Two 39mm camera filters UV and CPL in kit

Urth

Urth 39mm Duet Filter Kit UV CPL camera filter

SKU CH-Z7XG-DHH39

A 39 mm kit pairing a UV filter that blocks 99.6 % of UV haze with a CPL filter to cut reflections and boost colour saturation

  • Protects lens from scratches, dirt and moisture
  • Removes 99.6% UV haze for crisp, cast-free images
  • Japanese AGC optical glass with 8-layer nano-coating sharpens detail
  • Ultra-slim magnalium rim prevents vignetting on wide angles
  • Double-threaded design allows stacking filters or screw-mount caps

Kit contents and purpose

The Urth 39mm Duet Filter Kit pairs a UV filter with a circular polarising filter for 39mm lens threads. Photographers who want lens protection and reflection control in one purchase receive both tools in a single kit. The combination suits outdoor and travel shooting where haze and glare are common. Buyers needing filters for a different thread size cannot use this kit.

Optical glass and coating performance

Each filter uses Japanese AGC optical glass with an 8-layer nano-coating that removes 99.6% of UV haze and sharpens images in hazy conditions. The coating also resists moisture and makes cleaning straightforward. No power draw, thermal output or fan noise exists because these are passive glass accessories. The ultra-slim magnalium rim is designed to avoid vignetting on wide-angle lenses.

Double-threaded rim utility

Both filters feature double-threaded rims so a second filter or a screw-mount lens cap can be stacked without removing the first. This allows the UV shield to stay in place while the CPL is added for polarisation. Photographers who rely on filter holders or non-threaded systems gain no benefit from the double-thread design.

Questions about this item

How do I install the 39mm Duet filters and avoid cross-threading the ultra-slim magnalium rim?

Align the filter threads carefully with the lens barrel, turn gently until resistance drops, then rotate smoothly; the double-threaded design accepts lens caps or stacked filters without forcing the thin rim.

What maintenance will the UV and CPL filters need over time?

Clean the 8-layer nano-coated Japanese AGC glass with a blower and microfibre cloth; the coating resists water and oil, so fingerprints wipe off without solvents.

What limits the CPL filter during long shoots in bright conditions?

The polariser darkens the scene by about one to two stops, so exposure times lengthen and motion blur can appear before the filter itself degrades.
