Developed to provide the most ideal focal range for normal use—covering frequently-used focal lengths between 18mm & 135mm—the 18-135mm mid-range zoom lens enables rich expression for a wide range of shots. Direct Manual Focus (DMF) means that you can switch between AF & MF without removing your eyes from the viewfinder to seize fleeting photo ops with ease. Plus, enjoy smooth & quiet AF thanks to the Smooth Autofocus Motor (SAM), which also improves AF response when shooting moving subjects. & with a single ED glass lens element as well as a pair of Aspherical lens elements, the lens delivers images with low levels of colour aberration for excellent image quality in any setting.
