Urth Lens Filters & Camera Accessories
Urth — formerly Gobe — is a certified B Corp and purpose-driven optics brand that plants trees with every purchase and manufactures premium lens filters from Japanese optical glass. Their lineup includes circular polarizers, UV filters, ND filters, variable NDs, and magnetic filter systems, all built to a standard that rivals far more expensive European alternatives. For photographers who care about both image quality and environmental impact, Urth strikes a compelling balance.
What Makes Urth Filters Different
Urth uses AGC optical glass from Japan — the same glass used by major Japanese lens manufacturers — and applies multi-layer nano coatings that repel water, oil, and dust while minimizing flare and ghosting. Their frames are precision-machined from aluminum alloy and feature ultra-slim profiles designed to prevent vignetting on wide-angle lenses. Unlike budget filter brands that use B270 glass or plastic elements, Urth's glass is optically clear, color-neutral, and consistently rated for sharpness that won't compromise your lens's resolving power.
Buying Guide: Choosing Urth Filters
UV Filters
Urth's UV filters serve as both lens protection and a subtle UV light block. At their Plus+ tier, you get a 20-layer multi-resistance coating that exceeds most competing UV filters in flare and ghosting control. These are the ideal always-on lens protection for photographers who don't want a bare front element.
Circular Polarizers
A circular polarizer (CPL) is one of the few filters that can't be fully replicated in post. Urth's CPL filters cut glare off water and glass, deepen blue skies, and make foliage pop. At 16 layers of coating, the Plus+ CPL maintains outstanding light transmission while delivering the saturation boost landscape photographers depend on.
ND Filters & Variable NDs
Urth's fixed ND filters come in ND4 through ND100000 densities, covering everything from waterfall and motion blur work to midday video shooting. Their variable NDs offer a twist-dial density range and are available in standard and Plus+ tiers. For video shooters, the variable ND is an essential tool for maintaining proper exposure across changing light conditions without touching the aperture.
Magnetic Filter Systems
Urth's magnetic filter system starts with a slim magnetic adapter ring that attaches to your lens. From there, you snap on CPL, ND, or UV filters without threading — a major time-saver when swapping between filter types on location. The system is compatible across all filter sizes, so one set of 82mm filters can work on multiple lenses with the right adapter rings.
What filter thread size do I need for my lens?
The filter thread size is printed on the front of your lens barrel — look for the diameter symbol followed by a number in millimeters (e.g., 67mm, 77mm, 82mm). Common sizes are 49mm, 52mm, 58mm, 67mm, 72mm, 77mm, and 82mm. Urth makes filters in most common sizes. If you have lenses with different front diameters, step-up rings let you use a single larger filter across all of them.
What's the difference between Urth's standard and Plus+ tiers?
Urth's standard filters use high-quality AGC optical glass with multi-layer coatings. The Plus+ tier adds more coating layers (up to 20+), tighter manufacturing tolerances, better flare suppression, and slightly higher light transmission. For most general photography and video, the standard tier performs excellently. Plus+ is worth it for demanding situations where you absolutely cannot afford flare or color cast — sunrise/sunset landscapes, shooting near strong light sources, and critical video color grading.
Are Urth CPL filters good for video?
Yes. Urth's circular polarizers work equally well for photo and video. They're particularly useful for outdoor video shooting to manage reflections on windows, wet surfaces, and water, and to maintain consistent sky color. The 16+ layer coatings on Plus+ CPL filters minimize the greenish or warm color cast that cheaper CPLs sometimes introduce.
How does Urth's environmental mission work?
Urth partners with eden reforestation projects and plants trees with every product purchase. They are a certified B Corp, meaning they meet rigorous standards for environmental and social responsibility. Buying an Urth filter is a way to support reforestation while getting a premium optical product — a mission that resonates with many outdoor and nature photographers.
Can I use Urth filters on any camera brand?
Yes. Urth filters thread onto any lens with a matching front filter diameter, regardless of camera brand or mount. They work with Sony, Canon, Nikon, Fujifilm, Panasonic, Leica, and any other system. The only variable is the thread size, which differs by lens.
