UV (Haze) 1A Multicoated Glass Filter 37mm - Slim Multithreaded Design

Our review of the UV (Haze) 1A Multicoated Glass Filter for Leica D-LUX 6 finds it is a practical, no-nonsense accessory for photographers and videographers who want optical protection without altering exposure. The Grade 010 specification means the filter is effectively neutral, so users can leave it on as a protective element without changing color or brightness. Built with a rugged metal ring and heat treated glass, this filter is primarily for shooters who value durability and a slim profile that minimizes vignetting when using wide focal lengths.

Key Features

• Grade 010 (Filter Factor 0 Zero): preserves the original exposure so photographers can use it continuously without recalculating settings.
• Rugged metal filter ring: the black finish and solid construction offer reliable thread engagement and resistance to dings during field use.
• Heat treated glass: increases durability and resists scratches better than untreated optical glass in daily handling.
• Slim design minimizes vignetting: the thin profile helps maintain corner illumination on wide-angle shots for compact cameras like the D-LUX 6.
• Multicoated surfaces: reduce reflections and flare for cleaner images in both photography and video workflows.
• Multithreaded construction: allows use with adapter rings and accessories without cross-threading or fit issues.

Who It's For

This filter is well suited to street photographers, travel shooters, and videographers using a Leica D-LUX 6 or similar compact cameras who want constant lens protection with minimal impact on image quality. Its neutral Grade 010 specification means it is ideal for users who do not want to compensate for exposure or color shifts during shoots.

It is less relevant for photographers seeking creative filtration (warming, cooling, or strong UV correction) or those who require specialized filters for long exposures. Professionals who demand multi-stop filtration or variable ND control should look to dedicated neutral density or effect filters instead.

Pros & Cons

Pros

• Durable metal ring and heat treated glass provide solid everyday protection for the lens front element.
• Slim profile reduces the risk of vignetting on wide-angle settings, maintaining image corners.
• Multicoating lowers flare and reflections, helping keep contrast in backlit scenes.
• Multithreaded design improves compatibility with adapter rings and accessories.

Cons

• Grade 010 provides no exposure or optical correction benefit, so it is purely protective rather than corrective.
• Limited to 37mm mount size and the supplied adapter ring for this camera, so users of other lenses must confirm compatibility.
