The Sekonic L-208 TwinMate is a palm-sized device suitable for measuring incident and reflected light, which can be mounted on a hot shoe or a holder with the included adapter for quick, camera-positioned reference measurement. Although it is primarily designed for entry-level use, the more experienced can see it as an accurate, quick-to-place backup tool. Rangefinder camera owners looking for a tool to measure incident and reflected light may also appreciate the included hot shoe adapter.
