The constant design f/2.8 maintains constant performance across the entire zoom range and also benefits from performance under poor lighting conditions and control of depth of field.
The bright design and ultra wide-angle focal length make this lens suitable for astrophotography needs.
The wide range of zoom adapts to everyday travel and shooting needs and is particularly suitable for urban landscapes, landscapes, interiors and architectural subjects.
The 9-lamelle rounded diaphragm contributes to a pleasant quality of the bokeh, to the advantage of the use of reduced depth of field and selective focus techniques.
Two very low-dispersion elements help to correct color aberrations and color fringes for a clean and clear color rendering.
A Super ED element is also used, which offers even lower dispersion properties and further reduces color fringes and various other chromatic aberrations.
Three aspherical elements reduce spherical aberration and distortion to make sharp images with accurate rendering. In addition, these specialized elements also promote a more compact and lightweight lens design.
