Five point three millimetres, and it says why

K&F CONCEPT 67 mm CPL, 18 layers, 5.3 mm frame

Eighteen coating layers in a published 5.3 mm frame — the thinner of the two polariser frames on this shelf, for 18 €.

K&F Concept 67 mm circular polariser held against a bright sky

K&F CONCEPT 67 mm CPL, 18 layers, 5.3 mm frame

Eighteen coating layers in a published 5.3 mm frame — the thinner of the two polariser frames on this shelf, for 18 €.

Thread size
67 mm, in the title, with the fifth bullet naming Canon, Nikon, Sony, Samsung and FUJIFILM lenses of that thread
Type
CIRCULAR — Zirkularer Polfilter — in the title and the third bullet. The hub above explains why that matters: a circular polariser leaves autofocus and metering intact on a modern body
Light loss stated
NOT STATED, as on all four polarisers here. Eighteen layers raise transmission; what the polarising element itself takes out is the figure the hub above asks for, and no page on this shelf gives it
Coating description
EIGHTEEN-fold coating on high-grade optical glass, in the third bullet, credited with reducing reflections and holding image quality in difficult light. The highest count on this shelf, matching the same maker’s UV filter
Frame thickness
PUBLISHED at 5.3 mm, in the fourth bullet, described as an ultra-slim aluminium frame that prevents vignetting even on wide-angle shots. It is the thinner of the two polariser frames published here — the 28 € NEEWER gives 5.9 mm — and the reason is stated rather than implied
Rotation mechanism
Not described. The frame thickness is published and how the ring turns is not

  • Five point three millimetres of frame, published with the reason: no vignetting on a wide lens
  • Eighteen coating layers, the highest count on this shelf
  • No light loss published

Best for: A wide-angle or standard zoom at 67 mm where the frame has to stay out of the corners of the picture.

On the listing

Six bullets. Reflection reduction, the CPL filter removing disturbing silver reflections from water surfaces, glass and non-metallic surfaces indoors and out, named for landscape, interior, travel and portrait work, with a note that new and old packaging ship at random; image improvement, making a sky more intensely blue and reducing glare, and raising quality in portraits by minimising unwanted reflections; high image quality from a circular polariser in high-grade optical glass with an eighteen-fold coating, reducing reflections and holding quality in difficult light; an ultra-thin filter frame, the aluminium mount only 5.3 mm slim, preventing vignetting even on wide-angle shots; compatibility and ease of use, fitting all lenses with a 67 mm thread from Canon, Nikon, Sony, Samsung and FUJIFILM; and a closing bullet stating the brand is the world’s number one in lens-filter online sales volume among camera-accessory-focused brands, sourced to Euromonitor 2024 data.

Five point three millimetres, and the reason attached

A polariser is two rings, because it turns. That puts it further forward than a UV filter, and on a wide lens the corners start to see it. This page publishes the number and names the consequence.

Eighteen layers, on a filter that removes light on purpose

Coatings raise what gets through; the polarising element takes out what it must. The first number is published here and the second is not.

Non-metallic surfaces, which is the honest limit

Water, glass, leaves, paint. Polarisation barely touches the glare off bare metal, and the first bullet says “non-metallic” rather than pretending otherwise.

What the fourth bullet buys over the cheaper filter

The 16 € PROfezzion on this shelf publishes no frame figure at all. Five point three millimetres is what 18 € buys over 16 €, and the whole wide-angle question.

A sales rank, in a specification slot

Euromonitor 2024, cited properly, about the market and not the glass. A stop figure would have said more.

More polarising filters

  • NiSi True Color CPL filter with its knurled frame and blackened glass edge

    NiSi True Color CPL, 77 mm, 20 layers, Cine Sealed

    A hundred and two euros for a polariser whose coating is sold on colour neutrality and whose glass edges are blackened and sealed against condensation.

