The feature set and overall performance of the Samyang 12mm F2.0 AF Compact Ultra Wide Angle lens for APS-C Fuji X mount cameras are unmatched by any in its class.

At 7.51oz in weight, 2.33” in length, this compact, rugged, yet lightweight autofocusing lens offers the best combination of value and performance than ever before. What’s more, it provides a rectilinear 99.1°angle of view, and with the added protection of weather sealing, and a Rear Protector Glass, it allows for lots more versatility.

Utilizing the newest Linear Stepping Motor technology, the Samyang 12mm F2.0 AF lens combines a more compact design with improved auto-focus performance. By requiring the movement of only a single focusing group, it delivers especially fast, quiet, and precise focusing, whether shooting stills or videos. The design also allows for close focusing to 7.48” with no change in length or front element rotation.

With a bright F2.0 aperture, faster shutter speeds can be achieved for superior astrophotography and low light results. Furthermore, the F2.0 aperture can help create an impressive sense of depth to your daytime images by effectively separating the subject from a pleasing, de-focused background.

The optical construction is comprised of twelve elements in ten groups with a new and further advanced version of Ultra Multi Coating (UMC). Besides controlling flare and ghosting, this improved UMC maximizes light transmission, contrast and color accuracy. Thanks to five specialized lens elements (1 Aspherical, 3 Extra-low Dispersion, and 1 Hybrid-Aspherical) aberrations and distortion are minimized to produce sharp, thoroughly corrected imagery.

The Samyang 12mm F2.0 AF incorporates a new elegant look with a matte black finish and comfortable micro pattern rubber focusing ring over a durable all-metal housing. And, with its dramatically wide angle of view, this Samyang exciting and attractively priced high-performance model is the lens of choice for landscape, night sky, architecture and interior shooting.

The Samyang 12mm F2.0 AF Lens for Fuji X mount comes packed with a removable petal-shaped hood, lens caps, and a custom fitted case.

The Samyang AF 12mm F2 FX is optimized for Fujifilm cameras featuring the X-Trans sensor, in order to provide stable AF performance. You can check the 'Camera Compatibility List' below.

Optical Construction


Wide-Angle Captures the Rich Colors of Fujifilm

The AF 12mm F2 X is a dream lens for shooting magnificent landscapes that go beyond the normal viewing angle, built with Samyang's optical design technology, advanced AF technology, and convenient functions. This 12mm focal length lens provides an ultra-wide-angle of view of 99.1° on the Fujifilm X mirrorless cameras. Now Fujifilm X photographers can create wide-angle landscapes and snapshots with the background landscape by taking advantage of wide angle of view.

Excellent Resolution in All Areas of the Image

You can take outstanding image quality landscapes and cityscapes with decreased optics aberrations thanks to the advanced optical design, incorporating 5 special glasses (1 H-ASP, 1 ASP, and 3 ED). This lens achieves exceptional resolution image quality from the center to the edges of the frame, even at F2 maximum aperture. The backlight haze is effectively decreased due to the 14-layer-special coating even with the small hood.

Impressive Background Blur and Bokeh with Bright F2 Aperture

The AF 12mm F2 X lens uses a large-diameter aperture to provide smooth background blur. It effectively separates the subject and the background using a shallow depth of field to capture a unique image of an ultra-wide-angle in which the background is compressed. The 7-blades produce smooth and natural bokeh and impressive starburst effect.

Compact & Lightweight with New Modern Design

The AF 12mm F2 X lens has a length of 59.2mm (2.3in) and weighs just 212g (7.5oz), so it's a perfect match to compact Fujifilm X-Series cameras with a gimbal. The matte finish and the subtle red ring (dependent on viewing angle) give it a modern feel. Usability has been enhanced by considering not only the design but also the users’ shooting environment. There is a micro-patterned rubber focus ring, so it feels good to operate and there is also weather sealing and rear protective glass to protect the lens from light rain, snow, and dust.

Short Minimum Focusing Distance

The minimum focusing distance is 20cm (0.66ft), which is very short, so it can be used to capture much more, in a variety of ways. It makes it easier to take architecture shots in narrow spaces, food on tables, and pet images with exaggerated perspectives. Take a couple of steps closer to your subject and get creative images!

Fast and Quiet Auto Focus Performance

The AF 12mm F2 X tracks the subject accurately and quickly, whilst the AF operates quietly and smoothly in video recording mode. Samyang's Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the larger and heavier focusing lens groups. In particular, it is advantageous for video shooting as this lens is suitable for use on a gimbal, in combination with the small and light Fujifilm X series cameras.
