350D - цифровая камера, а даже из названия фенечек видно, что они для пленочной TTL.

This system works with TTL only - A-TTL and E-TTL are not supported. In fact, a whole slew of flash features are not supported if you use the TTL Hot Shoe Adapter 3 cable system. You can’t use A-TTL or E-TTL, there is no preflash, second-curtain sync does not work, the DEP mode will not work, program shift won't work, automatic flash head zooming is disabled (though manual zooming works if the flash supports it), the aperture and coupling range data is not displayed on flashes with LCD panels and the AF assist light does not work. These features are all disabled because their control signals a) are all sent down one line and b) would result in contradictory instructions from multiple flash units.

The TTL Hot Shoe Adapter 3 cord system is really only useful for older (type B) bodies and compatible flashes. In fact, the cord system doesn’t work at all on E-TTL only cameras like the digital 1D, 1Ds, D30 and D60.
