- Featuring a combination of two Super ED and six ED glass elements, chromatic aberrations and color fringing is effectively eliminated throughout the zoom range for notable clarity and color accuracy.
- ARNEO and Nano Crystal Coats are used to prevent ghosting, reflections, and flare in order to realize improved contrast and clarity when working in strong lighting and backlit conditions. The Nano Crystal Coat controls incidental light from a diagonal direction while the ARNEO Coat controls incidental light from a vertical direction.
- Multi-focus system incorporates two separate AF drive units, which are synchronized, to deliver especially fast and accurate focusing throughout the zoom range. This system uses stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications.
- Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.
- Minimum focusing distance of 2.5', along with a maximum magnification of 0.38x, benefits working with close-up subjects.
- Vibration Reduction image stabilization helps to reduce the appearance of camera shake by approximately 5.5 stops to better enable handheld shooting in low-light situations.
- Short zoom throw rotation of just 80° permits quick changing between the 100mm to the 400mm positions.
- Updated zoom design prevents lens creep, regardless if the lens is pointing straight up or down, without having to adjust torque or tension settings.
- Programmable Control Ring is, by default, set to adjust manual focus, but can also be used to control aperture or exposure compensation.
- Integrated OLED lens information panel allows you to quickly confirm aperture setting, focus distance, and depth of field figures right on the lens in both bright and dark situations.
- Two assignable L.Fn buttons work in conjunction with camera-based Fn buttons to provide seamless points for quickly changing exposure settings and other functions.
- Dust- and moisture-resistant lens barrel, along with a front fluorine coating, benefits the lens' use in inclement conditions.
- Inner Balance technology helps maintain a consistent center of gravity when shifting the zoom position, offering greater stability when tracking moving subjects using a gimbal head.
- Rotating tripod collar offers mounting stability when shooting atop a monopod or tripod.
- Compatible with optional Z-Teleconverter TC-1.4x and TC-2x to further extend the reach of this lens.
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. 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.
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.
