Chiaro 43mm 98-UVATS UV Filter
The 43mm 98-UVATS UV Filter is one of Chiaro’s highest-rated protective UV filters with 98% light transmission. It’s ideal for photographers of all levels 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. A scratch-resistant coating minimizes scratching of the glass and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. Its hard-anodized aluminum filter ring is designed to screw on and off effortlessly, and it is thin to prevent vignetting when used with wide-angle lenses. Side knurling helps assure that you’ll have a firm grip when attaching or removing your filter.
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.
98% Light Transmission
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.
Polished Optical Glass
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.
Hard Anodized Aluminum Construction
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 and Side Knurling
In addition to top knurling, Chiaro added side knurling that helps offer better options to grip the filter when you're attaching and removing it, or when you're stacking filters.
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.
Sensei BOC-CK Basic Optics Care and Cleaning Kit
Keep your optical surfaces clean with the Sensei BOC-CK Basic Optics Care and Cleaning Kit, which contains a pack of lens tissues, a microfiber cleaning cloth, a blower/brush, cotton swabs, and lens cleaning fluid. This kit can be used to clean a variety of different optics and glass, use the blower/brush to initially remove dust on the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the microfiber cleaning cloth or lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints on the glass. The cotton swabs provided are used for those hard-to-reaches areas where the cloth or the tissues cannot reach, such as the crevasses or corners of a lens.
