20 Oct Irix announces 100mm filter system for wide angle lenses
Source: DP Review
Lens manufacturer Irix announced earlier today that it plans to release a filter holder and a collection of filters in 100x100mm and 100x150mm sizes—a system designed especially to fit its 15mm F2.4 lens. The holder accepts a special bayonet mount adapter to attach to the front of the 15mm lens, while a range of additional screw thread adapters will allow the holder to be used with other lenses.
The Irix Edge 100 system will consist of a dual slot holder that the company claims is the lightest in its class. The holder is made from ‘aluminium alloy’ and features a rotating joint to allow easy positioning of graduated filters and polarisers.
Irix says that the holder, called the IFH-100, has a profile that’s slim enough to avoid mechanical vignetting even when two filters are held in front of the 15mm lens, and that a layer of black velvet covering the forward surfaces prevents light leak during long exposures.
The filter system includes 2mm-thick filters in the 100x100mm and 100x150mm sizes—to begin with the company will launch mostly NDs, ND grads and a polarizer, but has plans to offer a filter that cuts the effect of pollution. The holder accepts filters from other systems as well, and the company plans to offer adapter rings for lenses with threads of between 67mm and 82mm. Irix already has a series of circular screw-in filters under the Edge brand.
Price and availability have yet to be announced…
