Irix has augmented its filter line-up with the introduction of a new ND filter.
The Irix ND32000 filter has an optical density of 4.5 and reduces incoming luminous by 15-stops which means that even on sunny days, you can get exposure times of up to five minutes.
Thanks to a momentous waterproof and oil repellent NANO coating, the filter's surface is protected from stains and fingerprints. It's also a screw-on seep which will minimise light leakage.
The retail price for the Irix Edge filter ND32000 is 159 euros and it will be at soon.
