The Pro 43mm 98-UVAT UV Filter is one of Chiaro’s highest-rated protective UV filters with 98% light transmission. It’s ideal for photographers who demand high-quality glass and other essential features for excellent image fidelity and construction.

To achieve 98% light transmission, Chiaro uses highly-polished optical glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. Resistance coating improves the scratch resistance of the glass, and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. A hard-anodized aluminum filter ring is designed to screw on and off effortlessly, and it’s thin to prevent vignetting when used with wide-angle lenses.

Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.

Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished optical glass and advanced coatings, Chiaro offers a 98% transmission rate, which is an excellent transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.

The layers of advanced resistance coating on the filter are designed to resist moderate scratches, and allows you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.

Glass that's polished to perfection is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is highly-polished for flatness that ensures excellent optical clarity.

Multi-coating enhances light transmission to the demanding level set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.

The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.

The process of hard anodizing toughens and strengthens the aluminum for a lightweight yet durable filter ring.

Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.

Top knurling offers a firm grip on the filter when you're attaching or removing it.

It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.

The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.