    Thread size
    77 mm, in the title — the largest on this shelf, and the size the buying advice above says to standardise on, since a step ring brings it down to everything smaller
    Type
    CIRCULAR, in the title. The hub above puts circular versus linear first for a reason: only the circular kind leaves autofocus and metering working
    Light loss stated
    NOT STATED in stops. The first bullet claims 99.9 per cent of light reflections eliminated — the same figure the 28 € NEEWER here publishes — and the exposure penalty a polariser imposes is absent from all four pages on this shelf
    Coating description
    TWENTY layers, in the third bullet, including an ULTRA-LOW-REFLECTION layer specified at 0.2 PER CENT, with double-sided water- and oil-repellent coatings for easy cleaning and scratch resistance. Fewer layers than the thirty of the NEEWER; the difference on this page is what the coating is claimed to preserve rather than how many there are
    Frame thickness
    NOT PUBLISHED — the one number this page omits, at 102 €. The fifth bullet claims no vignetting even on wide-angle lenses and gives no millimetres, where the 18 € K&F publishes 5.3 mm and the 28 € NEEWER 5.9 mm. What IS named is a matt black interior coating in the second bullet, to absorb stray light inside the frame
    Rotation mechanism
    A KNURLED frame — gerändelter Rahmen — in the fifth bullet, described as giving grip for quick mounting and removal. That is about fitting rather than turning; the 28 € NEEWER here is the page that describes the rotation itself
    Amazon reference
    B09XQXPG3C (same reference on 6 Amazon marketplaces)
    EAN
    6972949374020
    • A coating sold on colour neutrality, with the yellow cast of other filters named as the problem
    • Cine Sealed blackened glass edges, credited with preventing condensation
    • No frame thickness published, at 102 €

    Best for: Work where the polariser must not tint the image — video graded across shots, or landscape work in mixed light — and where condensation on a cold morning is a real risk.

  • PROfezzion 58 mm circular polariser with its rotating ring and case

    PROfezzion 58 mm CPL, twelve layers

    Twelve coating layers on a 58 mm circular polariser for 16 € — from a page whose fourth bullet gives the thread as 52 mm and explains where to check it.

    Thread size
    58 mm in the title — AND 52 mm in the fourth bullet, which says the filter fits any lens with a 52 mm thread. The same bullet then explains, usefully, that the correct size is printed on the lens after a ⌀ symbol. The title and the part number PF-58CPL agree on 58; the bullet is the odd one out, and the ⌀ on the lens settles it
    Type
    CIRCULAR, in the title and throughout. The hub above treats circular versus linear as the first question: a circular polariser keeps autofocus and metering working on a modern camera, and a linear one does not
    Light loss stated
    NOT STATED. A polariser costs light — commonly one and a half to two stops — and no page on this shelf publishes the figure. The hub above asks for it in stops, and four filters here leave it out
    Coating description
    TWELVE layers, multi-coated, in the third bullet, credited with reducing reflection and named for outdoor and landscape work over water, sky and plants. The same count as the maker’s UV filter on this site
    Frame thickness
    Not published — where the same maker publishes 3 mm on its UV filter. On a polariser the frame is necessarily thicker, because it has to rotate, and that makes the missing figure more significant rather than less
    Rotation mechanism
    Not described. A polariser is used by turning it, and how the ring turns — knurled, geared, stiff, smooth — is the whole ergonomics of the thing. The 28 € NEEWER on this shelf describes straight knurling and smooth rotation; this page is silent

    EAN
    6940202350500
    • Twelve multi-coating layers, on named Japanese glass in an aviation-aluminium frame
    • A bullet that explains where the thread size is printed, after the ⌀ symbol
    • The title says 58 mm and the fourth bullet says 52 mm

    Best for: A 58 mm lens used over water and foliage, where twelve coating layers for 16 € matter more than a published stop figure.

  • NEEWER 67 mm CPL filter showing its knurled rotating ring and case

    NEEWER 67 mm CPL, 99.9 per cent, 30 layers, 5.9 mm

    Thirty coating layers, reflection under 0.1 per cent and a published 5.9 mm magnalium frame — the only polariser here that describes how its ring turns.

