“The ultimate upgrade for your Blackmagic Pocket Cinema Camera, Blackmagic Micro Cinema Camera and Blackmagic Cinema Camera 2.5K (MFT)….

… Due to their size and image quality the BMPCC and BMMCC are widely recognized as great digital cinema camera’s [sic]. It’s now possible to get the most out of them by taking away their main weaknesses: moiré and IR contamination.

The RAWLITE IR-cut OLPF incorporates low pass layers that control the prevention of moiré. The original glass of the BMPCC and BMMCC does not have such layers….”

Blackmagic Pocket Cinema Camera 4K by Blackmagic Design, which apparently will need third party infrared-cut aka IR-cut filtration or the IR-cut OPLF solution provided by RAWLITE.

Commentary

When cinematographer John Brawley mentioned that he was investigating an IR-cut solution made by RAWLITE on the Blackmagic Pocket Cinema Camera 4K forum at EOSHD, I made a mental note to research the problem of infrared pollution in Blackmagic Design’s cameras and possible solutions.

I talked to a rep about the olpf at NAB and they said that they tend to not put filters on their cameras and if they do its always minor because they are obsessed with image quality. Kind of a shame in terms of IR pollution. I remember having to put my Hoya IR cut filter on every freaking lens I owned because the original pocket had such bad IR pollution. I think this cam will have the same issue. … David Altizer

Given that users of the coming Blackmagic Pocket Cinema Camera 4K will need to use fixed or variable neutral density filters on lenses attached to the camera, as it does not have built-in NDs like its URSA stablemates, it would be great if all NDs came with IR-cut capability, but they do not.

As a self-funded documentary moviemaker working fast and alone on location, variable neutral density filters are a more viable option than fixed value NDs and the last thing I want to do is add yet another layer of glass and filtration on top of my VNDs as Mr Altizer describes above.

Accordingly RAWLITE’s solution may be the bee’s knees provided it produces a version for the  Blackmagic Pocket Cinema Camera 4K in time for the camera’s projected release in September 2018.

Time will tell.
