waterproof Case for PowerShot S100<br>

Canon <strong>PowerShot S120</strong> + <strong>WP-DC51</strong> Waterproof Case for PowerShot S120<br>

What are the best options to have two (2) off-camera underwater (scuba diving) flash for either or both of the above two configurations?<br>

Price is not a factor, but small size, portability and reliability, power is very desirable.<br>

Thank you!</p>

<p>You are going to need an arm and tray set up with two sets of arms if you use 2 flash units. For that plastic Canon case you will also need a kit to velcro a fibre optic cable over the outside of the case in front of the pop-up flash and a second cable to connect the two flash units to each other. Those plastic cases are really more for snorkeling imo. I looked up recommendations for UW packages for the S100 at Blue Water Photo and they recommend the Sea & Sea YS-01 Strobe and the Recsea housing.<br>

<br />I'm not sure of the specs for the S100 but I do know that other Canon cameras notably the G series had some serious negative limitations when it came to using flash, which is why I switched to the Sony RX 100 series in a Nauticam case. The Sony syncs the flash to any shutter speed, the Canon I was using (G12) did not. Also more importantly when you switch the G-12 to manual settings which is pretty much mandatory underwater imo the camera disables the TTL function forcing you to use manual flash setting and guess at an exposure. <br /><br />I have used a single Sea & Sea YS-110a with both the Canon and the Sony and it has proven to be a reliable flash unit. The current equivalent model would be the Sea & Sea YS-250 strobe for underwater photography.<br /><br />Before my next dive trip I am picking up one of these to go with my original flash.<br /><br />I tried to cut and paste links to the flash into this reply but PN seems unable or unwilling to comply. Do a search for Blue Water Photo they have a lot of good information available on their site.</p>

 

<p>z t,<br>

I haven't been in the water for many years, too many to discuss. However, along with Sea & Sea and the other manufacturers that Gordon has suggested, you might also look at the Ikelite website which I do see has U/W stuff for both your Canon PowerShot models.</p>

<p>Might be worth taking a look at their site as they may also have some good information.</p>

<p>If the link will work, . . .<br>

ZT I would call Reef Photo. They should be able to help you with an appropriate set up.

Good hunting.

<p>Thanks a lot!<br /> My question relates to use the Canon S100/120 (no annoying touch screen in these models) as a secondary UW and/or easily portable UW camera.<br /> I use the Nikon D3 series with Aquatica and Ikelites -- it is absolutely awesome workhorse, but sometimes just prohibitively heavy and/or bulky. So I need the best alternative in a VERY small and portable version.<br /> More opinions are appreciated!</p>
