Hello Nikonians, I have 2 D700s that I use on my weddings. I have been having some issues that I would like to address hoping I can get answers. the issue happens at the reception at night time. Here is my setup: nikon D700, Pocket Wizard mini, and Nikon SB910, the lens is Nikon 24-70mm and last night I used my Sigma 50mm, and my 70-200mm when the issues started... Here is the issue...when I click on the shutter release button 1/2 way to focus and after the camera focuses and ready to take the picture , I click the shutter release button all the way down to take the picture but NOTHING happens, it wont take a picture, I do it multiple time but nothing happens. I turn the camera off along with the mini flex and the speed light, and turn them back on, but nothing happens. after several tries it works. it is so frustrating when you pose people and ready to take a picture by your camera fails to do so. this happens on my last 4 weddings, but it doesn't happen all the time. I am not sue if it's a camera issue, a pocket wizard issue or maybe a combined issue with pocket wizard and camera. HAS any one had similar issues like mine and if so what did you do to fix it. Last night I am certain it happened to both my camera. appreciate any feedback.
