Blackmagic Design Spares - Camera - Glass Filter EFThe Blackmagic Design Spares Camera Glass Filter EF refers to the IR Cut OLPF (Optical Low Pass Filter) assembly specifically for the Canon EF mount versions of Blackmagic cameras. This part is most commonly sought for the Pocket Cinema Camera 6K (Original & G2), the 6K Pro, and the URSA Mini Pro series.

The Blackmagic Design Spares - Camera - Glass Filter EF refers to the IR-Cut / OLPF (Optical Low Pass Filter) assembly specifically for the Canon EF-mount versions of Blackmagic cameras. This part is most commonly sought for the Pocket Cinema Camera 6K (Original & G2), the 6K Pro, and the URSA Mini/Pro series.

Because the EF mount has a larger throat and a longer flange distance ($44\text{mm}$) than MFT, this glass is larger and sits deeper within the "turret" of the camera body.


Core Responsibilities

  • Infrared (IR) Suppression: Blocks the infrared spectrum to prevent "IR contamination" (where dark fabrics or shadows take on a reddish or magenta tint).

  • Moiré & Aliasing Reduction: On models equipped with an OLPF (like the newer 6K Pro/G2 and 12K OLPF), this glass microscopically blurs fine repeating patterns that the high-resolution sensor would otherwise "alias."

  • Environmental Seal: Protects the sensitive CMOS sensor from dust, humidity, and accidental contact during lens changes.

When to Replace the EF Glass Filter

  • The "Cloudy" Sensor: Over time, humidity can react with the coatings on the filter, creating a permanent haze or "fungus-like" appearance. This is a common issue in humid climates and cannot be wiped away.

  • Surface Pitting: High-velocity dust (common in desert or wind-blown shoots) can create microscopic pits in the glass that cause "flaring" when shooting toward light sources.

  • Oxidation/Discoloration: If your images show a consistent color cast that cannot be corrected in DaVinci Resolve, the filter's chemical coating may have oxidized.

  • Cleaning Damage: Scratches from using improper cleaning tools (like a dry T-shirt or low-grade swabs) are the #1 cause for replacement.


Technical Installation Note

Repair Level: 2 (Moderate). While you are working inside the lens mount, you do not typically need to disassemble the entire camera chassis.

  1. The Turret System: In the Pocket 6K Pro and 6K G2, the glass is housed in a removable "turret." You remove three Phillips screws inside the mount to lift the entire glass housing out.

  2. Cleanliness is Mandatory: This is a "clean-room" operation. Any dust trapped between the filter and the sensor will be visible in your footage. Use a vacuum or a high-quality air blower (like a Giotto’s Rocket Blower) before and during installation.

  3. Gasket Integrity: Ensure the small rubber O-ring or gasket is seated perfectly. If the gasket is pinched, the glass will sit at an angle, causing one side of your image to be soft (out of focus).

  4. Flange Calibration (Shimming): Different thicknesses of glass change the optical path. If you switch from an IR-cut to an OLPF (or vice-versa), you may need to add or remove metal shims behind the EF mount to ensure your lens "Infinity" marks remain accurate.


Comparison: Filter vs. Sensor

Part Cost Complexity Symptom
Glass Filter $~100$ USD Low-Medium Scratches, Haze, IR Polluted Blacks
CMOS Sensor $~800+$ USD High (Expert) Dead Pixels, Vertical Lines, Pink/Green Tearing

Pro-Tip: The "Breath Test"

If you see a mark on the glass, do not immediately try to scrub it. Use a specialized sensor loupe (magnifying glass with LEDs) to determine if it is on top of the glass or etched into the coating. If a gentle wet-clean with a $24\text{mm}$ sensor swab and specialized fluid doesn't move the mark, the coating is likely damaged and the glass must be replaced.

Are you seeing a physical scratch on the glass, or is your image looking "hazy" and "soft" across the entire frame?

