There are a large number of options available to you all over the price/reliability spectrum. You basically just want TTL-capable triggers for Canon. The difference between using them and using manual-only triggers like the V5s, is that you may be limited on what lights or other triggers play nice together, and integrating studio strobes might be more of a ...
If you are storing standard metadata fields such as camera information, it would probably be easiest to stick to the well defined field names and types of EXIF. It may mean better compatibility with other applications that may not have as good support for XMP.
Your other option is to simply use both as they can co-exist in the same file.
Your flash is probably set as slave. Check the switch for master/slave/off next to the flash shoe. It should be set to off, when it is mounted to a camera or to master when it actually masters other ETTL slaves. But unless it really is a slave, mastered by another ETTL master, then it should not be set to slave.
They are different formats. XMP is an XML based format that is more self-descriptive where as EXIF requires knowing the format of the file to know what value is at each offset. EXIF is more limited in what it can store (atleast that can be universally recognized) but also is smaller since it doesn't need descriptors of the fields to be included in the file....
Both Nikon and Canon use ISO-compatible flash hotshoes on their cameras and feet on their flashes, so the Canon flash will fit on the Nikon hotshoe, its sync voltages are well within the limits a Nikon hotshoe can sustain, and the ground signal (rails) and sync (fire signal--the pin in the center of the foot's square) will be recognized and work, so the ...
For anyone who reads this, wondering what solution worked for me, I can answer it with two words: Cactus v6.
I mentioned that I have a few (4) Cactus v5 transceivers as well as a 580ex II and a Yongnuo 560. I didn't know this when I posted, but Cactus now makes a v6 transceiver that is 100% backwards compatible with the v5.
How do they work? The v5 is a ...
Godox has several transmitters in their 2.4 GHz radio system that can trigger and/or control the AD200:
Flashpoint R2 Pro II-C
Flashpoint SPT single-pin transceiver (manual trigger; no TTL/HSS/power control)
XT32 (manual trigger with HSS/power control)
XT16 (manual trigger with power control)
The 580EXII, however, does ...
The flash needs to be set to use its hot foot for communication with the camera.
If you set the flash to 'Slave', it will ignore anything attached to the hot foot and will monitor its optical sensor for optical pulses from an optical master flash (or ST-E2 flash controller). You should set the flash to 'Manual' power mode in the same way you would if the ...
