The handshake between flash and camera is what you're really paying for, and the TT685II-C does it properly. Mounted on an EOS body it meters through the lens with E-TTL II, syncs at up to 1/8000 sec, and follows the camera's own exposure settings instead of asking you to do the arithmetic. Guide number 60 at ISO 100 with a head that zooms from 20mm to 200mm means it has the reach for a dark reception hall and the spread for a small living room.
Two details earned their place in our kit. The quick-release lever clamps the shoe without the fiddly screw collar older flashes use, which matters when you're moving between bodies in a hurry. And the TCM button converts a TTL exposure into the manual power level that produced it, so you can shoot a frame on the meter and then lock that look in for a sequence. That is the fastest route from trusting the camera to overriding it that we've handled on a flash at this level.
Power comes from four AAs. We count that as an advantage on a trip, where eight cells and a charger outlast any built-in pack, and a chore at a long event where you're swapping rather than shooting. If you'll be at full power for hours, a lithium-ion unit is the more comfortable tool. For everything else the AA bay is a fair trade for what this flash does not cost you.
One thing to check before you order: on a body like the R50, which lacks the legacy hot-shoe contacts, this flash needs Canon's AD-E1 adapter to communicate. On an R5, R6 Mark II, R7, 90D, or 5D Mark IV it's a straight fit, and that dedicated Canon E-TTL II build is why we trust it over a generic single-contact unit with the same guide number.
Pros
- E-TTL II metering that speaks Canon's language
- 1/8000 sec high-speed sync for wide apertures
- GN60 with 20-200mm zoom coverage
- TCM button converts TTL into a manual level
Cons
- Runs on four AA batteries
- R50 bodies need Canon's AD-E1 adapter
For most Canon shooters we recommend the TT685II-C: it meters through the lens, syncs to 1/8000 sec, and puts GN60 in the air for midrange money.
