Urth Plus+ 77mm UV Lens Filter

Urth Plus+ is a 77mm UV lens filter intended to shield a compatible camera lens and reduce ultraviolet haze. Its listed optical-glass construction and slim rim are aimed at photographers who want a protective filter without a bulky profile.

At a glance

The listing describes a slim-rim design intended to reduce vignetting, particularly relevant when using wider-angle lenses.
Urth claims the 30-layer nano-coating cuts flare and supports light transmission. These are manufacturer claims, not independently verified results.
A 1 x filter factor is listed, so the supplied details do not indicate a stated exposure reduction.

What to know before buying

Listing details to confirm

Listing details conflict or are inconsistent: the UV filter is listed as 3.03 Inches screen size, and the A+ copy describes 20-layer nano-coating while the title and specifications state 30 layers. The listing also does not clarify whether the claimed water resistance applies to the filter or its coating. Verify these details if they matter to your purchase.

Who is it for?

A good fit for

Photographers with a lens that has a 77mm filter thread who want a UV filter that can also act as a front-element barrier.
Buyers who prefer a slim filter rim for use with wider-angle lenses.

Less suited to

Owners of lenses with a thread size other than 77mm unless they have a suitable step-up or step-down adapter.
Photographers seeking a variable exposure-control filter, as the listed effect is ultraviolet and the factor is 1 x.
