Advanced Optical Design
Six "F" Low Dispersion (FLD), two Special Low Dispersion (SLD) elements, and five aspherical elements reduce chromatic aberration and color fringing across the zoom range, improving clarity and color accuracy. In addition to superior optical performance, the five aspherical elements contribute to the lens's compact structure with their thin and highly polarized design. The fast f/2.8 aperture and rounded 11-blade diaphragm create a large, beautiful bokeh effect. Multi-layer anti-reflective and protective nano coatings have been applied to the lens elements to minimize flare and ghosting, resulting in contrast-rich and color-neutral images, even in backlit conditions. The lens is designed to reduce focus shift as the angle of view changes across the zoom range, ensuring natural focus transitions during video recording.
A high-response actuator linear motor (HLA) provides focusing speeds more than three times faster than its predecessor. In wide-angle mode, the minimum focusing distance has been improved to 17 cm with a maximum magnification of 1:2.7, making it suitable for close-up photography or working in confined spaces.
Despite having the same number of lens elements, the overall length of the lens has been shortened to 12.2 cm compared to the previous model, and the weight has been reduced to 725 g. The aperture ring features both click and lockable settings for improved handling during use. The sturdy internal structure includes metal parts for the zoom mechanism, while the exterior is equipped with rubber seals at the mount to protect the lens from dust and moisture. Two integrated AF-L buttons can be programmed to adjust various settings, and the lens also includes a dedicated AF/MF switch and a zoom lock button to prevent accidental extension of the lens barrel.
