Quick Answer

Use the NiSi Single FS ND Cinema Filter Bag to safely store and transport one 4x5.65 cinema filter. Its slim, lightweight design fits into any camera bag or AC kit while providing dedicated protection.

Why a dedicated filter bag matters for cinema workflows

A loose filter in a camera bag invites scratches, dust, and fingerprints that can ruin a shot. The NiSi Single FS ND Cinema Filter Bag is purpose-built for professional cinema, holding exactly one 4x5.65 filter with quick flip-top access. Its slim profile slides into a matte box case or AC pouch without adding bulk, so you always have the right ND ready without digging through a cluttered case.

Trade-offs: single vs. multi-filter storage

Carrying one filter per bag means you need multiple pouches for a full ND set. The trade-off is that each filter gets its own protected compartment, preventing glass-on-glass contact and making swaps faster on set. If you prefer carrying several filters in one sleeve, consider a multi-pocket filter case instead.

How to Store Your Cinema Filter in the NiSi Single FS ND Bag

  1. 1. Clean the filter before storing: Use a blower or microfiber cloth to remove dust and smudges. A clean filter prevents particles from scratching the glass when sliding into the pouch. Skipping this step can embed grit into the fabric lining, causing micro-scratches over time.
  2. 2. Orient the filter correctly: Hold the filter by the edges and slide it into the bag with the coated side facing away from the pouch's flap closure. This reduces contact with the interior seam. Inserting the filter backwards can cause the coating to rub against the stitching, leading to wear.
  3. 3. Close the flip-top securely: Press the flap down until it clicks or aligns flush. Check that no part of the filter protrudes before placing the bag in your kit. A partially closed flap leaves the filter exposed to dust and accidental drops.
  4. 4. Place the bag in a padded compartment: Slide the pouch into a dedicated slot in your camera bag, matte box case, or AC kit. Avoid stacking heavy items on top of it. Even a padded pouch can't protect against crushing if it's wedged under a heavy lens or body.
  5. 5. Label the bag for quick identification: Use a permanent marker or label maker to write the filter type (e.g., "ND 0.9") on the outside of the pouch. This saves time when swapping filters on set. Without labeling, you'll have to open each bag to check, slowing down your workflow.
