Progrey G-100Z Filter Holder - NEW!
The MAGNETIC filter system by Progrey began as an innovative idea back in 2014. Now in it's 2nd generation, with refinements made after extensive testing, the Progrey G-100Z and G-120Z systems and rapid-attach magnetic Antarctica filters are finally available worldwide through ProgreyUSA.
The new Progrey G-100Z filter holder accommodates 100mm wide flat filters, just like it's sister product the G-100X. It includes a pair of double clips and a pair of triple clips for using up to 3 slide-in filters at a time.
The Progrey G-100Z filter holder is ideal for use on lenses as wide as 18mm that have a "threaded lens barrel", especially on full frame sensor cameras, as well as normal to telephoto focal lengths. Consider this filter holder system if your widest angle lens is 18mm (on a full frame sensor) or 12mm (on a crop sensor) and has a filter thread lens barrel.
The G-100Z differs from it's former sister product, the G-100X, in several ways. The biggest difference is the new, revolutionary method of attaching round ND filters and round polarizer filters. The G-100Z accepts the new, advanced Progrey "Antarctica" cpl filters and the Progrey "Antarctica" ND filters. These filters have a magnetized ring and are simply held up against the G-100Z adapter to immediately attach via a secure magnetic attraction. No more fumbling to carefully screw-in fine-threaded filters with freezing fingers. The attachment is instantaneous, meaning you won't waste time and "miss the shot" by carefully screwing in a threaded filter.
Also, the G-100Z has a larger and more easily accessible knurled knob for tightening or adjusting the 100Z adapter. More efficient than the G-100X system.
Progrey "100-Z" series adapters (sold separately) must be used to attach the G-100Z to your lens. These G-100Z adapters have knurled edge grooves with an internal rotating ring so that adjustment of an attached polarizer from behind the camera is fast and easy.
