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 €.
