Hi folks, Would someone tell me, if I set my off camera SB910 to manual,using the D7100's flash as a commander, does the camera still control the flash power and other settings on the SB910? Or would I set the flash power and zoom settings on the flash? Thanks in advance. Mike
The camera will control the flash power in the menu, see page 247 of your manual. Zoom settings in auto mode zoom the flash wide when not on a camera. That makes sense, in that it give you greatest coverage and easier to use when setting up. That being said, you can place the flash in manual zoom and set it to your liking.

Thanks Scott, I am starting to use manual flash setting more. I am finding that once I get the setup right I can cosistantly get the skin tone and texture that I like to see. Thanks again for your response, Mike
So I set the camera up just now and did a little experimenting. I noticed that if I mount the SB910 directly on the D7100's hot shoe and use it as an on-camera flash (manual camera and manual flash), the flash is not controlled by the e3 Bracketing Flash menu. If I set the menu to 1/2 power and the SB910 is set to 1/8 power, it will expose the shot at 1/8 power. I went through some drastic changes, 1/1 to 1/128, just to verify this. Now, on the other hand, if I set the flash up off-camera and use the e3 menu to set up commander mode ( and set the flash to slave), the flash shoots at the power level set in the menu. If you set the menu at 1/4 the flash will shoot at 1/4, even if the flash had been set to a different level. This info is probably in the manual somewhere but I had never really noticed it until now. I had always just set the SB910 at the power I wanted to work at and left it there. All this just for general info. Thanks, Mike

This is because menu item e3 control for external speedlights works through signals sent by the built-in flash to the remote flash. Since the built-in flash is not deployed when you have a flash in the hotshoe, there can be no control from the built-in flash. At least, that is how I think it works...
The Flash Commander menu in the camera only applies when using the built-in Speedlight as Commander.
The SB-700, SB-800, SB-900, and SB-910 have their own Commander menu built into the Speedlight. When using a Speedlight in your cameras hotshoe you must use the menu in the Speedlight to adjust the flash mode and settings.
