Special support for 2nd Curtain Sync and HSS (mode switch) USB for firmware updates (special firmware required to use the Tuff TTL on a 60D) not really easy to understand? See system chart below (the XPro C seems to close a gap there.): Rebadged Godox X1T-C/X1R-C USB for firmware updatesĬompatible with Godox TT685C Speedlite USB for firmware updates *supports digital channel IDs from 01 - 99 Supports E-TTL, M (≥1/256) and RPT modes, HSS, remote zoom, FEC, 2nd CS USB for firmware updates according to Adorama a FP-exclusive model Supports remote flash zoom control and ratioįlashpoint R2 Pro II C *lithium compatible USB for firmware updates flashes, but only allows for remote manual M and zoom The Canon firmware does not (yet?) support cross-brand TTL with Nikon, Pentax, Fuji, Olympus, Panasonic etc. X-TTL requires the latest firmware update sports a Relay Mode directly fully compatible with Canon and Cactus speedlites (incl. Transceivers with AF assist light (1W LED) The way you adjust the lighting ratio of the flash units is to set the Flash Exposure Compensation of the on-camera and off-camera flash units separately.Cross-compatible with Canon E-TTL, Nikon i-TTL and Pentax P-TTL (only Sony needs a dedicated set) If the flash is used with the camera in iTTL mode then the flash should be in iTTL mode. I am not sure but I believe that in S2 mode the flash also is in the Manual mode and the power must be set manually on the back of the flash with no remote control of power from the built-in/on-camera flash. In S2 mode the flash ignores the iTTL pre-flashes and fires when the iTTL exposure flash occurs. I am not sure but I believe that in S1 mode the flash also is in the Manual mode and the power must be set manually on the back of the flash with no remote control of power from the built-in/on-camera flash. When you have the camera set to iTTL and the flash in the S1 mode the flash fires as soon as the Commander sends out the first pre-flash. When your built-in or on-camera is in iTTL mode it sends out pre-flashes to program the off-camera flash and to determine the correct flash power for what it thinks is the correct exposure. In S1 mode the flash fires as soon as it sees any other flash and is primarily for use with studio strobes. S1 and S2 are "dumb" optical slave modes. Here is a source for the part if you attempt a DIY repair. Symptoms are the flash always fires at full power regardless of its mode or settings. If so you may have a failure of the IGBT transistor in the flash. S2 fires the flash at full power, no matter what power I set on camera OR the flashĬould someone explain me what I'm doing wrong, this is driving me crazy !ĭoes the YN 568 EX do the same when in camera's hot-shoe?.S1 fires the flash, but the flash doesn't light the subject.Flash fires at full power, no matter what power I set on camera Sn is i-TTL it doesn't work well, which can be expected I guess, as I want manual control.Setup Flash in Slave mode, same Group / Channel.Setup camera in flash controller mode / Group A is "Manual".I would like to have my Nikon D810 control the Yongnuo's power with the camera's flash controller mode, as I do with my SB600, which works lire a charm. I'm having trouble using my Yongnuo 568 EX in an off camera setup.
