Купил Sto-fen Omni-Bounce

Планирую использовать с Metz MZ 54 и Canon EOS 20D
Попробовав, пришел в полное недоумение. Если на вспышке стоит Боунсер, то фотографии получаются пересвечеными (снимал в AV и M режимах), результат одинаков как в eTTL, TTL и A режимах вспышки. Поднятие/опускание головы вспышки на результат особо не влияет.
Сняв же боунсер – все экспонируется на ура.
Странно все это. Или я чего-то не понимаю в TTL…
Что я делаю не так?

Похоже проблема во вспышке :(

I have some trouble with the combination of an EOS 30, a Metz Mecablitz 54 MZ-3 (with SCA 3102 adapter), eTTL and an omnibounce. Theoretically this should work without problems. The combination without the omnibounce works fine but the addition of the omnibounce results in heavily overexposed shots (+ 3 to 4 EV’s) and considerable loss of range. The choice of just TTL and omnibounce works flawless. Has anyone experienced the same trouble and/or what can be done to make the combination work properly with eTTL?

Although I have not studied this effect extensively, I see the same (or similar) results on Canon D60 and 10D digital SLRs using E-TTL. The Omnibounce cuts down the light output of the pre-flash. Thus, I suspect the camera is tricked into thinking that it has to put out much more light than is really necessary, resulting in overexposure. In "A" (auto-thyristor) mode, the Metz uses its own on-board sensor to determine when enough light has been reflected from the subject, and is thus not fooled by devices that reduce light output.

Re: Пересветы с Omni-Bounce на Metz MZ 54 с Canon EOS 20D
sb-800 реагирует на надевание баунсера (опаловый колпачок), на ней есть небольшой переключатель, т.е. она аппартано учитывает его. Metz может не учитывать, отсюда и ошибки.
