    Does such a thing exist?? I spend a lot of time chasing owls at night, and trying to either manual focus (and cross my fingers) or paint with a flashlight/ shoot one handed/ not flush the bird etc. is a pretty lousy way of doing things. Is there any sort of aftermarket AF assist that will work when the shutter button is 1/2 depressed, or am I wishing for something that's not out there?

    I assume you are aware of the red AF-Assist light in the speedlights. Manuals say it is effective to about 33 feet. Seems to work in pitch black dark. I know of nothing else.

    Yeah, I'm using an SB-800 when I shoot them, but the built in AF assist usually isn't quite robust enough... sounds like I'm looking for something that doesn't exist??

    I am not aware of anything else. You could carry a big flashlight I guess. :smile:

    Laser pointer?
     
  6. I think a flash light is going to be likely the best option, as Wayne says speedlights have a red af assist beam that can work as well, duct tape a flash light to the camera / lens / something, one which allows you to focus the beam is my guess

    Just to be totally clear. Do you mean that the SB800's AF assist isn't powerful enough? (It is a lot more powerful than the built-in one, i.e. the one in the camera body.)

    I have used the SB800 AF Assist over long distances outdoors in total darkness, it works pretty well.

    Over what distance are you finding it a problem?

    I can also recommend a powerful head torch. That way you can aim the torch with your head while looking through the viewfinder. Some modern headtorches are as powerful as a car headlight, although those ones are quite expensive.
