Product Information

Full details

The Urth 43mm Plus+ Circular Polarising Filter is designed for professional creators seeking superior color accuracy and contrast. It effectively reduces glare and reflections from non-metallic surfaces, enhancing saturation and detail in your images. While offering exceptional quality with German Schott glass and advanced multi-layer coating, its primary caveat is the fixed 43mm thread size, requiring specific lens compatibility or adapter use.

FAQs

What is a Circular Polarizer (CPL) filter used for?

A CPL filter is used to reduce glare and reflections from non-metallic surfaces like water and glass, and to enhance color saturation and contrast, particularly in skies and foliage.

How do I know if this 43mm filter will fit my lens?

This filter has a 43mm thread size. It will fit directly onto lenses with a 43mm front filter thread. You can find your lens's filter size by looking for a symbol like 'ø43mm' printed on the lens barrel or cap.

Can I use this filter on lenses with different thread sizes?

Yes, you can use compatible step-up or step-down adapter rings to attach this 43mm filter to lenses with different filter thread sizes.

How do I clean the filter effectively?

Use a soft, lint-free microfiber cloth to gently wipe the lens. For stubborn marks, use a dedicated lens cleaning solution applied sparingly to the cloth, or use distilled water. Avoid abrasive materials.

What does the 'Plus+' designation mean?

The 'Plus+' designation typically indicates Urth's higher-tier filters, featuring premium Schott glass and their advanced CoraNano 20-layer dual-side coating for superior optical performance and durability.

Does this filter reduce the amount of light entering the lens?

Yes, CPL filters reduce light by approximately 1 to 2 stops. This is a normal characteristic and should be accounted for in your exposure settings.

What is the Urth 'Plant 5 Trees' initiative?

Urth partners with local communities to plant 5 trees for every filter purchased, contributing to reforestation efforts in deforested regions.

Troubleshooting

Filter does not screw on smoothly

Ensure you are using a lens with a 43mm filter thread. Check for any debris on the lens threads or filter threads. Attempt to screw it on straight without forcing it.

No noticeable change in reflections or color

Rotate the outer ring of the filter while observing your subject. The polarizing effect is angle-dependent and works best when the filter is oriented at 90 degrees to the light source causing the reflection or glare. Ensure the effect is not being cancelled out by a linear polarizer on another lens or by the camera's internal polarization.

Image appears dimmer than expected

Circular polarizers can reduce light transmission by approximately 1 to 2 stops. This is normal. Adjust your exposure settings accordingly. If the dimming is excessive, ensure the filter is clean and properly seated.

Visible vignetting (dark corners) on wide-angle shots

This filter has a slim profile, but stacking filters or using very wide-angle lenses may still cause vignetting. Try removing other filters or using a lens with a narrower focal length. On some cameras, you may be able to correct slight vignetting in post-processing.

Pros and Cons

Pros

  • Exceptional clarity and color accuracy due to premium Schott glass.
  • Advanced multi-layer coating minimizes unwanted reflections and flare.
  • Noticeably enhances color saturation and image contrast.
  • Durable construction with a lifetime warranty.
  • Contributes to environmental reforestation efforts.

Cons

  • Fixed 43mm filter thread limits direct compatibility with lenses of other sizes.
  • Requires careful rotation to achieve optimal polarization effects.
  • Higher price point compared to basic CPL filters.
  • 20-layer coating, while advanced, can still be susceptible to deep scratches if not cared for.

Setup, Compatibility & Care

Setup: Screw the Urth 43mm Plus+ CPL Filter directly onto the front filter thread of your 43mm lens. Ensure it is screwed on evenly and securely to avoid cross-threading. Once attached, rotate the outer ring of the filter to adjust the polarizing effect. Observe the effect in your camera's viewfinder or on the live screen to achieve the desired outcome.

Compatibility: This filter is designed with a 43mm thread size. It will directly fit lenses with a 43mm front filter thread. For lenses with different thread sizes, use a compatible step-up or step-down adapter ring. Check your lens specifications for the correct filter thread diameter.

Care: To maintain optimal performance and longevity:

  1. Cleaning: Gently wipe the filter surface with a soft, lint-free microfiber cloth. For stubborn smudges, slightly dampen the cloth with lens cleaning solution or distilled water. Avoid pressing too hard.
  2. Storage: Store the filter in its protective case when not in use to prevent scratches and dust accumulation.
  3. Handling: Handle the filter by its edges to avoid transferring oils from your fingers onto the glass surface.
