I use the flash trigger with a Canon EOS 650D and the flash Nissin Di866 Mark II. It is now possible to control prima all about the built-in flash control of the camera. This is very comfortable to find its optimal settings. But particularly suitable TTL transmission is also when operating event photography and the flash used unleashed. In addition, you can now use the high-speed sync, that I may illuminate together with the flash triggers under a 1/200 second. So you can freeze many moving subjects, unleashed of course.
The trigger will be operated by each 2xAA batteries which hold subjectively very long. Practically here is also the on / off switch when not in use. Furthermore, the AF-assist illuminator is really helpful if you focus in low light.
Processing I emfinde for this price, even if it is my first flash release, simply sensational. Since some manufacturers can really abschauen something that is at such a price feasible. The packaging of the trigger was impeccable. Each trigger has been wrapped separately in bubble wrap.
Schön is the catch when using the shutter on the camera. The case seems durable and I would like to point out that only the top of the shutter release button is held in high gloss. This I find important. All the controls are on the other hand kept in black matt plastic.
Tip: If someone like me, finds difficulty communicating from camera to flash, so helped me to reset the flash to the factory settings.
