The ad­ver­tised stop­ping power of this vari­able den­sity fil­ter is less than that of the Light Craft Work­shop fil­ter, at two to six stops. In our tests, how­ever, both gave prac­ti­cally iden­ti­cal max­i­mum re­duc­tions at vary­ing fo­cal lengths. The For­matt-Hitech’s con­struc­tion boasts ‘high­est qual­ity broad­cast glass’ built into to an alu­minium hous­ing.

The over­all build is quite chunky, based on a pair of rings, one fixed and one ro­tat­ing. How­ever, the front ring is con­sid­er­ably larger in di­am­e­ter than the rear one, which helps to avoid vi­gnetting when at­tached to wide-an­gle lenses. The colour ac­cu­racy and over­all im­age qual­ity pro­duced are prac­ti­cally iden­ti­cal to those of the less ex­pen­sive Light Craft fil­ter, but the For­matt-Hitech feels a lit­tle more ro­bust.
