QR-HD1
Quick Release Baseplate
The Quick Release Baseplate makes camera mounting and
dismounting immediate and solid. The dedicated baseplate
rod holder has a unique centering system, adjustable both
vertically and horizontally. The rear clamp collar post is
adjustable from 1.5 mm to 2 mm, ensuring a solid
attachment. The QR-HD1 features a mechanically locked
camera base to bridgeplate attachment which can be
adjusted for a perfect fit via a knurled knob on the rear
of the unit. This system provides a more solid attachment
than the common spring-tensioned systems.
ULB-3
Universal Lightweight Bracket
The ULB-3, specifically designed for digital cinematography,
replaces the stock v-shoe attachment common on cameras
such as the Sony F900, Panasonic Varicam and HDX 900.*
A universal drill pattern allows direct mounting to the
camera body and new dial support post attachments
provide additional stability and reduce flex. This unit
incorporates a right side rosette for handgrip attachment
with optional left rosette for two handle operation.
As with the QR-HD1, the ULB-3 incorporates a centering
adjustment system to compensate for variations in camera
base to optical axis measurement.
