Designed for a precision fit on the Sony a7 III, a7R III, and a9 mirrorless cameras, this SmallRig L-Bracket 2122D is constructed from rugged aluminum and adds an Arca-type dovetail groove on both the horizontal and vertical axis, allowing orientation to change rapidly from landscape to portrait. Each axis features an index point for quickly centering the bracket on a tripod head. The adjustable side plate can be positioned to allow increased access for cables and movement of the display screen. The bracket features a 1/4-20 tripod socket on the base, plus four additional accessory sockets on the vertical segment for customizing the L-bracket for individual applications. The base also features a pivoting plate for accessing the battery door, which incorporates a contoured, rubberized pinky grip for added handheld stability. An anti-twist lip prevents the camera body from rotating out of position, and there are magnetic storage pockets for the included hex wrench and flat screwdriver, so that they are always on hand.
