Progrey G-100Z Filter Holder - NEW!
Introducing the new Progrey G-100Z filter holder! The G-100Z 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 "Antarctic" cpl filters and the Progrey "Antarctic" ND filters which have a magnetized ring. The filters are simply held up against the G-100Z adapter and 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.
Of course you can still use 2mm thick flat slide-in filters of 100mm width, such as Progrey Aurora or Titan GND or Reverse GND filters, up to 3 at a time, in addition to 2 magnetic round Antarctic filters..
