Urth ND1000 Filter Plus+ £26+£108/$34-$154

This 10-stop ND filter comes in a range of sizes, is well-priced and produces great results

At the end of 2020, the filter, strap and bag manufacturer Gobe rebranded itself as Urth. The new name reflects the fact that Urth is a community of creators who are  inspired by planet earth and who intend to plant one billion trees by 2032. The company aims to make a positive impact on the planet by manufacturing products from low-impact materials and following sustainable principles.

Urth makes an extensive range of filters, including five different strengths of circular neutral density filter, running from ND4 (2 stops) to ND1000 (10 stops), as reviewed here. There’s also an ND64 (6-stop) filter that combines the neutral density filtration with a circular polariser. In addition to the circular filters, Urth makes 100mm-type square filters and there are five strengths of ND from 2-stops to 10-stops available. As one of Urth’s Filter Plus+ filters, the ND1000 Filter Plus+ is made from German Schott B270 glass rather than the cheaper Japanese Schott glass which has a slightly lower light transmission and is used for the standard Urth range of filters.

The glass has a 20-layer nano-coating for better light transmission and easier cleaning. Meanwhile, the slim rim is made from an aluminium and magnesium alloy and is guaranteed for life. It also has a thread on either side to enable the filters to be stacked if required.

"With 18 sizes, it's a strong possibility there's a filter to fit every lens you own"
