Правда? :yawn: И откуда же вспышка, сердешная, узнает, что вторая шторка "готова" и ей, вспышке, пора синхронизироваться? :p

По протоколу...
Если вы не в курсе, то раньше на Кэноновских камерах сия функция в тушку не закладывалась. Это была функция вспышки...
Сейчас ситуация следующая:
1. Есть вспышки, которые умеют включать синхронизацию по второй шторке
2. Есть камеры, которые умеют включать синхронизацию по второй шторке
Для срабатывания вспышки по второй шторке достаточно чего-то одного.
Исключения есть, но их мало и сейчас они практически не встречаются.
Вот выдержка из всеми любимого ФАКа.
List of which flash units and camera bodies have second-curtain sync.
Note: verifying this information is difficult, since it’s not listed on all product specs, and I don’t have access to every camera and flash unit that Canon have ever built. I believe this list is accurate, but please let me know if there are any errors.
Flash units which do not support second-curtain sync:
Speedlites 160E, 200E, 480EG, ML-3.
Flash units with external second-curtain sync controls:
Speedlites 300EZ, 420EZ, 430EZ, 540EZ, 540EZ, 550EX, MR-14EX, MT-24EX.
Flash units which can use second-curtain sync when used with any EOS body that has a second-curtain sync custom function other than the Elan/100:
Speedlites 220EX, 380EX, 420EX, 550EX, MR-14EX, MT-24EX.
Camera bodies which cannot support second-curtain sync in any form:
EOS EF-M, 750, 850.
Camera bodies which lack custom functions altogether and so support second-curtain sync only when used with flash units with external controls:
EOS 650, 620, 700, all EOS 1000 series cameras, all EOS Rebel series cameras, all EOS Kiss series cameras, 300, 300V, 500, 500N, 5000/888, 3000/88, 3000N, the IX Lite/IX 50/IX 7*, IX**, EOS 300D/Digital Rebel/Kiss Digital.
Camera bodies with custom functions but which lack a custom function to enable second-curtain sync:
EOS 600, 630, 1, 1N, 1NRS, RT, 10/10S.
Camera body which has a second-curtain sync custom function that works on the internal flash but not on external units:
EOS Elan/100.
Camera bodies with custom functions that enable second-curtain sync on both internal flash and on compatible external flash units:
EOS A2(E)/5, Elan II(E)/50(E)/55, Elan 7(E)/30/33/7, D30, D60, 10D.
Camera bodies with custom functions that enable second-curtain sync on compatible external flash units but which lack internal flash:
EOS 3, 1V, 1D, 1Ds, 1D mark II.
The T90 camera and the 300TL flash unit support second-curtain sync, but only with each other.
* I haven’t been able to find out if the IX Lite/50/7 camera supports second-curtain sync with flash units that have external controls, but since it’s based around Rebel-style technology it seems unlikely that such support would have been removed.
** The Westfall/Overton FAQ states that the IX can use second-curtain sync with 380EX flash units, which lack external second-curtain sync controls. The Canon “Flash Work” brochure, however, isn’t clear on this.
