Hoya Pro ND 1000
£165, $120 for 77mm fitting
Something of a household name, Hoya filters have long been popular with photographers all around the world. A wide range of Pro ND filters are available in increments from two- to 10-stop options, each of which uses the same ‘Metallic ACCU-ND’ type of coating. Hoya claims that this not only yields a truly neutral colour balance without any noticeable colour casts, but also maintains colour integrity between different strengths of filter.
In our tests, we found that the Hoya 10-stop filter gave the most accurate colour rendition of any filter in the group on both our cameras. Its profile isn’t quite as slim as those of some of the competing filters but we still didn’t experience any vignetting, even when using the Hoya on ultra-wide lenses.