    Thread size
    67 mm, in the title and the fifth bullet, supplied with a protective case and a cleaning cloth
    Type
    CIRCULAR, in the title, built on what the first bullet calls an imported polarising film. Circular is what keeps autofocus and metering intact, as the hub above explains
    Light loss stated
    NOT STATED — no figure in stops, as on all four polarisers here. What this page does publish is the other side of the transaction: 99.9 per cent of reflections from non-metallic surfaces eliminated, and a minimum light reflection of under 0.1 per cent off the filter’s own surfaces. Both are real numbers; neither is the exposure penalty the hub above asks for
    Coating description
    THIRTY LAYERS of polarising film on both sides of the filter, in the second and third bullets — the highest count on this shelf — with four properties named: water-repellent, oil-repellent, antistatic and scratch-resistant. The same bullet claims ultraviolet blocking from 300 to 380 nm, which is a stated waveband rather than a vague claim
    Frame thickness
    PUBLISHED, and in two parts: an ultra-thin 5.9 mm frame in MAGNALIUM ALLOY, plus a 3.8 mm front bezel that the fourth bullet says effectively prevents vignetting on wide-angle lenses. The 18 € K&F here is thinner overall at 5.3 mm; this is the only page that separates the frame from the bezel
    Rotation mechanism
    DESCRIBED — alone on this shelf. The fourth bullet gives black anodised threads with precision machining for effortless installation, and straight wheels for smooth rotation. A polariser is operated by turning it, and this is the one page that treats the turning as a specification
    Amazon reference
    B09HGHKN2R (same reference on 6 Amazon marketplaces)
    EAN
    0191073121478
    • Thirty coating layers, with reflection under 0.1 per cent and a stated 300-380 nm UV band
    • The only description of a rotation mechanism on this shelf
    • No light loss in stops, as everywhere on this shelf

    Best for: A 67 mm lens whose polariser gets turned constantly — landscapes, water, glass — where a smooth ring and a wipeable coating earn the extra 10 €.

Elsewhere in the camera bag

  • Pair of Rollei QAL-50 quick release plates in black aluminium with their fixing screws

    Rollei QAL-50, 49 by 41 by 10 mm, 45 g, two-pack

    Two Arca-compatible plates for 14 €, each 49 by 41 by 10 mm and 45 g — the only page on this shelf to publish all three dimensions and a weight.

    Profile
    Arca Swiss compatible, named in the title. The hub above is careful about what that means: the dovetail associated with Arca is cut by many makers to broadly compatible dimensions and published as a standard by none of them, so two plates of the same nominal type can sit differently in the same clamp. Naming it is still what makes a plate interoperable, and only two pages on this shelf do
    Length
    49 mm, with the full block published in the third bullet: 49 by 41 by 10 mm. Short, which is what it is — this is a plate for a camera base, not a long rail for balancing a telephoto
    Screw type and drive
    A 1/4 inch tripod thread, in the second bullet, and the drive is never named. The buying advice for this shelf is to take a plate with a folding D-ring, because a coin-slot plate needs a coin at the moment one is never to hand — and this page does not say which it is
    Anti-twist provision
    Not described. No lip, no rubber pad and no body-specific shaping appears, so what stops the plate rotating under a long lens is unstated. On a 49 mm plate with a single screw, that is the question
    Stated clamp compatibility
    All cameras with a 1/4 inch tripod thread, in the second bullet, plus the Arca compatibility in the title. Two statements covering both halves: what it screws into, and what it slides into
    Material
    Aluminium, in the third bullet, alongside the dimensions and the weight
    Published weight
    45 g each, in the third bullet. It is the lightest figure on this shelf, and the fourth bullet confirms two plates are supplied
    Amazon reference
    B008AH6X3I (same reference on 6 Amazon marketplaces)
    EAN
    4048805208685
    • Two plates for 14 €, so a second body is covered by the same purchase
    • All three dimensions and the weight published — 49 by 41 by 10 mm at 45 g
    • The screw drive is never named, so whether it needs a coin or a D-ring is unknown

    Best for: A second and third plate for cameras that stay on Arca clamps, where the price per plate matters more than the fittings.

  • SIRUI QC-55 quick release plate and its clamp base with a bubble level

    SIRUI QC-55, 55 mm Arca plate, 15 kg, with a base

    A 55 mm Arca plate sold with its own clamp base for 29 €, declaring 15 kg, with a bubble level and a rubber mat — the only kit on this shelf rather than a plate alone.

