Tiffen Pro100 ND Starter Kit

£259/$300

Tiffen’s kit packs a single 4-stop soft-graduated filter, and one standard 4-stop full ND for long exposures. Both filters are 100mm square, so while they’re large enough to cover most wide-angle lenses, you don’t get the vertical positioning flexibility of the 150mm-tall Lee filters. Tiffen’s glass is unusually thick, though, and it’s held in a high-quality bundled holder. You also get 77mm and 82mm adaptor rings.

Sadly, optical quality isn’t so impressive. The ND grad generated an obvious yellow cast, to the point it could almost be a dedicated warming gel, and there’s only a 4-stop light reduction at the very edge of the filter.
