Popphoto has an interesting article about US military photographers. The picture above is of a Nikon D700 with a Nightstalker II night vision system by Tactical Solutions LLC:
"Other lessons involve proper techniques for using cameras in conjunction with night-vision gear. Simple but potentially serious errors include failing to turn off the camera’s autofocus-assist lamp, which can overwhelm night-vision users with brightness and reveal the unit’s position to the enemy. Cameras with night-vision lenses lack AF systems—they focus manually. And setting exposure for night-vision cameras can be tricky."
Update: some images taken with this (and other similar equipment) can be seen at www.dlyost.com.
