Features 10 elements from 6 groups Metal exterior gives a sense of premium quality and robustness Inner-focus AF system uses a stepping motor Weather and dust resistant and can operate in temperatures as low as -10°C The Fuji X Lens XF23mm F2 R is sealed to make it weather and dust resistant and it is capable of operating at temperatures as low as 10degC. When mounted on the weather and dust-resistant mirrorless digital cameras, it allows you to shoot in light rain or a dusty environment with peace of mind. Advanced image quality The lens consists of 10 elements from 6 groups, including 2 aspherical elements. The optimum positioning of the aspherical elements ensures flatness of the image plane for edge-to-edge sharpness. The aspherical elements are used as part of the focussing group to minimise performance fluctuations between different focal distances. Compact, lightweight and stylish design The compact and stylish form factor almost eliminates mechanical vignetting when using the optical viewfinder on the cameras. The aperture ring and focus ring have just the right amount of clicking and torque for great operability. Fast and silent autofocus The inner-focus AF system uses a stepping motor to drive lightweight focusing elements for silent and fast autofocus. When combined with the phase-detection AF system, the lens can focus in an astonishing 0.05 seconds.
