after 2 week testing TTL CONVERTER I and II now i can say:
1) only the TTL CONVERTER I (first release) give problems with Ys 110 but works very well with YS-90DUO (all releases and also the YS-90 AUTO), Ys120 (like explained in the Compatibility List)
2) The TTL CONVERTER II work now well with the Ys110
For different result with macro or wide angle photos:
is a common opinion that TTL is great with macro shots and portraits but not for wideangle shots. With wideangle a lot of time is will to much difficult for the TTL circuit to read the light on the scene and this will make exposure errors.
I prefefere to use TTL only for macro or for close shots. For wideangle i use manual setting (TTL CONVERTER and camera) infact i found very good the possibility to switch the converter in manual mode and use the power dial on the flash.
I'm very interested in your opinion and maybe if you are using the Converter with differents SEA&SEA strobes you can send us your considerations and some demo shots.
Erik and all,
Ryan at ReefPhoto is exchanging the 3rd Sea and Sea TTL converter I've used now for a TTL 2 converter as we speak due to the recent alteration in the Sea and Sea compatibility list for my Sea and Sea 110s. (Again note Ryan's superior service!)
As said before I had two other Sea and Sea TTL units that didn't operate in TTL underwater (one operated for a few shots in TTL in a test above water but quickly failed in TTL), but they both worked in manual bypass (there is a post with my "frustrations in progress" on this - I'd just as soon move on............ ) :glare: Ryan determined that there were a number of units that were "DOA" out of the box.
I've just been trying the Sea and Sea TTL units out on w/a because that is what my main focus is right now (manatee season). I know w/a with TTL is challenging and maybe not the best use for the unit, but it is a good test because you will know how the TTL behaves in the most changing conditions (shallow w/a with wildly varying ambient/lack of ambient light). I don't expect the unit to be perfect under these conditions (but I was told by someone who knows that this unit works quite well for w/a also), yes Erik I'd probably use manual in these w/a conditions [or when the ambient light is reliable just turn off the strobes of course], but I wanted to see how the TTL works.... . I know the unit "white-outs" I got were a problem with the unit because the exposure, etc didn't change and the light didn't change as several were back to back under the same conditions with wildly varying results. But at least this 3rd unit actually worked in some sort of TTL (the other two wouldn't even sync in TTL), so I thought that was a step-up.....
I was just about to hang the unit up for w/a use and try it on on macro exclusively when I read this post about incompatibility with my 110 strobes. I was very glad to read this post and thank Erik for posting it - it saved me yet more frustration.
So now I've decided to give the Sea and Sea TTL2 a try. I'll be using it next week for 6 or 7 hours underwater probably - if weather pattern arrives as predicted (cold fronts have not been making it down here - this is very bad for manatee conditions and I won't go in those circumstances - but that is supppsed to change)...., so I'll have a good idea of the status then. [Silly me in Florida, frowning at too many 60 degree nights and 75 degree days in the middle of winter......... B) ]
I had to decide if the Sea and Sea TTL unit was worth yet another try-out or just go with manual (and manual strobe operation was never a huge problem for me in the past)......, but I'm "stubborn/persistent" and I like to see things through to some sort of answer/conclusion. But the Sea and Sea TTL units are quite expensive (compared to the cost of the Henrich's alone), and I do think Sea and Sea should have tested them out better as previously stated. Especially with their own strobes.
Also at DEMA Sea and Sea told me that the units are only compatible with Sea and Sea housings. This is probably to cover themselves and honestly they have a point as the salesman said he can't vouch for "other" housing electronics. But I also experienced super distasteful (to me), "hard-sell" techniques at DEMA from Sea and Sea booth and their sponsored seminars this past year (something I'm not use to seeing that much of in the u/w camera world). I just think Sea and Sea could put the attention more on the quality/reliability/truth in print of their products instead of all the glossy "hard-sell" that I noticed. But then that is just my observation of course.
Ryan Canon has told me that the unit will work with the Subal ND20 housing and he personally checked out my housing electronics and the unit and all was well. Now the problem is the new incompatibility of the 110 strobes. Ryan knew nothing of this 110 problem and I do feel for him, having to absorb the brunt of these malfunctions when it is basically a Sea and Sea manufacturing problem. Still Ryan has been most patient with me and this I do salute
I'll let you know what happens. Best & Thanks Erik and Sam and all! Carol
PS - ohhhh, Sam a "melting" problem........? Yuck!
