Specification :
Not only outstanding resolution but also weight is important when shooting portraits. Especially in a handheld shooting environment, the benefit of the lightweight lens is huge, so innovative technology was needed to combine resolution and weight at the same time. The Samyang AF 135mm F1.8 FE is lighter than other 135mm lenses compatible with full-frame Sony FE mount, but it realizes overwhelming resolution in the entire image area and expresses the subject with clear image quality. You can capture the subject's details from the fluttering hairs of models to the twinkling of nebulae light-years away with unprecedented resolution!
An optimum resolution is achieved through the optical design of 6 special glasses(3 ED, 2 HR, and 1 U-ASP) among 13 elements in 11 groups. Three extra low-dispersion lenses (ED) produce clear image quality effectively controlling chromatic aberration. Equipped with two high refractive lenses (HR) with excellent refractive index and an ultra-precision aspherical lens (UA), deliver excellent sharpness and contrast in all areas of the image.
The AF 135mm F1.8 FE uses a large-diameter aperture to provide smooth background blur. It effectively separates the subject from the background, using a shallow depth of field. Also, it is equipped with UA(Ultra-precision Aspherical) lens, so you can enjoy the natural and refined bokeh. Using this smooth bokeh, you can freely create your images highlighting your subject!
Although it is a 135mm telephoto lens that effectively controls aberration at all focusing distances has made it possible to achieve a minimum focus distance of just 0.69 meters (2.26 ft) and a maximum magnification of 0.243x for close-up photography. Small accessories and other subjects can be captured with remarkable resolution and soft, beautiful background bokeh.
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.
The AF 135mm F1.8 FE features 3 different customized buttons such as Focus Hold Button, Custom Switch, and Focus Range Limiter Switch to enhance usability.
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.
Focus Range Limiter Switch
The Focus Range Limiter only operates in AF mode.
• It is useful when the distance from an object has been determined.
• Move the Focus Range Limiter forward or backward to select the focus range.
- FULL: The AF range is set to infinity at a minimum focus distance of 0.69m.
?(AF search may take slightly longer.)
- 0.69m - 2m: The AF range is set between 0.69m and 2m, which is suitable for close-up shooting.
- 1.5m - ∞: The AF range is set from 1.5m to infinity, which is suitable for normal shooting.
The AF 135mm F1.8 FE has been developed and enhanced, taking into consideration not only the design features but also the user's shooting environment. It has a micro-patterned rubber focus ring, which feels great to operate and the weather-sealing protects the lens from light rain, snow, and dust. You can easily tell the Astro-Focus Mode status with the LED Index when shooting at night.
