The HOYA PRO 1D DHMC UV filter belongs to the category of multipurpose photo filters suitable for day-to-day photography, which means it needn't be removed from the lens at all. With this filter, it's possible to achieve better image clarity and more accurate colour balance. When applied, the UV filter absorbs ultraviolet light that often makes photos blurry or otherwise unclear, and it's suitable for black and white as well as colour photography. Another advantage of the UV filter is that it makes the lens more resistant to physical damage such as scratching.
Filters with DHMC surface coating excel in their ability to minimise surface reflection and therefore reduce excessive brightness and sharpening. Due to the DHMC multi-layer coating, the filters boast a very high level of light transmission, which means Hoya UV filters provide crisp, high-contrast images with perfectly balanced colours.
The PRO 1D series offers filters with a 1mm optical glass that are specially designed for use with devices with CCD or CMOS sensors.
