Bright Tangerine 82 to 114mm Threaded Adapter Ring for Clamp-On Matte Box

This 82 to 114mm Threaded Adapter Ring for Clamp-On Matte Box from Bright Tangerine is essentially a step-up ring that allows you to mount a clamp-on type matte box to your lens with a filter thread diameter of 82mm. However, this adapter features a rear projecting 114mm ring, as opposed to most other step-up rings that project forward. The value of this adapter is that it allows you to mount your clamp-on matte box closer to the front of your lens, reducing the possibility of vignetting with wide lenses. However, the design of the adapter precludes using it to mount filters on your lens. The adapter features a step cut that allows you to use it with the Bright Tangerine Black Hole adapter for rod-mounted matte boxes with a 143 mm rear opening. Please note the Black Hole adapter and matte box are not included with this item. For use with lenses with a non-rotating front Mounts on lenses with 82mm filter thread 114mm diameter clamping surface projects towards the camera, allowing your clamp-on matte box to be closer to your lens for maximum image clearance Made from anodized aluminum Use with optional Bright Tangerine Black Hole adapter for use with matte boxes with a 143mm rear opening
