Master Series 100 mm Filter Kit

The Benro Master Series kit centres on a 100 mm wide filter holder that accepts square or rectangular filters up to 2 mm thick. It ships with adapter rings sized at 72, 77, 82, 86 and 95 mm so the holder fits a wide range of lens threads. The holder is precision machined from aluminium alloy with scratch-resistant rubber coatings and includes foam light baffles to block stray light between filters. A Master Series SHD CPL HD 82 mm circular polarising filter made from B270 German Schott glass is also supplied.

Patented rotating CPL mechanism

A patented design lets the circular polariser rotate independently without loosening or removing other filters already seated in the holder. Engraved scales on the holder allow precise angular positioning of the CPL for repeatable results. The multi-filter system accommodates the CPL plus up to two additional 100 mm filters at the same time, enabling combined polarisation, neutral density or graduated effects in a single setup.

Check lens thread and filter thickness

Verify that each lens you intend to use has a front thread matching one of the five supplied ring diameters. Confirm that any square or rectangular filters you already own measure exactly 100 mm wide and no more than 2 mm thick, otherwise they will not seat correctly. Ensure the 82 mm CPL thread matches the holder’s CPL slot; other CPL sizes are not compatible with this kit.

Questions about this item

How do the foam light baffles hold up after repeated filter changes?

The foam light baffles block stray light between filters; they are consumable and should be checked periodically for compression or tears that could let light leak.

What is the thickest filter stack the holder can accept before vignetting appears?

The holder accepts a circular polarizer plus two 100 mm filters up to 2 mm thick each; adding more glass increases vignetting risk especially at wide angles.

Does the aluminium alloy body get hot during long daylight shoots?

The precision-machined aluminium alloy body remains at ambient temperature during all-day use; it has no electronics so heat build-up is not a concern.
