thanks for the advice guys! so Don, i could get my hands on a laser or something of that sort, but how would i actually connect it to the camera to turn on when the camera attempts to focus? is that possible at all? it must be somehow possible if external flashes have the ability, it may just be very very complicated. What do you think?

hello, i'm new to this flash business, and i'm not really here to discuss flashes, what i'm really interested in is a laser autofocus assist. Is there some kind of unit out there that will sit in tthe camera's hot shoe and simply shot a laser for the camera to focus on? i'm not looking for anything expensive, just something simple. If there is not something like this at all, it would be interesting to find out how the camera communicates with the external flash, so that perhaps, a simple autofocus assist could be built. (simple as in simple to use, nowhere near simple to build) Thanks for any info you can help me out with.
