New UV & IR Cut filter
HOYA introduces the new Hoya UV & IR Cut filter in  sizes from 49mm through to 82mm.
The new UV and IR Cut Filter from Hoya is a  lens filter that, when attached to your lens, permits only the visible spectrum  of light rays to enter the camera and get captured by the sensor. It blocks out  both the higher frequency ultraviolet rays and lower frequency infrared light  rays. This is important to digital photographers as the CCD and CMOS sensors  found in our cameras are extremely susceptible to catching UV and IR rays just  outside the visible spectrum that have a very negative impact on image quality.
  The filter offers even greater versatility than is already found in a  combination UV-IR filter due to its front and rear threads. They permit  stackable standard-size filters to be attached, giving you even more filter  effect options, while also accommodating a standard lens cap as well.
  Another benefit to using the UV-IR filter is that it can also reduce the  effects of atmospheric haze to a greater degree than would be found with a  standard UV filter. This means that sharper images with more depth and finer,  richer colour gradations are possible when utilizing the filter's effects in  your photography. This combination filter is a convenient option for those who  seek a clearer and sharper image when captured outdoors, while getting the  benefits of two filters in one.
  The filter is available immediately. 
  Suggested retail prices start from £84.99 for the 49mm size.
