Fujifilm XF 1655mm f/2.8 LM WR | Wide Zoom LensThe weatherresistant zoom lens XF1655mm F2.8 R LM WR is a flagship "XF standard zoom lens" with a focal length equivalent to 24mm* to 84mm*, and a constant F2.8 aperture throughout the range. The advanced optical design controls various forms of aberration to achieve edgetoedge sharpness across the entire zoom range.Optically designed to draw out the maximum image quality as a flagship standard zoom lensIn order to achieve the bestinclass image quality, the fast standard zoom lens with a constant aperture of F2.8 consists of 17 elements in 12 groups. This includes three aspherical lens elements to control spherical aberration and distortion, and three ED glass lens elements to reduce lateral chromatic aberration (wideangle) and axial chromatic aberration (telephoto), thereby achieving edgetoedge sharpness across the entire zoom range. Nine rounded aperture blades create a smooth, circular bokeh. The suppression of spherical aberration to the ultimate extent contributes to produce beautiful bokeh at both the front and backHighspeed, quiet auto focus thanks to the Linear MotorBy reducing the weight of the focus lens and mounting the Twin Linear Motor, highspeed, quiet AF is possible. The fastest AF speed of 0.06 seconds brings comfort to your photoshoot when by combining this lens with an X Series camera body* offering Phase Detection AF. Combined with the nearsilent shutter sound, photos can be taken unnoticed in quiet locations.
