Ultra wide-angle 9mm f/2.8 prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides a 13.5mm equivalent focal length.
Bright f/2.8 maximum aperture is well-suited to working in low and difficult lighting conditions.
Rectilinear design renders subjects with minimal distortion in order to suit landscape and architectural applications.
Three extra-low dispersion elements reduce chromatic aberrations and color fringing for increased clarity and color neutrality. Two aspherical elements are also featured to limit spherical aberrations for improved sharpness.
A Frog Eye Coating has been applied to repel both dust and moisture for added protection when working in inclement conditions.
Manual focus design offers a minimum focusing distance of 4.7″.
Built-in petal-shaped lens hood shields the lens from stray light to reduce flare and ghosting and also protects the front elements from accidental impacts.
