Baseline 15mm LW (Pixboom Spark)

Baseline 15mm LW (Pixboom Spark) is a baseplate that holds 15mm lightweight rods at the correct distance from the center of the lens on the listed cameras. ARRI dovetail slot on the bottom attaches to the included Baseline ARRI Dovetail or other ARRI standard dovetails using a top-load locking mechanism. Loosen the thumbscrew and push the silver button on the operator's side to release the baseplate from the ARRI dovetail. To reattach, drop down and listen for the pop to know it has engaged. Adjust the position on the ARRI dovetail, then lock the ratcheting thumbscrew. Baseline ARRI Dovetail is the included lower ARRI mounting plate, which can attach to tripod plates using 1/4-20 or 3/8-16 screws or ARRI standard bridgeplates with centered or offset screw spacing. ARCA dovetail slot on top holds the included ARCA Dovetail and can be top-loaded or installed from the back by sliding in. When sliding in from the back, a safety pin will engage with a pop when properly installed. Adjust the position, then lock the ratcheting thumbscrew. Top-loading can be achieved by loosening the thumbscrew, pulling out on the ratcheting knob, and turning the thumbscrew until the ARCA clamp has opened fully. Reverse the process to tighten. Center screw slot on ARCA Dovetail accepts 1/4-20 and 3/8-16 mounting screws, and a vertical rod hole clamps included 1/4-20 lens support posts for adaptors like Metabones, etc. Product Weight: 11.78oz (334g) Product Dimensions (WxLxH): 4.84 x 5.51 x 1.30in (123 x 140 x 33mm)
