Specification :
The AF 50mm F1.4 FE II is the smallest (88.9mm/3.5in length) and lightest (420g/14.8oz weight) among all the large-aperture standard 50mm focal length lenses compatible with the Sony FE mount, so it's even a perfect match to compact Sony mirrorless cameras with a gimbal.
Optimum resolution is achieved through the 6 special glasses(2 U-ASP, 3 HR, and 1 ED) among the optical design of 11 elements in 8 groups. Combined with Sony's full-frame image sensor, this lens delivers superior sharpness and contrast in all areas of the image.
The AF 50mm F1.4 FE II uses a large-diameter aperture to provide smooth background blur. It effectively separates the subject from the background, using a shallow depth of field and adding drama to the scene. Also, it is equipped with UA(Ultra-precision Aspherical) lenses, so you can enjoy the natural and refined bokeh. Using this smooth bokeh, you can freely create photos highlighting your subject!
Tracking the subject accurately and quickly, the AF also operates quietly and smoothly when shooting video. Samyang's Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the focusing lens groups.
The optical design minimizes focus breathing, which is especially advantageous for video recording. There is almost no change in the angle of view when adjusting the focus from close focus to infinity, so you can experience professional cinematic effects during shooting video with the subject moving forward or backward, or focusing from the front or back.
Focus Hold Button
Pressing this button on the lens will keep the lens locked to that focusing distance. You can assign functions such as Eye AF in settings on the camera body.
Custom Switch
There is a custom switch, which can be set to allow adjustment of the aperture silently by rotating the focus ring. Using the optional Lens Station, you can set up the mode to suit your own preference*.
* More functions will be added through firmware updates in the future.
The minimum focusing distance is just 0.40m (1.31ft), so it is versatile and possible to produce a unique perspective close to the subject. This makes it easier to take close-up and dramatic shots of food, portraits, and nature.
The usability of the AF 50mm F1.4 FE II lens has been developed and enhanced, taking into consideration not only the design but also the user's shooting environment. It has a micro-patterned rubber focus ring, so feels great to operate and weather-sealing also protects the lens from light rain, snow, and dust. The matte finish and the subtle red ring (dependent on viewing angle) give it a modern feel.
