Samyang Optics is releasing the MF 135mm, a representative telephoto lens that has been loved for its excellent resolution since its launch in 2015, as an AF lens to commemorate the 50th anniversary of its release. Typically, MF 135mm F2 lens has been loved as a lens for portrait photography thanks to its beautiful background expression, but over time, the MF 135mm went beyond portrait photography and became more popular for landscape and astrophotography with superb resolution at a bright maximum aperture. Introducing the Samyang Telephoto AF 135mm F1.8 FE, equipped with outstanding optical performance that has been recognized for over 50 years, AF performance that has been steadily evolving, and convenience features.

1. Superb resolution and light in weight with the newly designed optical system
2. Ultra-precision Aspherical lens offering a soft and beautiful bokeh
3. Focus Range Limiter useful for shooting portraits and close-ups
4. Optimized function for astrophotography - Astro-Focus Mode and LED index

Superb Resolution in Lightweight 135mm

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!

Amazing Performance from Samyang's Advanced Optical Design

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.

Gorgeous Bokeh

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!

Short Minimum Focusing Distance

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.

Advanced Fast and Quiet AF for Stills and Movies

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.

Customized Buttons to Maximize the Operability and Reliability

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.

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.

Modern Design & Weather Sealing

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.
