These filters offer both amateur and professional photographers HOYA's famous quality at reasonable prices. They have coatings applied to both surfaces to suppress reflection and increase light transmission.
The Hoya HMC 81 is a light balancing filter used to decrease the colour temperature slightly for a warmer (redder) tone. It is available in 3 strengths (A, B and C); 'A' being the mildest warming effect and 'C' the strongest.
HOYA HMC filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced colour. HOYA HMC filters are recommended for enhancing the performance of todays multicoated lenses.
