Key Features:
- Wide-to-normal zoom is designed for Micro Four Thirds mirrorless cameras and offers a 20-50mm equivalent focal length range.
- Impressively bright f/1,7 constant maximum aperture excels in low-light conditions throughout the zoom range and also offers improved depth of field control.
- Three aspherical elements, four extra-low dispersion elements, and one ultra high-refractive index element all combine to suppress colour fringing, chromatic aberrations, and spherical aberrations for high clarity, sharpness, and colour accuracy.
- Fast 240 fps autofocus drive, along with an internal focusing system, delivers smooth, accurate, and quiet focusing performance to benefit both stills and video applications. Additionally, a focus clutch mechanism delivers especially quick AF/MF switching.
- Physical aperture ring has a stepless, de-clicked design for smooth, silent aperture switching to benefit video applications.
- Splash, dust, and freezeproof design benefits working in inclement weather conditions.
- Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
