Covering a versatile and popular range of focal lengths, the Lumix S PRO 70-200mm f/4 O.I.S. from Panasonic is an L-mount telephoto zoom featuring an f/4 constant maximum aperture. A sophisticated optical design is employed, which incorporates a series of aspherical, low dispersion, and high refractive index elements, to control a variety of aberrations, color fringing, and distortion for sharp, clear, well-corrected imagery throughout the zoom range. Complementing the optics is a unique double focus system, which utilizes both a linear motor and a stepping motor, to provide especially fast and precise focusing performance. Additionally, an Optical Image Stabilizer reduces the effects of camera shake for sharper handheld shooting and the lens sports a weather-sealed design for use in harsh conditions.
The Pro 77mm 99-UVBTS Brass UV Filter is Chiaro’s top-performing protective UV filter offering 99% 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 superior 99% light transmission, Chiaro uses highly-polished Schott 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. The durable brass filter ring is designed to screw on and off effortlessly, and it’s thin to prevent vignetting when used with wide-angle lenses. Side knurling is crafted to help ensure 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.
