The Sony FE 50mm f/1.4 GM Lens is designed with sophisticated elements and advanced optics to provide uncompromising image quality for still and video shooters alike. An excellent choice for everyday use, this lens also includes a fast and precise autofocus system in a lightweight and compact design making it convenient to take with you everywhere you go. Two XA (extreme aspherical) elements minimize aberrations and distortions while also providing outstanding resolution and sharpness. One ED (extra-low dispersion) glass element effectively eliminates chromatic aberration and color fringing to produce a high degree of clarity and color accuracy. Bright f/1.4 maximum aperture provides a very shallow depth of field for pleasing background blur when using selective focus techniques. Ideal for portraits, a circular 11-blade aperture produces deep and dreamy bokeh. The lens's f/1.4 aperture also allows for handheld shooting in low-light conditions. Designed to enhance control for both still and movies, this design also provides natural manual focus control when desired. Internal focusing design offers more responsive focusing performance and maintains a consistent overall lens length during operation. 

New for Sony primes, an iris lock switch prevents the aperture ring from being accidentally moved. This switch can also be unlocked allowing the aperture ring to rotate seamlessly and silently. An easy-to-read aperture ring with f-stop engraving can be quickly de-clicked on the lens barrel for smooth and silent aperture control. Two focus hold buttons are featured on the lens barrel for intuitive control and rapid access to select settings. Its wide f/1.4 maximum aperture, complex optical design, and inclusion of a high-performance AF system. This lens still manages to be compact and lightweight for everyday use, measuring 3.1 x 3.7" and weighing just 18 oz. Fluorine coating on the front element repels water, oil, fingerprints, and contaminates while also making the lens easy to clean.
