The 77mm 90-UVAT UV Filter from Chiaro is their entry-level protective UV filter offering 90% light transmission. It’s ideal for photographers who demand the highest-quality glass and other essential features for uncompromised image fidelity and premium construction.

To achieve 90% light transmission, Chiaro uses highly-polished optical glass and additional advanced elements that improve the filter’s light transmission. A hard-anodized aluminum filter ring is easy to screw on and off, and it’s thin enough to shoot with a wide-angle lens without vignetting. 

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.

90% Light Transmission
Protect your lens while maintaining optical quality. By using highly-polished optical glass, Chiaro offers a 90% transmission rate. And the company verifies the ratings with ISO certified lab testing.
Polished Optical Glass
Polished glass is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is polished for flatness that ensures optical clarity.
UV Protection
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.
Slim Design
Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
Top Knurling
Top knurling offers a firm grip on the filter when you're attaching or removing it.
Secure Attachment
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.
Front Threads
The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.

You wouldn't, Chiaro does have a higher light transmission filter. A 95%, 98%, and a 99%. High-quality filters will cost more.

What are the differences between UVAT, UVBTS, and UV MRC filters?
Asked by: Mark D
The "AT" refers to the construction of the filter ring as aluminum with top knurling. "BTS" means brass with top and side knurling. "MCR" refers to multi resistant coating but the Chiaro 82mm 90-UVAT UV Filter is not an MRC filter.
