Hi Wayne.. understand that they make ettl for Nikon.. and its 50.00morethn ittl.. just wondered if the more expensive version was necessary.
I do not know about that, but I am extremely skeptical it can be correct. I would like to see a link about what we are discussing?
Nikon is iTTL, Canon is eTTL.
Both Yongnuo versions are about the same price (both around $115 on Ebay, with free shipping from Hong Kong, takes a couple of weeks), but the various US dealers importing a good thing for resale mark the price up in different amounts. Around Jan 1, I bought one for Nikon with Amazon Prime shipping for $107, but the price is varying a lot more now. Sometimes varying every day.
The Yongnuo YN565 has both Nikon and Canon versions (the hot shoe pins are different, and the iTTL / eTTL hot shoe protocol is different)... you need the right version flash.
But it turns out that the SL slave mode to work with the wireless commanders has a menu to work with either Nikon or Canon, or even both at same time. So in this one Yongnuo case, remote SL slave mode can be compatible, but hot shoe use is NOT compatible. Buy the correct model.
