Hi guys, can anyone with experience with the Nikon wireless flashes comment on how reliable the wireless is? I believe it's infrared and needs line of sight to work. How is the range, and do you run into situations where the infrared is limiting? Also, say for example I have my SB600 on a stand and aimed backwards into an unbrella, will it still be able to "see" the infrared signal? Currently I have a Nikon D40, SB600 flash and the Nikon cable which allows me to use this flash off camera. I'm thinking about adding an SB800 which I'll use on-camera (or with the cable) and use it to trigger the remote SB600 wirelessly. Or would I be better off getting a cheaper flash and some pocket wizards or some other solution? I'm a bit limied with the D40 (it has no wireless commander mode), so I'm not sure if a better body should be the priority. I see guys with D300's and pocket wizards, which makes me think upgrading the body won't solve all my problems!
