The high-quality Fujinon XF 16-55 mm F2.8 R LM WR lens has a lens construction that consists of 17 elements in 12 groups. Fujifilm used three aspherical elements and three 'extra low dispersion' elements. The special coating Nano-GI (Gradient Index) is developed by Fujifilm to avoid optimally flare and ghosting. This weather-resistant lens with a constant aperture of F2.8 throughout the zoom range delivers very sharp images from corner to corner. The Fujinon XF16-55 mm is also powered by a linear motor, which makes that you can shoot very comfortably with fast and quiet autofocus.
