Podrobný popis

The Laowa 25mm f/2.8 is a compact ultra macro lens created for extreme close-ups. The up to 5x magnification it offers makes it possible to photograph miniature subjects. The optical system of the Laowa 25 mm f/2.8 Ultra Macro consists of 8 elements arranged in 6 groups. Among the lenses is an ultra-low dispersion glass element, which is responsible for reducing chromatic aberration. The entire construction provides images with high sharpness and faithful colour rendering. The f/2.8 - f/16 adjustable aperture and relatively short focal length for this type of lens provide a comfortable depth of field. The variable magnification scale (2.5x - 5x) is perfect for photographing subjects of different sizes, such as insects, plants or details of larger objects. The lens cannot be used for applications other than macro photography. The lens barrel is made entirely of metal. A mount, available from a separate sale, allows the lens to be quickly mounted on a tripod, and an integrated plate in the Arca-Swiss standard (38 mm) ensures wide compatibility with photographic heads.
