The Fujifilm GF 55mm F1.7 R WR Lens is a large-aperture prime lens with the standard focal length of 55mm (equivalent to 44mm in the 35mm film format). The Large Format's enriched descriptive capability is combined with the creamy bokeh characteristic of the large maximum aperture, making the main subject stand out against blurred background.
The lens' focal length gives the field of view close to that of human vision to create a natural perspective. This makes it ideal for information dense snapshots to capture how the main subject relates to the background, as well as portraiture with a tack-sharp subject against beautiful bokeh.
