Sleek and Speedy Versatility A surprising combination of compactness, speed, and versatility, the Leica Vario-Elmarit-SL 28-70mm f/2.8 ASPH. is a sleek standard zoom for L-mount mirrorless cameras. Trading a bit of reach on the wide end of the zoom, compared to a conventional 24-70mm lens, this zoom instead manages to be especially small and lightweight while still offering a constant f/2.8 maximum aperture for excellent low-light performance and depth of field control. This portable zoom is ideal for everyday shooting and a range of subjects, including everything from landscapes, to portraits, to travel scenes. Compact Performance Designed as the most compact and lightweight standard zoom for the SL system, this lens covers a useful wide-angle to portrait-length range and retains an impressively bright f/2.8 constant maximum aperture. Constant f/2.8 maximum aperture enables working in low-light conditions throughout the zoom range as well as benefits control over depth of field. Optical design uses a trio of aspherical elements to improve sharpness and promote the more compact, portable lens design. Updated lens coatings offer increased contrast and accurate color rendering in a variety of lighting conditions. Durable Design and Intuitive Handling In addition to its portable design, this lens is also built for use in a variety of conditions and sports a reliable physical construction. Portable lens weighs 1.3 lb and measures 2.9 x 4"; this is more than an 8 oz weight savings compared to the Vario-Elmarit-SL 24-70mm f/2.8 lens while also being nearly an inch shorter. Lens housing is built from magnesium and aluminum alloys and has a simple, minimalist design with dual control rings to adjust both focus and zoom positions. Dust- and splash-proof design for working in inclement conditions and an Aqua-Dura hydrophobic coating has been applied to the front and rear elements.
