The Progrey G-85X holder includes 2 pairs of filter clips which are easily interchangeable: a single filter clip (with one rail for 1 slide-in filter) and a double filter clip (with two rails for 2 slide-in filters). Stacking multiple flat filters has never been easier! The G-85X holder also includes extra screws and an allen wrench for easy exchanging of filter clips.
The Progrey G-85X holder allows the use of 85mm wide slide-in filters - a very popular and versatile size for both full frame and crop sensor cameras. This size is also widely known as "P" series.
The G-85X system is unique, allowing a full range of "S" series ultra slim adapters without front threads for cirular filters (circular filters can be attached between adaptor and lens, however). The G-85X system is ideal if you're not using ultra-wide angle lenses on full frame sensors and if you seldom use circular (round) filters.
Adapters must be used to attach the G-85X holder to your lens. These affordable, light weight adapters are sold separately and are lens-size specific. A huge selection of adapter sizes are available. Simply determine the screw-in filter size of your lens barrel and that is the adapter size you need for that lens.
