The XF56mm F1.2 R APD lens is a standard prime lens with a focal length equivalent to 85mm*1. The lens has a maximum aperture of F1.2 making it the world's brightest autofocus lens for digital cameras with an APS-C sensor. In addition, the new apodizing filter makes it the perfect choice for portraits, with every strand of hair visible and a unique bokeh effect. The built-in APD filter, the pinnacle of Fujifilm's nanotechnology, produces smoother bokeh, making the subject stand out distinctly from the background, and enhances creativity for portraits and a wide range of other subjects. When attached to an X Series camera body, the XF56mm F1.2 R APD lens weighs about half*2 as much as a DSLR camera with a lens of the same focal length and F value. Plus it's quick to use thanks to the high-speed, quiet autofocus.
