Hello, you can get the S&S TTL converter for canon on ebay http://www.ebay.com/itm/Sea-and-Sea-YS-TTL-Converter-C-for-Canon-for-Underwater-Photography-/400415016803?pt=LH_DefaultDomain_0&hash=item5d3a984763 //Ola

Hi, any ideas if this could work with the Canon EF15/2.8 fisheye or even Canon EF 16-35/2.8 II ? //Ola

I asked those questions to Heinrichs Weikamp´s site: Can i switch to TTL manual mode with the internal converter? Only by switching the corresponding DIP switch to manual or by bringing a magnet near the REED switch. If i turn the strobes to manual mode will it work in manual mode with the TTL converter connected? No, because the converter can not "see" if the strobes are in manual or TTL. So far i have not got a magnet that works but im working on it. But by switching the camera between AV, TV & M modes and altering the flash compensation in the camera i can get the results i want.

Hello, i got the TTL converter directly from Heinrichs Weikamp: http://www.heinrichsweikamp.net/#/en/oem_solutions/

I have installed the HW internal TTL converter + 3.6V AA battery in my Aquatica 5d mk II housing with nikonos 5-pin connectros, using dual YS-110 and it works great. Installation was straight forward when using the datasheet from HW. Now I just need a strong magnet to enable manual mode from outside the housing. Good Luck

Tried the AV and TV modes yesterday and they work as you describe so that is what i was looking for, strange is that i tried them earlier and they didn´t work but maybe the cables were wrong. P mode doesn´t work but thats no problem, thanks //Ola

Hello, i have just installed a internal Heinrich Weikamp TTL converter in my Aquatica housing for the EOS 5D mkII with 2 Sea & Sea YS-110 and it works fine but there is one problem: I want to disable the strobes to use the cameras exposure metering without strobes but as long as the TTL converter is connected the camera thinks there is a strobe (even when i turn of the strobes or put the TTL converter in manual mode) and the exposure metering don´t work correctly. Anyone know if there is a way to disable the strobes in the menu of the 5D or anything else to do? Thanks Ola
