Blackmagic Design Spares - Camera PCC6KPro - Glass Filter

The Blackmagic Design Spares - Pocket Cinema Camera 6K Pro (PCC6KPro) - Glass Filter refers to the IR Cut / Optical Low Pass Filter (OLPF) that sits directly in front of the 6K Pro sensor.

In the 6K Pro, this glass is particularly vital because it must work in perfect harmony with the internal motorized ND filter system. It acts as the final "shield" for the expensive 6K sensor.

The Guardian of the Sensor

This isn't just a plain piece of glass; it is a precision-coated optical element:

• Infrared (IR) Filtration: Digital sensors are highly sensitive to infrared light, which can cause "magenta tinting" in dark areas of the image. This glass filters out those wavelengths to keep colors natural.

• Low Pass Filtering: It helps reduce "moiré" (strange patterns) and aliasing when shooting fine textures like fabrics or distant buildings.

• Dust Shield: It provides the physical barrier that prevents dust from landing directly on the silicon sensor. If you "clean your sensor," you are actually cleaning this glass.

When to Replace the Glass Filter

Because this glass is exposed every time you change a lens, it is susceptible to damage:

• Deep Scratches: If a lens rear element or a cleaning tool scratches the glass, the mark will appear as a soft, permanent blur in every shot, especially at high f-stops (like f/11 or f/22).

• Pitting/Corrosion: In humid or salty environments, the specialized coatings on the glass can sometimes "delaminate" or develop tiny pits that look like permanent dust.

• Cracking: A sudden temperature shock or a physical impact during a lens change can crack the filter.

• Staining: If improper cleaning fluids are used, they can strip the anti-reflective coatings, leaving "rainbow" streaks that ruin the image contrast.

Key Features

• Genuine OEM Part: Essential for maintaining the specific "Generation 5 Color Science" that Blackmagic designed for the 6K Pro.

• Precision Coating: Features an anti-reflective (AR) coating to prevent "ghosting" when shooting into bright light sources.

• Exact Fit: Sized specifically to fit the 6K Pro sensor housing, ensuring an airtight seal when combined with the internal rubber gasket.

Technical Installation Note

DANGER: Level 4 (Expert) Repair. Replacing the glass filter is an "open heart surgery" procedure for your camera.

1. The Dust Paradox: You are replacing a filter to get a clean image, but the act of opening the sensor chamber introduces new dust. This must be done in a localized "clean box" or a room with a high-quality HEPA air purifier running for at least an hour.

2. Gasket Integrity: The glass is held in place by a thin rubber gasket. If this gasket is pinched or misaligned during installation, dust will eventually leak behind the glass and land on the actual sensor, which is almost impossible to clean.

3. No-Touch Zone: Never touch the underside of the new glass. Once it is installed, you can only clean the top side.

4. Vacuum, Don't Blow: Use a specialized sensor vacuum or a hand-powered air bulb. Never use "canned air," as it can spray liquid propellant onto the new glass, permanently ruining the coatings.

Expert Advice: Before buying a replacement, try a professional sensor cleaning kit (swabs and specialized fluid). Many "scratches" are actually just stubborn streaks of oil or adhesive residue that a standard dry blow won't remove. If a wet clean doesn't fix it, then it's time for a hardware swap.

Are you seeing a permanent mark on your footage, or has the glass physically cracked?
