Urth 55mm 3-in-1 Lens Filter Kit - UV, CPL, ND2-400

The UV filter protects your lens and can enhance clarity. The CPL filter reduces reflections and glare, improving color saturation. The Variable ND2-400 allows you to control the amount of light entering the lens, enabling motion blur and wider apertures in bright conditions.

This kit is designed for lenses with a 55mm filter thread. Look for a marking on your lens barrel, usually a circle with a line through it followed by '55' (e.g., ø55mm).

You can stack the UV and CPL filters. The Variable ND filter is designed to be used on its own. Stacking the Variable ND with other filters may cause severe vignetting or an 'X' pattern.

It means the filter can reduce light by 1 to 8 stops. ND2 offers a minimal reduction (1 stop), while ND400 offers a significant reduction (approximately 8 stops), allowing for much longer exposures or use of wider apertures in bright light.

The filters are constructed with durable magnalium frames and 8-layer nano-coated Japanese AGC glass, designed for resilience in various outdoor shooting conditions.

Urth offers a lifetime warranty on these filters, providing long-term protection and support.

This is a common characteristic of variable ND filters. Rotate the filter ring to a slightly lower ND setting until the 'X' pattern or color shift disappears. Ensure you are not pushing the filter to its absolute maximum range.

Ensure the filter rim is not obstructing the view. While designed to be ultra-slim, vignetting can occur on very wide-angle lenses or when stacking filters. Try removing the filter or using it on a lens with a longer focal length. Check that the filter is screwed on straight.

Ensure the filter glass is clean. Smudges or dust can reduce sharpness. Also, verify the filter is screwed on straight and not cross-threaded. For critical sharpness, ensure the filter is the correct size for your lens.
