SB800 in low light

Discussion in 'General flash photography, lighting, and technique' started by ashman, Jul 20, 2008.

  1. I am new to the SB800 and used it recently in a low light situation, all I got was out of focus shots. I thought this flash had an infrared 'helper' on the front to aid focusing in low light, is it supposed to engage automatically or does it need to be turned on. I couldn't make heads or tales of the manual and find anything helpful on this.

    The most common reason for "failure" of the AF assist illuminator on the SB-800 is not setting the camera to single servo autofocus (AF-S). AF assist will not operate in continuous (AF-C) or manual focus modes. The distance and focal length ranges where AF assist is effective are described on pages 62 and 63 of the SB-800 manual. Also, have you checked that AF assist is not disabled in the custom settings menu as described on pages 67-70 of the manual?
