I bought this, but I switched to a Canon camera as my main camera soon after, so I no longer have a chance to use it, and I'm putting it up for sale. It works with Nikon cameras. To use it, attach this flash transmitter to the Nikon digital camera body, and you can wirelessly trigger a flash located at a distance at the same time as the shutter. *Requires a Yongnuo YN series strobe + a wireless remote trigger like the RF603. I've used both camera manufacturer strobes and other companies' strobes around Yongnuo, but Yongnuo is the simplest and easiest to use. I still use a transmitter for my Canon camera, which I repurchased. It makes taking pictures of food and objects fun. I got off track. I will ship it in bubble wrap. No smokers or pets. I will ship it the same day.
