The Benro's ArcaSmart 360 Dual Plate is an innovative quick release plate that features multi-angle functionality and a uniquely designed phone holder that allows you to adjust your camera or phone to a variety of positions that are perfect for your shot. Compatible with mobile devices as well as DSLR and mirrorless cameras, this meticulously designed plate lets you switch from landscape to portrait orientation by simply unlocking the knob and rotating. This head also provides a full 360? panning range to any tripod or monopod that it's attached to, which is made even more convenient by the 3/8"-16 threads in the base.
