- Three extra-low dispersion elements are used to greatly reduce color fringing and chromatic aberrations in order to produce high clarity and color fidelity throughout the zoom range.
- Three aspherical elements control distortion and spherical aberrations, which helps to improve sharpness and realize more accurate rendering.
- Nano-GI (Gradient Index) coating has been applied to lens elements and alters the refractive index between the glass and air in order to better suppress lens flare and ghosting for diagonal incident light.
- A Twin Linear Motor autofocus system delivers smooth, near-silent performance that is especially beneficial to video applications and when working in noise-sensitive areas.
- Rounded nine-blade diaphragm contribute to a pleasing out-of-focus quality to benefit the use of selective focus and shallow depth of field techniques.
- The lens body incorporates extensive weather sealing to protect against dust and moisture, and to enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.
The Pro 77mm 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.

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.
Keep your optical surfaces clean with the Sensei OC-CK Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, bulb air blower, paint brush, lipstick brush, lens cleaning fluid, microfiber cleaning cloth, and see-through mesh travel case to put everything in. This kit can be used to clean a variety of different optics and glass. You can use the air bulb blower and any of the three supplied brushes to initially remove dust from the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints from the glass. For those more stubborn blemishes or smudges, the lens pen is very effective.
