The 8Sinn 15mm Baseplate is ARRI dovetail compatible and supports optional camera-specific riser plates from 8Sinn. Available plates include the Riser Plate Basic, which supports the URSA Mini, C100, and Sony FX-9 cameras, and the Riser Plate I, which is for select 8Sinn Z CAM, a7/a7R, and Blackmagic Pocket 4K/6K cages. These optional plates set the supported cameras at the appropriate optical center on the 15mm Baseplate.

The 15mm Baseplate features 15mm LWS rod support via front and rear rod ports and a tightening lever on the left and right sides. The left side has a second lever, and this is for securing the compatible riser plate. The 15mm Baseplate offers two ARRI rosette mounts for attaching optional handgrips, and it also provides a section with multiple 1/4"-20 accessory mounting threads. The baseplate is made with excess weight cut out to provide a minimalist, lightweight design.

The Riser Plate Basic from 8Sinn is designed to support select cameras when used with the optional 8Sinn 15mm Baseplate (8-15BP). It supports the Blackmagic URSA Mini, Canon EOS C100, and Sony FX-9 cameras, setting each camera at the optical center on the baseplate. It's made of aluminum and comes with 1/4"-20 and 3/8"-16 screws. Rubber padding provides better support for your camera.

The 8Sinn 5" ARRI Dovetail Plate can be used with 8Sinn's 15mm Baseplate or 3rd-party ARRI dovetail bridge plates. In comparison to the 10" version from 8Sinn, this shorter and thinner plate is more ideal for balancing smaller camera setups, as opposed to large setups with large lenses. The plate is designed with cutouts throughout its length so that it can be more lightweight. In this minimalist design made out of a single piece of aluminum, the plate offers reinforced 1/4"-20 and 3/8"-16 threads, a release pin, and a stopper screw.
