The Hoya 55mm HD3 UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections while providing over 99.7% light transmission, 16 layers of anti-reflection nano coatings are applied to each side. This total of 32 coatings offers a high degree of protection to the filter substrate and helps it to stay clean for longer than uncoated filters. The nano coating formula associated with HD3 UV filters results in an improved beading effect when in contact with water for greater cleaning efficiency and is also effective with regard to oil and stains.

Constructed from chemically-hardened optical glass, the Hoya 55mm HD3 UV Filter offers enhanced resistance to scratches while providing clarity and color fidelity. It also features a thin, lightweight, aluminum-alloy filter ring to minimize the potential for vignetting.

This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.

Q: 1. Does this particular filter downgrade image sharpness in any way vs. not using a filter at all?

A: Technically, any glass layer in a lens system scatters light and decreases sharpness. However, the reality is good filters will not affect sharpness to any degree you can see. Frankly, other factors such as camera shake, focus, subject movement, aperture, lighting and contrast have far greater influence on image sharpness than a quality filter such as this one.
