Its universal hotshoe allows the use of most single electrical contact flash units as external light source. It fully synchronizes with fill-in flash and red-eye reduction flash and can be used with virtually most digital cameras in the market. It works as a slave. It ignores the preflash from camera and triggered the external flash by the built-in flash of your camera. (as shown in animation above). Total 6 Synchronization Modes can be selected to suit different delay for different brands of cameras. It is compatible with most digital or film cameras with or without preflash features. Two types of pc sync. terminals are ready to be connected for triggering off the unit. There is standard tripod socket on the bottom allows mounting on bracket or tripod. All units will be tested before posting.

Absolutely Wireless.
Weight (with batteries): 29 grams (1oz)
Pour le TTL j'y connais rien dans ce cas, mais ça parait impossible!

En manuel comment accorder les différences de puissance des 2 (ou plus) flash pour avoir une atténuation homogène d'ombres portées?

Si d'autres connaisseurs des flahs esclaves peuvent donner leur avis sur ce type de matériel et son équivalent dans cette gamme..merci
