ADVANCED WIRELESS FUNCTIONS FOR CANON EXTERNAL FLASH: Incorporated 2.4GHz makes it easy to shoot with advanced wireless multiple ﬂash lighting, in the same way as TTL auto-ﬂash shooting when using several flash units. Multi-angle and multi-directional photography setups are simple since flash units don’t need visual proximity to one another. The RT-305 manual Flash trigger enables wireless transmission with a manual set up, it does not support TTL mode..
WIRELESS MANUAL TRIGGER FLASH CANON: The RT-305 manual wireless Trigger has 16 channels for communication. NOTE: When using the RT-305 manual wireless trigger with the AP-305 hot flash, HSS and TTL are not supported and flash sync speed will work up to 1/250s. HSS and TTL are only available when using one or more of the AP-305 Flash..
