Sony SEL 10-18mm f/4.0 OSS ultra-wide-angle lens is designed for APS-C Sony E-mount cameras. Optical SteadyShot (OSS) image stabilization supports handheld photo and video shooting. A 7-blade circular diaphragm provides more natural, rounded defocus and bokeh. Aspherical elements reduce distortion, and Super ED (extra-low dispersion) glass delivers high contrast and resolution even at 10 mm. Internal focusing keeps the barrel from extending, making the lens more compact, improving autofocus response, and reducing minimum focusing distance. Included: Sony SEL 10-18mm f/4.0 lens, front cap, rear cap, lens hood, UV filter, transport pouch.
