The A7s Kickstand Plate is an Arca-Swiss-compatible quick releaes L-Plate for Sony A7, A7r, and A7s cameras.
The base plate (landscape dovetail) extends the camera's grip 15mm (about half an inch) and is ergonomically tapered, reducing fatigue and discomfort. It allows unrestricted access to the battery compartment. A portrait dovetail, which allow easy access to the left-side I/O ports, is also included.
An optional "kickstand" is also available. The weight of LCD hoods/loupes such as the Zacuto Z-Finder pull the articulating LCD downward. The kickstand holds the LCD in place, freeing the photographer's hands. Tilting the LCD up 56 degrees, the kickstand allows the camera to be held below eye level. This reduces fatigue and allows the arms to more readily be braced against the torso for stability. Spring-loaded pins hold the kickstand in place so it can be attached and removed without tools and without taking the plate off your camera.
Unlike most camera/lens plates, the Kickstand Plate can rest on a flat surface because its safety stop pin retracts (spring-loaded).
The plate's "capturing" threads are recessed from the mating surface to minimize cross-threading.
