Well.... learned a thing or two yesterday.... this is why the T7 is NOT going to work as a camera trap camera body if you want to use good fast SB28 flashes... just about every remote trigger won't wake them up on the first click because of this issue also... pretty lame move of Canon in my opinion. The T6 will work because it has the center pin, but it also has a smaller sensor
