Sony FE 50mm f/1.4 GM Lens

FE 50mm F1.4 GM Sony Alpha E-mount Full-frame Large-aperture Prime G Master Lens for stills and movies with excellent G Master resolution and bokeh in a compact, lightweight design.

Breathtaking G Master TM image quality right out to the edges of the frame.

Two high-precision XA (extreme aspherical) lens elements effectively correct distortion and most types of aberration. This new optical design also employs an ED (extra-low dispersion) glass element to suppress chromatic aberration. And with our original Nano AR Coating II on lens surfaces, internal reflections that can cause flare and ghosting are dramatically reduced.

Innovative optics and a large F1.4 aperture deliver magnificent bokeh

Innovative optics and a large F1.4 maximum aperture combine to deliver magnificent bokeh. Smooth, naturally defocused background and foreground bokeh are ideal for making portrait subjects stand out from their surroundings. Advanced features that contribute to superb bokeh quality include XA (extreme aspherical) elements that reduce onion-ring bokeh, and carefully controlled spherical aberration during design and manufacture.

Fast, precise, quiet AF and tracking for stills and movies

The lens’s focus group is driven by high-thrust XD (extreme dynamic) linear motors and an advanced control algorithm for smooth, responsive focus drive. Noise and vibration are minimized for refined, quiet AF operation that can be a huge advantage when shooting movies. Movie subjects are smoothly captured and tracked even when shooting at 120 fps or other high frame rates. The breathing compensation function in compatible α series cameras is also supported

Circular aperture with 11-blade iris for naturally rendered bokeh

The deep, soft bokeh available with full-frame image sensors is further enhanced by a 11-blade circular aperture and optimally controlled spherical aberration. All of this supports the creation of impressive, memorable imagery.

Dedicated aperture ring, click/de-click and iris lock switches

An aperture ring provides direct, rapid control. The aperture ring click stops can be turned ON to provide tactile feedback when shooting stills, or OFF for smooth, silent control when shooting movies. There is also an iris lock switch that prevents the aperture ring from being accidentally moved between the [A] and F1.4 ~ F16 settings

Customizable focus hold buttons

Two customizable focus hold buttons are provided for easy access and control at most any orientation. Several alternative functions can be assigned from the camera’s menu.

Front 67mm threaded for screw-on filters

Front 67mm threaded for screw-on filters This lens accepts standard 67 mm screw-on filters. Thanks to its internal focus system the front element does not rotate while focusing, facilitating the use of circular polarizing filters for landscape photography or variable ND filters for movies. The FE 24mm F1.4 GM and FE 35mm F1.4 GM lenses are also threaded for 67 mm filters, so filters can be shared.
