#2. "RE: SB-700 TTL Selection Using Spot Metering?" In response to In response to 0 Thu 22-Nov-12 05:59 PM by mklass
The SB 700 woks differently that the other Nikon Speedlights, in that the use of TTL or TTL-BL is determined by the camera settings, you can't set it on the flash.
When your camera is set to spot meter and the SB-700 is in TTL, the camera will meter on the focus point and send that info to the flash. Should you need to meter on a different point that the focus point, you can set the AE-L/AF-L button to Flash Value Lock (Assign AE-L/AF-L in the Controls section of your Custom Setting Menu, but not sure what camera you are using as your profile isn't filled out). Press the button when focused on the spot you want to meter, then recompose to focus and shoot.
