Complementing the lens itself, the Panasonic Lumix S PRO 16-35mm f/4 Lens with UV Filter Kit from B&H bundles the wide-angle zoom with a 77mm UV filter.
Panasonic Lumix S PRO 16-35mm f/4 Lens
A staple of wide-angle versatility, the Lumix S PRO 16-35mm f/4 from Panasonic is an L-mount wide zoom featuring an f/4 constant maximum aperture. An optimized optical design 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-magnet linear motor focus system, which provides high-speed response and power while remaining compact in size. The lens also sports a rounded nine-blade diaphragm, which contributes to the quality of bokeh, and a weather-sealed construction to suit working in a variety of weather conditions.
Wide-angle zoom is designed for full-frame L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 24-52.5mm equivalent focal length range.
Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range.
Three aspherical elements and one ultra-high refractive index element help to minimize distortions and spherical aberrations throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.
One extra-low dispersion element greatly reduces chromatic aberrations and color fringing in order to produce a high degree of clarity and color accuracy.
The autofocus focus system employs both a double-magnet linear motor to deliver impressively fast and precise focusing performance while remaining compact. A focus clutch mechanism has also been incorporated, which allows for near-instant AF/MF switching.
Splash, dust, and freezeproof design benefits working in inclement weather conditions down to -14°F.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Chiaro Pro 77mm 99-UVBTS Brass UV Filter
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.
99% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished Schott glass and advanced coatings, Chiaro can offer a 99% transmission rate, which is the highest possible 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 Schott Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The Schott glass in this Chiaro filter is highly-polished for flatness that ensures superior 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.
The durable brass filter ring offers a substantial, premium feel. The unique properties of brass minimize the chance of jamming or binding when you're screwing the filter onto your lens or stacking filters.
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.
