Sea&Sea YS-250 Pro, TTL or not?

I am looking into buying a set of Sea&Sea YS-250 Pros, and am wondering what to make out of the TTL capabilities of this strobe.

The ad says: "YS 250 Pro TTL Strobes", and the Sea&Sea homepage says "Exposure control: TTL, Manual(Light-level control)".

But then again, I find all these references online to a "TTL converter for the synchronization between the YS-250 Pro and Nikon".

So anyone who knows about this?

1. Are there two different models of Sea&Sea YS-250 Pro strobes? One with TTL support, and one without?

2. Is there any "build-in" TTL support at all? If so, why do I need a converter? Is it for a different TTL protocol of sorts?

Thanks!

I believe there is only one YS-250 strobe model. The TTL converters are different for Canon and Nikon. The converter is special to the YS 250 also. The version for other S&S strobes is different I believe. I have used the converter on my 40D and it works fine for macro and fish images. I haven't tried it for wide angle type shots where TTL struggles. I have to admit I still shoot manual even though I carry it with me. One of these days I'll give it a try.

Thanks Steve.

I guess my question should be, do I need this converter to have TTL with Nikon? Or does the strobe itself obey TTL instructions from my Nikon camera? I just dont quite get what this converter is for.

Thanks again.

Yes, you need the converter to shoot TTL (iTTL) with nikon digital cameras. The TTL supported by the flash itself is for film cameras...

Thanks davichin!
