Dot Line Double Hot-Shoe Bubble Level for Sony

This Double Hot-Shoe Bubble Level for Sony from Dot Line has a crystal clear housing with two bubbles and mounts onto any Sony camera hot-shoe in either a horizontal or vertical position. It allows you to align the camera precisely on two planes, to keep the horizon line absolutely straight. This is necessary for QTVR shooting sessions, for landscapes, or any other photography requiring fidelity to a horizon line or other straight-line elements.
