The only exception is the X1T-F trigger when configured with the custom function 11 set to 2, which makes the camera go to Manual mode. I don’t need TTL, but I do need a feature called High Speed Sync (HSS), which requires a working smart connection between camera and trigger. So, problem solved? Leave that piece of paper in the hot shoe and call it a day? Not so fast. Now, M mode can be chosen on the camera and there is no delay. This prevents the camera and trigger to communicate and negotiate smart modes like TTL and whatnot. All you need is a piece of tape or paper with a small hole in the middle. In that configuration, I can feel the increased delay.Ī simple way to force the trigger to M mode is to block all the pins but the middle one on the flash hot shoe. In this mode, I cannot feel any increased delay.īut when the XPro-F trigger is mounted on the camera, the camera forcibly sets itself to TTL mode and M mode cannot be selected even though the trigger is only associated to the manual-only TT600 flash and the flash power is manually set on the trigger. When the TT600 is mounted on the camera directly, the camera correctly sees the flash as a manual-only flash and sets itself to Manual (M) flash mode. But the key point to remember here is that TTL involves doing things before taking the shot, and this takes time. ![]() You can read more about TTL on Wikipedia. By observing how much of the pre-flash came back “through-the-lens” (TTL), the camera can easily compute the actual flash power to set for the actual shot to get the desired exposure. This works by firing a “pre-flash” when the shutter button is pressed, but before taking the shot. In case you don’t know what TTL is, it is a mode whereby the flash power is automatically adjusted to give a desired exposure. This also gave me some insight into what was the probable cause of the delay: TTL. So, my first instinct was to Google this issue, and sure enough, a few people already complained about this on various forums. Indeed, it seemed like the flash was causing a very slight lag in the shutter response, not huge, but definitely there, and enough to ruin a shot. However, I noticed that when I used the Godox flash and trigger, I often missed the shot. ![]() With some practice though, it becomes easier to nail the shot most of the time. I dabble in dance photography, which requires very precise timings of the shutter release to catch the apex of jumps or things like that. ![]() I own a Fujifilm X-T4 mirrorless camera, along with a Godox TT600 flash and a Godox XPro-F radio trigger.
