Blackmagic Design Spares - Camera CC6K - OLPFThe Blackmagic Design Spares Camera CC6K OLPF refers to the Optical Low Pass Filter assembly. It is important to distinguish between the original Pocket 6K (G1) and the newer 6K G2 6K Pro 6K Full Frame, as Blackmagic changed the OLPF design significantly between these generations. In digital cinema, the OLPF is a specialized glass stack that sits in front of the sensor to reduce Moir (strange patterns on fine textures like fabrics) and Aliasing

The Blackmagic Design Spares - Camera CC6K - OLPF refers to the Optical Low Pass Filter assembly. It is important to distinguish between the original Pocket 6K (G1) and the newer 6K G2 / 6K Pro / 6K Full Frame, as Blackmagic changed the OLPF design significantly between these generations.

In digital cinema, the OLPF is a specialized glass stack that sits in front of the sensor to reduce Moiré (strange patterns on fine textures like fabrics) and Aliasing (jagged edges).


1. The Original Pocket 6K (G1)

The original 6K (G1) did not come with a built-in OLPF from the factory; it only had a standard IR-cut filter.

  • The "Spare" Part: Most users seeking an "OLPF" for the G1 are actually looking for the IR-cut filter replacement or a third-party modification kit (like Rawlite).

  • Replacement Need: You typically replace this if the original glass is scratched, oxidized (showing a "cloudy" or "magenta" tint), or if you want to upgrade the camera’s ability to handle fine patterns.

2. Pocket 6K G2 / 6K Pro / 6K Full Frame

These newer models were designed with a more modular "turret" system, making the filter assembly much easier to service or swap.

  • The Assembly: On these models, the OLPF/IR-cut stack is housed in a matte black cylinder (the turret) inside the EF or L-mount.

  • User-Serviceable: Blackmagic designed these to be replaced by loosening just three screws inside the mount. You do not need to open the camera chassis to access this part.


When to Replace the OLPF

  • IR Contamination: If your "blacks" are turning brown or reddish under sunlight or tungsten light, the IR-cut coating on the OLPF glass has failed.

  • Physical Scratches: Any mark on this glass will be visible in your footage, especially when stopping down the lens (e.g., $f/11$ or $f/22$).

  • Coating Delamination: In humid environments, the multi-layer coatings can "bubble" or peel, creating a hazy look in your images.

  • Moiré Issues: If you are shooting for broadcast or high-end commercial work where fine patterns are common, you may need to replace a damaged OLPF to maintain professional image standards.

Technical Installation (6K G2 / Pro / FF)

Repair Level: 2 (Moderate). 1. Turret Removal: Use a precision Phillips head screwdriver to remove the three screws inside the lens mount.

2. Extraction: Carefully lift the matte black turret out using plastic tweezers.

3. The Glass Swap: The OLPF/IR glass is held in place by another set of small screws or a retaining ring.

4. Flange Focus (Shimming): Critical Note. OLPF glass has a specific thickness that affects where the light hits the sensor. If you replace the glass with a different thickness (common with third-party OLPFs), you must add or remove shims behind the lens mount to ensure your lenses still hit "Infinity" focus correctly.


Identifying the Part You Need

Camera Model Filter Type Ease of Repair
Pocket 6K (Original) IR-Cut Only (No OLPF stock) Moderate (Requires tweezers)
Pocket 6K G2 / Pro Combined OLPF + IR-Cut Easy (Turret system)
Cinema Camera 6K (FF) Combined OLPF + IR-Cut Easy (Turret system)

Expert Advice: If you are seeing "dust spots" on your image, always try a professional sensor swap/wet clean first. What looks like a scratch on the glass is often just a streak of oil or a stubborn dust particle that a blower can't move. Only order the replacement if a wet clean fails to resolve the mark.

Are you looking to replace a damaged original filter, or are you trying to install an aftermarket OLPF to reduce moiré?

Cute but run big
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Flamingo Pink
Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option

Good choice
Size: Medium, Color: Flamingo Pink
Or for my daughter for Christmas she absolutely love. She said that they are very comfortable, to wear under clothing and working out. Material is racing and soft padding is just right. Also good for working out.

My new favorite sports bra
Size: Small, Color: Black
Best sports bra I’ve purchased on Amazon. I wear sports bras every day either while working or to work out. This one is my new favorite. I got a size small and am a 34B or a 36A. The fit is better than my Lululemon. It doesn’t dig in and the adjustable shoulder straps make it fit more or less snug.
