Hoya 82mm HMC Close-Up Filter Set II (+1, +2, and +4)
The Hoya 82mm HMC Close-Up Filter Set II (+1, +2, and +4) are renowned for their ability to minimize 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 color. HOYA HMC filters are recommended for enhancing the performance of today’s multicoated lenses. The set includes +1, +2, and +4 diopters for close-up photography. Depth-of-field is shallow so use as small an aperture as possible, CLOSE-UPs offer a world of new creativity.A close-up filter is a magnifier that optically decreases the focal length of a camera lens placed behind it. This effect lessens the minimum focus distance between the camera lens and a subject. The magnifying power of a close-up filter is indicated by its diopter strength. A close-up filter with a higher diopter number provides more relative magnification and can be combined with other close-up filters to increase, or fine-tune the macro effect. These close-up filters have diopter strengths of +1, +2, and +4.Features: Produces macro-like results for camera lensesStrengths of filters can be combined to vary and modify the desired close-up effectMade of optical glass with three layers of anti-reflection coatingsImproved clarity and effective prevention of internal ghosting and reflections97% average light transmissionHas aluminum-alloy filter ring for durability while remaining lightweight
