Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 ASPH. Lens

A unique lens with a distinctly bright design, the Leica DG Vario-Summilux 10-25mm f/1.7 ASPH. from Panasonic is a 20-50mm-equivalent zoom for Micro Four Thirds mirrorless cameras. The impressively fast f/1.7 constant maximum aperture enables improved depth of field control and low-light shooting capabilities throughout the zoom range. Balancing the impressive f/1.7 performance, the optical design incorporates a series of low dispersion, aspherical, and high refractive index elements, which help to greatly reduce chromatic and spherical aberrations for improved clarity and sharpness. Complementing the optics, this lens is also characterized by its durable, weather-sealed physical design, along with a fast autofocus system, versatile focusing clutch design, and a stepless, de-clicked aperture ring to suit video applications.

Wide-to-normal zoom is designed for Micro Four Thirds mirrorless cameras and offers a 20-50mm equivalent focal length range. Impressively bright f/1,7 constant maximum aperture excels in low-light conditions throughout the zoom range and also offers improved depth of field control. Three aspherical elements, four extra-low dispersion elements, and one ultra high-refractive index element all combine to suppress color fringing, chromatic aberrations, and spherical aberrations for high clarity, sharpness, and color accuracy. Fast 240 fps autofocus drive, along with an internal focusing system, delivers smooth, accurate, and quiet focusing performance to benefit both stills and video applications. Additionally, a focus clutch mechanism delivers especially quick AF/MF switching. Physical aperture ring has a stepless, de-clicked design for smooth, silent aperture switching to benefit video applications. Splash, dust, and freezeproof design benefits working in inclement weather conditions. Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. UPC: 885170366572 Chiaro Pro 77mm 99-UVBT UV Filter

The  Pro 77mm 99-UVBT 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.

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. Resistance Coating 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 Multi-coating enhances light transmission to the demanding level we set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images. UV Protection The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes. Brass Construction 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. 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. UPC: 847628593336
