    So I was showing my coworker some pictures of the mew puppah and he told me that his 1D and 5Dm2 has settings that the camera will take a picture when the subject comes into focus.

    Sooo can the Nikon D700 do this? What is this setting called?

    (Basically you manually focus the lens to a scene and when the focus point comes into focus shutter fires).

    my flash doesn't have enough power to expose the shot at F32

    And my lens doesn't go that small.

    it's called trap focusing.

    Nikon doesn't have a setting, but here's how you do it:


    1. Set custom setting #A5 to AF-ON ONLY

    2. Set the focus mode to SINGLE SERVO

    3. Set Auto focus area mode to SINGLE POINT (9 point, 21 point, 51 point or 51 point 3-D will all work)

    4. If your lens has an A/M switch, make sure it is set to A for autofocus mode.

    5. Pre-focus the lens for a particular distance. Don't forget that a more convenient way to use this trick is to pre-focus using not the shutter button, but the FOCUS button on the back of the camera can be used. I find this easier and more effective.

    6. Press and hold the shutter release ALL the way down, the camera shoots only when the selected focus bracket is in focus.


    (stolen from a random google search...)
