I have a D2x and an SB-800. I would like to keep the flash position constant while I turn the camera from landscape to portrait positions. Could someone recommend a bracket (or other solution) to do this?
If you go with Really Right Stuff, you can buy their L plate which is specific to your camera model. I've never used the L plate from B&H that you provided the link for because I only use Really Right Stuff. As Luke said, it's an investment, but I believe it's a one time investment.
