Fotga Pro Glass Cine 4x5.65 ND16 4-Stop Neutral Density Filter

In this review the Fotga Pro Glass Cine 4x5.65 ND16 filter is examined as a practical tool for filmmakers and photographers who need reliable exposure control in bright conditions. The bottom line: this filter delivers predictable four-stop light reduction with minimal color cast, making it a useful addition for outdoor shoots where controlling shutter speed and aperture is crucial. The review focuses on real-world handling, optical quality, and durability to decide whether it belongs in a professional matte box kit.

Key Features

• Precise 4-stop reduction: The ND16 (ND1.2) rating reliably reduces light by four stops so users can use slower shutter speeds or wider apertures in bright sunlight.
• High quality optical glass: The environmental optical glass construction preserves image sharpness and contrast without introducing a noticeable color cast.
• Nano multi-coating: Double-sided nano coatings add scratch resistance and make the surface water, oil and fingerprint resistant for easier field maintenance.
• Matte box compatibility: The 4 x 5.65 in size fits standard 4x5.65 in filter trays used by many matte boxes, simplifying integration into a professional workflow.
• Solid build thickness: At 4 mm thickness the filter feels substantial in hand and resists flexing while mounted in a holder.
• Portable carry case: Includes a plastic carry case that protects the filter during transport and helps prevent accidental scratching when not in use.

Who It's For

The Fotga ND16 is aimed at independent filmmakers, videographers and photographers who shoot outdoors and need consistent exposure control to create motion blur or maintain shallow depth of field. It is particularly useful for shooters who use matte box systems and require sheet-style filters sized 4 x 5.65 in to fit existing trays.

Those who should look elsewhere include users who need variable ND control or photographers who only use screw-on round filters; this fixed-density sheet filter is not a substitute for a variable neutral density or for filter threads that don't accept matte box trays.

Pros & Cons

Pros

• Reliable four-stop light reduction allows controlled shutter speed and aperture choices in bright conditions.
• Optical glass construction maintains image clarity without an obvious color bias.
• Double-sided nano coatings resist scratches and repel water, oil and fingerprints for easier cleaning on set.
• Includes a protective plastic case for transport and storage.

Cons

• Fixed ND strength means you need multiple filters or a variable ND for situations requiring fine-grain control.
• Sheet format requires a matte box tray and is not usable on lenses without a compatible holder.

Our Verdict

The Fotga Pro Glass Cine 4x5.65 ND16 is a straightforward, well-built sheet neutral density filter that gives dependable four-stop exposure control with minimal color shift. It represents good value for filmmakers and photographers who use matte box systems and want a durable optical glass filter that resists scratches and fingerprints; however, those needing variable ND or screw-on convenience should consider other options.

Frequently Asked Questions

Will this fit my matte box?
Yes, the filter is sized for standard 4 x 5.65 in matte box trays but will not fit screw-in filter threads.

Does the filter add color cast?
The optical glass and coatings are designed to minimize color cast, and in normal use the filter preserves neutral color balance.

Is the surface easy to clean?
The double-sided nano coatings repel water, oil and fingerprints, making smudges easier to remove without risking scratches.
