This Atoll Extender Plate lets you mount DSLR cameras onto the Silence Corner Atoll S or C camera angle adjuster. The Atoll D for DSLR cameras includes the Extender plate as standard; if you have an Atoll S for Sony mirrorless or Atoll C for mirrorless cameras and need to mount it onto a camera with a longer flange distance, the Extender Plate can be swapped in for the standard plate to accommodate the extra depth. The Extender Plate is Arca-Swiss compatible as well as being compatible with Capture Clip accessories. It is made from a single piece of machined aluminum, and has a black finish.
