[Aki]’s Nikon D2H did not come with an autofocus assist light. His other cameras have them, and he likes the feature, so he decided to hack one into his D2H. He wired into the AF system, so that his LED gets voltage when the shutter release is pressed half way. The circuit needs refinement though, he found that the light was staying on during shutter release and affecting his light metering. You can see the hack in action after the break.
