Offering a versatile wide-angle to portrait-length range, the Vario-Elmarit-SL 24-90mm f/2.8-4 ASPH. is a fast standard zoom from Leica designed for full-frame L mount mirrorless cameras. The 18 elements in 15 groups lens construction incorporates four aspherical elements and 11 anomalous partial dispersion elements, which help to reduce chromatic aberrations and distortions throughout the zoom range for notable image sharpness and clarity. The f/2.8-4 maximum aperture benefits working in a variety of lighting conditions and also offers greater control over focus position for working with shallow depth of field techniques. Designed for consistent performance at all focal lengths and focusing distances, the versatility this lens affords is well-suited to nearly any photographic application. Complementing the imaging performance is an apt 3.5-stop effective Optical Image Stabilization system that minimizes the appearance of camera shake for sharper handheld shooting in difficult lighting conditions. A silent and precise autofocus motor also benefits both stills and video capture, and utilizes an internal focusing mechanism to quicken overall performance. This focusing design also prevents the front 82mm filter ring from rotating during use to better enable the use of circular polarizing or graduated filters. Additionally, this lens features Leica's AquaDura hydrophobic coating on the front and rear elements, to guard against moisture and smudging, and a fully dust and water-sealed design to protect the lens during use in inclement environments.
