Overview

For photographers working with compact cameras, drones, or small-format video rigs that take a 37mm filter thread, the Neewer True Colors CPL offers a practical way to tame reflections on water, glass, and foliage without muddying your palette. It's the kind of filter you thread on for a golden-hour lakeside shoot and forget about — skies deepen, surface glare falls away, and the colors that come through look honest rather than artificially warm. Whether you're pulling richer blues out of a cloudscape or cutting the sheen off wet leaves after rain, the polarization effect dials in smoothly with a turn of the frame.

Build quality is solid for the price tier. The aluminum alloy frame feels secure without adding noticeable weight, and the knurled edge gives enough purchase to rotate precisely even when your hands are cold or gloved. The 30-layer nano coating on both glass surfaces earns its keep — fingerprints wipe away easily, and light mist or spray beads up rather than smearing across the element. The included case and cleaning cloth are welcome touches for tossing the filter in a bag between shoots. It's a no-fuss polarizer that handles the essentials reliably on smaller lens systems.

Key Features

【True to Life Color Reproduction】A true color CPL filter stands out for its ability to eliminate glare without casting a yellowish tone on images. It helps deliver true to life colors for landscape photography

【Enhanced Contrast & Reflection Free】The circular polarizing filter effectively reduces glare and reflection from water, glass, foliage and other nonmetallic surfaces. Rotate the CPL filter to get clear images with more details and increased saturation

【Multi Coated HD Optical Glass Build】The CPL filter is built with 30 layers of Nano coatings on both sides for solid protection against scratches, dust, fingerprint, water, and oil. The HD optical glass material helps capture vivid colors and manage contrast without losing image sharpness

【Lightweight Aluminum Frame】Firmly sealed with ultra slim aluminum alloy frame, the filter delivers your desired effect without causing dark corners or vignetting. The non slip pattern on the frame provides a firm grip and makes the filter easy to install and rotate to change polarization

【37mm Camera Lens Filter】The CPL is of 37mm thread size. Please double check the lens filter thread of your camera (marked with the "Φ37" symbol under lens barrel). Package includes a CPL filter, a lens cleaning wipe, and a filter case

Pros & Cons

👍 Pros

  • Maintains neutral color accuracy so landscape tones look true to life straight out of camera.
  • Thirty layers of nano coating on each side resist fingerprints and water spots during outdoor shoots.
  • Ultra-slim frame avoids vignetting, which matters on the compact lenses that typically use 37mm threads.
  • Knurled grip ring makes rotation adjustments easy even with cold fingers in the field.
  • Lightweight enough that it adds virtually no heft to small action cameras or compact setups.

👎 Cons

  • The 37mm thread size limits compatibility to a narrow range of compact, action, and drone lenses.
  • At full polarization the 1-2 stop light loss can push you to higher ISOs in dimmer conditions.
  • The slim frame profile leaves little room to stack additional filters without risking vignetting.
  • Budget-tier glass may not match the micro-contrast performance of premium polarizers on high-resolution sensors.

Frequently Asked Questions

No noticeable color shift. The True Colors design maintains neutral rendition, so skies and foliage come through without the yellowish warmth common in budget polarizers.
The ultra-slim aluminum frame is designed to avoid dark corners, even on wider focal lengths that use a 37mm thread. You should be clear of vignetting in normal shooting.
Expect roughly 1 to 2 stops of light loss depending on the rotation angle, which is typical for a CPL. You may need to bump ISO slightly in overcast or shaded conditions.
The knurled non-slip pattern on the frame gives you a firm grip even on compact lenses, making it straightforward to dial in the polarization effect without fumbling.
You get the CPL filter, a microfiber lens cleaning wipe, and a protective filter case for storage and transport.
