The best filters Rollei has ever built
Soft gradient filters are used to compensate for differences in brightness in the motif, e.g. in rugged mountain landscapes,
forest areas, motifs without clearly defined horizon
Ultra-fine coating ensures razor-sharp images – even with 150 MP high-end cameras
Exemplary colour fidelity – capturing nature as it is seen by the eye
Impressively clear images thanks to approx. 99.5 percent absence of reflection
Diamond-like scratch resistance – extremely hard surface coating for optimum protection
Extremely temperature resistant – tested in scorching heat and freezing cold
Original Gorilla®* glass – legendary resistance and break resistance
Modus operandi
GND filter is the abbreviation for “graduated neutral density filter”, also called grey graduated filter.
A grey graduated filter is employed to balance the difference in brightness of the horizon. Generally, a soft GND filter is used to take shots whenever the sky is much brighter than the land or vice versa, when the city is much brighter than the sky.
This filter then has the same effect at the top edge as a grey filter; this effect attenuates uniformly towards the bottom.
