Leica DG Summilux 12mm f/1.4 ASPH. Lens with UV Filter Kit Overview

More than just the lens, the Panasonic Leica DG Summilux 12mm f/1.4 ASPH. Lens with UV Filter Kit from B&H bundles the wide-angle 24mm-equivalent prime with a 62mm UV filter.

Panasonic Leica DG Summilux 12mm f/1.4 ASPH. Lens

A fast and optically refined wide-angle prime, the Leica DG Summilux 12mm f/1.4 ASPH. Lens from Panasonic is a 24mm equivalent lens designed for Micro Four Thirds digital cameras. Characterized by its truly bright f/1.4 maximum aperture, this lens is ideal for working in low-light conditions and also affords a wealth of control over focus placement for using shallow depth of field techniques. The optical design employs a pair of aspherical elements, two ultra extra-low dispersion elements, and one extra-low dispersion element in order to control both spherical and chromatic aberrations for a high degree of sharpness and clarity from edge to edge. Benefitting the optical assets, this lens also incorporates a smooth and quiet autofocus motor that is well-suited to both stills and video recording, and a manual AF/MF switch lends direct focus mode adjustment for more intuitive handling. Additionally, the all-metal construction of the lens is also weather-resistant in order to permit working in trying environmental conditions. Pairing Leica's design legacy with Panasonic's technological innovation, this versatile wide-angle prime is distinguished by both its optical merits as well as intuitive handling and contemporary functionality.

Designed for mirrorless Micro Four Thirds digital cameras, this wide-angle 12mm f/1.4 lens provides a 24mm equivalent focal length.
The bright f/1.4 maximum aperture is well-suited to working in difficult and low lighting conditions, and also affords greater control over depth of field for selective focus techniques.
Two aspherical elements are featured in the lens' design, which help to maintain a compact form factor as well as help to reduce spherical aberrations and distortions.
Two ultra extra-low dispersion (UED) elements and one extra-low dispersion (ED) element work to significantly minimize color fringing and chromatic aberrations for increased clarity and color fidelity.
The smooth and near-silent autofocus performance complements movie recording applications while the quick operation is beneficial to still photographers.
A manual aperture ring gives tactile control over exposure settings and a dedicated AF/MF switch offers a simple, intuitive means for switching between focusing modes.
The metal construction of the lens is durable as well as splash- and dust-resistant when paired with Lumix Micro Four Thirds cameras for working in harsh environments.
A rounded nine-blade diaphragm contributes to a pleasing bokeh quality when making shallow depth of field imagery.

Chiaro Pro 62mm 98-UVATS UV Filter

The Pro 62mm 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.

98% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished optical glass and advanced coatings, Chiaro offers a 98% transmission rate, which is an excellent 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 allow 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 Optical Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is highly-polished for flatness that ensures excellent 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.
UV Protection
The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
Hard Anodized Aluminum Construction
The process of hard anodizing toughens and strengthens the aluminum for a lightweight yet durable filter ring.
Slim Design
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 to better grip the filter when you're attaching and removing it, or when you're stacking filters.
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.

How well does this lens work for astrophotography?
Asked by: Jerry
It's as good as it gets in MFT format. I still wish it had a wider field of view, but so hard with the crop sensor. But the light sensitivity is awesome--super detailed milky way shots. In fact, for a star trail photo, I usually have to dampen the details to highlight just the brightest stars.
