Hoya Revo £115, $175
for 77mm fitting
Costing nearly twice as much as the Hoya Pro1 Digital circular polariser, this recently launched filter is from Hoya’s new ‘Revo’ range. Mechanical design and build quality feels identical, with the same low-profile dimensions, black-rimmed glass and matte black aluminium frame. Like the less expensive Pro1 Digital filters, it’s also made in Japan and comes in a UV-resistant case.
The principal difference is that the Revo filter uses upgraded glass and coatings. Hoya claims that the high-precision optical glass is specially smelted and blended to yield perfect results, and that the Super Multi-Coating is more effective in eliminating reflections. The coatings are also overlaid with an additional water and stain-resistant coating, which is easier to clean.
Upmarket coatings make the filter very non-reflective. It’s available in sizes from 37mm to 82mm
