Progrey G-120Z Filter Holder - NEW!
Introducing the new Progrey G-120Z filter holder! The G-120Z includes the same components as the NEW G-100Z but accommodates 120mm wide flat filters. 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-120Z filter holder is ideal for use on extreme wide angle lenses that have a "threaded lens barrel", especially on full frame sensor cameras, as well as normal to telephoto focal lengths. It is a perfect choice for lenses as wide as 16mm on a full frame camer.. Because of the extra wide diameter, there is less chance of vignetting when attached to extreme wide angle lenses. Consider this filter holder system if your widest angle lens is 16mm and has a filter thread lens barrel.
The G-120Z differs from it's former sister product, the G-120X, in several ways. The biggest difference is the new, revolutionary method of attaching round ND filters and round polarizer filters. The G-120Z accepts the new, advanced Progrey "Antarctic" cpl filters and the Progrey "Antarctic" ND filters, both of which have a magnetized ring. The filters are simply held up against the G-120Z 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-120Z has a larger and more easily accessible knurled knob for tightening or adjusting the 120Z adapter. More efficient than the G-120X system.
Progrey "120-Z" series adapters (sold separately) must be used to attach the G-120Z to your lens. These G-120Z adapters have knurled edge grooves so that adjustment of an attached polarizer is fast and easy.
Of course you can still use 2mm thick flat slide-in filters of 120mm 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..
