A bright, normal-length lens, the Leica DG Summilux 25mm f/1.4 II ASPH. from Panasonic is a 50mm equivalent prime for Micro Four Thirds mirrorless cameras. Characterized by its fast f/1.4 maximum aperture, this lens affords notable control over depth of field and is also well-suited to working in low-light conditions. Its optical design incorporates one UHR element and a pair of aspherical elements to reduce spherical aberrations and distortion, and a Nano Surface Coating has also been applied to suppress lens flare and ghosting for greater contrast in harsh lighting. A stepping autofocus motor, along with an internal focus design, contributes to quick and quiet focusing performance for both photo and video applications. Additionally, this lens sports a dust- and splash-resistant construction to benefit working in inclement conditions.
This Lens Cleaning Kit from ZEISS is a complete solution for cleaning valuable optics such as camera lenses, eyeglasses, telescopes, or spotting scopes.
Both wet and dry cleaning tools are provided. For blowing dust off an optical surface, the air blaster can be used, while the retractable lipstick-style cleaning brush can dislodge more stubborn dirt or dust particles.
When a thorough wet cleaning is required, a 1 oz bottle of cleaning fluid or ten, individually-wrapped pre-moistened lens wipes are available. Designed for single use, these wipes come in individual, disposable packets. They can be stored in a camera bag, glove compartment, studio, or lens case for whenever they may be needed.
The non-abrasive, 7.1 x 7.1" microfiber cloth can be used after applying fluid or one of the pre-moistened wipes in order to complete the cleaning process and ensure that no streaks or spots remain. It can also be used on its own to effectively remove smudges.
A fabric travel case is also included to hold the contents of the entire kit.
