hi all,i recently got a 70d and i decided i would give a 3rd party flash a try with my new toy,i got a good deal on a yognuno 560 iii,now i understand i should have read up more on its usage before getting it but it was a good buy at the time,i got it to work on camera in manual mode and off camera using my built in flash to trigger it,now my question is do i need a transmitter to send a signal so i can use it off camera without using my built in flash,the 560 iii has a built in receiver,using the flash menu in the 70d theres some settings for wireless channel etc but i couldn't get it to work,after reading on here it sounds like i need a 622 transmitter,do they sell the transmitter by itself with out a receiver as the flash has one already,is there any other options for the set up i have,thanx for any info,this site is great,
dave
