The 35mm f/1.8 OSS Alpha E-mount Prime Lens from Sony is a sharp, prime lens for Sony E-mount cameras with an APS-C sensor size. It is a compact, fixed focal length lens which is equivalent to 52.5mm in 35mm. A fast maximum aperture of f/1.8 means the lens is ideal for blur-free capture of fast moving subjects and for retaining crisp imaging in low light. A quiet linear motor controls focus while an in-lens stepping motor controls aperture, together they offer smooth and virtually silent lens action, which is ideal for shooting video. Direct Manual Focus is also featured which allows for fine manual focus control and is operable even in autofocus mode. Sony's built-in Optical Image Stabilization system provides approximately 4-stops worth of shake control, making the lens even more functional in low light conditions and great when tracking moving subjects in video.

Improved optics have reduced spherical aberration and provide uniform contrast across the sensor and sharp images even when shooting wide-open at f/1.8 aperture. The circular aperture helps to create smooth and circular bokeh.
