The FUJIFILM XF 150-600mm f/5.6-8 R LM OIS WR strikes a unique balance between immense reach and a relatively portable design, making for an ideal lens to capture the most remote and distant adventures. Quick and reliable autofocus performance thanks to a linear motor system, which also enables smooth and silent focusing performance that benefits both stills and video applications. This focusing system also helps to greatly reduce focus breathing. On-lens focusing controls for immediate, tactile adjustment over focusing settings: focus range limiter switch, AF-ON, and AF-L buttons.  Modest f/5.6-8 maximum aperture helps maintain a relatively portable form factor, meaning this lens can be used handheld and packed for easier use on location and for subjects that don't require the utmost speed. The rounded nine-blade diaphragm contributes to a smooth, circular bokeh quality when using shallow depth of field and selective focus effects. Front fluorine coating protects against water, grease, dirt, and smudging, and also makes it easier to clean the front element.
