Optical Low Pass Filter for Blackmagic URSA Mini Pro 12K

+ Moiré filtration + IR-cut
+ Easy Installation
+ Shim, tools and video for installation included

Aliasing and moiré are common issues with digital imaging. To prevent it from occurring most digital cinema camera’s (including the Arri Alexa) have a built in Optical Low Pass Filter (OLPF).

The original IR absorption filter of the Blackmagic URSA Mini Pro 12K does not have an OLPF.

Blackmagic made it easy to change the filter. The interchangeable mount can be easily removed. Behind the mount the original filter is held in place by three screws. After removing the filter the Rawlite OLPF can take it’s place.

This Rawlite OLPF is specifically designed for the Blackmagic URSA Mini Pro 12K, preventing moiré while preserving the high detail that this camera is able to capture with it’s 12K resolution. The assembly has been designed to preserve the same flange depth (distance between the rear of the lens and IR-filter). By doing so it’s assured that all mounts, lenses and adapters that work with the original filter, will work with the Rawlite OLPF.

A hot mirror coating is added to cut infrared light very effectively. An anti-reflective coating prevents unwanted reflections and enhances contrast. No more moiré, no more IR contamination. This means no need for expensive IRND.

The Rawlite OLPF is thicker than the original filter. Consequently a shim is needed to correct back focus. The shim is included in the kit, as well as tools needed for installation.