Healing & Understanding
Format: Paperback
We are living in a slave master's land (was the Indians..). Hundreds of years of slavery, mental torture and degradation and then "freed." No therapy. No understanding, not even patience. To listen to Dr DeGruy's youtube videos was so enlightening to me. Sorrow, but understanding and then JOY. I didn't understand the anger, towards myself or others. Now, I can see where so much pain has come from. I can show compassion and love towards myself and others. Whatever programming I had, has been deleted--destroyed. I look back with pride, hurt, and know that I, myself, can heal. What a blessing this woman has brought us! Thank you Dr. Joy DeGruy!

Why do black people . . .
Format: Hardcover
I purchased this book because I had many questions I wanted answered. Most of them were questions of "Why?". My biggest question was why we as black people have so many unhealthy habits in how we treat each other. As a young African American male who was raised by his mother in a predominantly white suburban area, I wanted to know why, when I encountered other black youth in more urban areas, they would tell me I "talk white." What is "talking white?" Basically, talking white means I was talking like I have an education. Why do so many members of the black community (those without an education) reject me for valuing education? Why is it that when one black person fidns a way out of the ghetto, it seems the whole neighborhood, church included, condems that person for leaving "his/her people" and wanting to live in the suburbs with the whites? Why don't we support one-another in this society that has always held us from achieving our full potential? I wanted to learn why we seem to have no clue of who we are, and so many of us, young and old, strive to "prove" we are "black enough." So talking a certain way makes us black? Or is it eating certain foods that makes us "black"? Listening to only certain kinds of music? We lack a firm sense of cultural identity. We take rebellious pride in being at the bottom, and equate success with "whiteness." We denounce the achievements of any black person and ostracize him from the community. We work to pressure our own to stay at the bottom. In this very interesting book, the author, Dr. Joy Degruy Leary, proposes a number of explanations for why the African American community has developed these and other unhealthy cultural habits. Leary examines this very real "crabs in the barrel" mentality, as well as many other self-destructive habits which plague the black community. Leary establishes a diagnoses, and calls it Post-Traumatic Slave Syndrome. Leary presents a very strong argument that the behaviors are all symptoms that have been passed down through the generations of African American people from the dawn of the trans-atlantic slave trade to today. Leary uses her own observations to support her theory of Post-Traumatic Slave Syndrome. This book is a very thoughtful read. The reason I give this work only four stars is because I truly feel that Leary's argument would have been much more affirmed and effective if she had included a visual timeline to help the reader to better understand the timeframes and chain of events in history discussed in the book. The argument also would have been more effective if the author spent more time on each point. At times it seems she's just getting started before summarizing all that was just said and moving on. Scholarly sources are cited and research is used, but the book does not explore any one study or statistic in great depth. It is a fast read.

America's Biggest Lie
African Americans have been brutalized beyond imagination. Then told that they were the ones that were less than human. It boggles the mind. The whites beat, burned, skinned, lynched, mutilated and murdered African Americans at will. And these same whites believe (to this day) that this is their god given right. Even worst was the emotional and intellectual scars left from the lies that were told. If I didn't see the consequence of this everyday, I would think someone was lying to me: Some kind of Cosmic joke. The white criminals are the heroes and the African victims are the villains. This cannot actually be real. But it is. Whites stripped the Africans of their names, religions, dignity, culture and their humanity. Then called them less than human. This slight of hand is beyond comprehension. The funniest part is when I hear Whites yell to blacks "go back to Africa." This is tantamount to kidnapping someone, tying them up, putting them in your basement then yelling at them to get out of your house. Insane. This has been going on for 400 years. Wow. And America thinks it the moral leader of the free world. I have to pinch myself. This has to be a dream.... or a nightmare. The book opened my eyes.

I have to step up as a parent..
Format: Hardcover
The book is a little bigger than what I realized. I must not have paid a attention to that because I did a quick buy. But thats not a bad thing it is a really nice coffee table book the pictures are great. I skimmed the book and it has some wonderful information. I wanted to have something to catch the attention of my GenAlpha son so he can learn about our history the school did a horrible job this year with learning Black history which is American history. Plan to get the study guide to help me talk about this with my son. Given the time we are living in I need to do better with informing and guiding him with facts. Because of my school and parents I learned a some of this growing up but the schools are barely teaching anything past MLK, Malcolm X or Harriet Tubman!