    Profile
    Arca compatible, in the title, with a 55 mm plate. It is the longest plate on this shelf — 6 mm more than the Rollei — and length is what lets a balance point travel, which the hub above says matters for a telephoto and not at all for a compact
    Length
    55 mm, in the title and the second bullet. The second also describes what the length is for in practice: the camera is pressed gently down from above rather than aligned and slid, so a longer plate gives more tolerance in where it lands
    Screw type and drive
    1/4 inch and 3/8 inch interfaces, in the first bullet — but on the BASE rather than the plate, which is what lets the clamp screw onto a tripod, a stabiliser, a gimbal or a video monitor. The drive on the plate screw itself is not named
    Anti-twist provision
    A protective rubber mat, in the third bullet, named for guarding equipment against scratches. It is the same part that resists rotation under load, and the page describes its protective role rather than its grip
    Stated clamp compatibility
    Its own, and that is the point: this is a kit. The first bullet names tripods, stabilisers, gimbals and video monitors as what the base screws onto, and the 1/4 inch interface as covering most camera models. Buying the clamp with the plate removes the question the other three pages leave open
    Material
    High-grade aluminium, in the fourth bullet, with a claimed capacity of up to 15 kg while remaining light
    Published weight
    Not published. The fourth bullet calls it featherlight and gives no figure — the one omission on an otherwise complete page
    Amazon reference
    B0DB5RWZTL (same reference on 6 Amazon marketplaces)
    EAN
    6952060074443
    • The plate and its clamp base sold together, so compatibility is settled in the box
    • Fifteen kilograms declared, and a 55 mm plate — the longest here
    • No published weight, on a page that calls the kit featherlight

    Best for: Adding an Arca clamp to a tripod, gimbal or monitor arm that does not have one, with a plate matched to it from the start.

  • VRIG AC-12 magnetic quick release plate in two parts with its sliding lock

    VRIG AC-12, magnetic claw, 40 by 24.5 mm, 50 g

    A magnetic two-part quick release at 14 €, 50 g, with a stated limit no other plate here gives: 400 g, and the page says not to exceed it.

    Profile
    The maker’s own. The first bullet calls it a claw mini quick-release design originally developed by VRIG, and it is not the Arca dovetail — so nothing else in a bag will accept it. The hub above says a proprietary profile is unambiguous within one maker and useless outside it, and that is exactly the trade here
    Length
    40 mm, with the width in the fourth bullet: 40 by 24.5 mm. It is the smallest plate on this shelf, which suits the action cameras it is made for and rules out balancing anything longer
    Screw type and drive
    Two 1/4 inch threads — one in the base, one in the plate — named in the second bullet, and the drive is not published. What the same bullet does describe is the arrangement: the screw plate stays on the action camera, so remounting is a slide rather than a rethread
    Anti-twist provision
    A rubber pad, in the third bullet, described as anti-slip. On a 24.5 mm plate under a 100 g action camera that is adequate; the hub above notes that anti-twist matters most under a long lens, which this plate explicitly refuses to carry
    Stated clamp compatibility
    Its own base, and nothing else. The second bullet describes a two-part system joined by a sliding lock; the third says the 1/4 inch connector also suits a monopod or a monitor. So it interoperates by THREAD rather than by profile — which is a different kind of compatibility, and the honest reading of a proprietary claw
    Material
    ABS and aluminium, in the fifth bullet, described as robust and durable
    Published weight
    50 g, in the fourth bullet, with the dimensions. Five grams heavier than the Rollei pair for a two-part mechanism rather than a single plate
    Amazon reference
    B0DR2NBLB6 (same reference on 6 Amazon marketplaces)
    EAN
    6975150721058
    • A stated load limit of 400 g, with an explicit warning not to exceed it
    • Two parts, so the plate stays on the camera and remounting is a slide
    • A proprietary claw profile, so nothing else in a bag will accept it

    Best for: An action camera moved between a tripod, a grip and a selfie stick several times a day, where one second beats one thread.
