Hoya HMC - ULTRA Skylight 1B (Pink) - 72mm

Reduces the excessive bluishness that frequently occurs in outdoor color photography, especially in open shade under a clear, blue sky. The absorption peak is in the range which corresponds to the film's green spectrum. This means outstanding outdoor shots with superb color balance and clarity under all conditions. Also keeps skin tones free of colored reflections from nearby objects such as the shade of trees.

Filters in this series use HOYA new ULTRA thin rings which, like the Super PL-CIR filter, are designed primarily to avoid vignetting problems which occur with wide angle lenses. The ULTRA series filters use rings just 3mm in thickness, except for the hybrid UV/Polariser which has a 5mm rotating ring. HMC Multicoating is applied to both sides of the filters and they are supplied with HOYA push-on lens caps. The Ultra ND filters use new Multi-Layer Coating technology to produce a neutral transmission curve which gives perfect color balance. They have also introduced hybrid filters in the ULTRA series, these combine the effect of two filters in one (i.e.: PL-CIR and UV together). This means that HOYA ULTRA series filters are the ultimate choice for wide angle lenses - there is no other filter available to exceed the ULTRA specification.
