Hoya HMC Close-Up +1+2+4 Set II 82mm

overview

The HMC Close-Up Filter Set II offers the ability to achieve macro-like results with camera lenses. 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. Magnification can then be obtained by decreasing the distance between the subject and the combined camera lens and close-up filter.

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.

These popular filters 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.
