Hoya 49mm HMC UV-IR Digital Multi-Coated Slim Frame Glass Filter

This specialized Hoya 49mm HMC UV-IR Multi-Coated Filter has the ability to cut out both UV rays below 390nm and IR rays above 700nm leaving just the light rays in the visible spectrum passing through the filters and into the camera. This is important because CCD and CMOS sensors are extremely susceptible to UV and IR rays just outside the visible spectrum that have a very negative impact on image quality. The Hoya UV & IR Cut filter blocks both UV rays and IR rays yielding clearer and sharper pictures outdoors. This filter can reduce the effects of atmospheric haze to an even greater degree than a standard UV filter. In addition, this filter is multi-coated, which greatly reduces lens flare and ghosting, and the slim frame helps avoid vignetting on super wide angle lenses. And of course, this filter will protect your lens surface from dust, moisture and other contaminants. Key Features: • Multi-coating greatly reduces lens flare and ghosting • Slim filter frame helps avoid vignetting on super wide angle lenses • Blocks both UV rays and IR rays yielding clearer and sharper pictures outdoors • Protects your lens surface from dust and scratches The Hoya UV & IR light transmission curve shows the sharp-cut nature of the filter glass and coatings as well as the consistent light transmission in the visible spectrum. This curve demonstrates a more even light transmission than the closest competitor. This means that sharper images with more depth and finer, richer color gradations are possible with the Hoya UV & IR Cut filter.
