e1 Flash Sync Speed
Explanation: The flash synchronization speed is the shortest possible exposure time that you can use with flash und you can choose here between 1/60 and 1/250 s which is the default.
The options 1/250 s (Auto FP) and 1/320 (Auto FP) mean:
- With an additional external flash that supports FP high speed sync (from Nikon all except the smallest SB-400) it will be activated to enable shorter exposure times.
In this case the flash will fire a series of flashes immediately after each other as long as the shutter is open. It will actually more behave like a lamp over the whole exposure time rather than a flash. This allows usage of shorter exposure times, with no limitation down to the very shortest that the D7000 can do.
The disadvantage of this feature is that the flash range goes down.
- With all other flashes that do not support FP high speed sync the D7000 will use 1/250 or 1/320 s.
Tips: Leave the default of 1/250 second. Short sync times are important when you use flash in daylight as fill flash.
