Sharpness that Captures Every Expression
The AF 85mm F1.8 P FE lens delivers outstanding sharpness specifically tailored for portrait photography at distances ranging from 2 meters to 3 meters. Its advanced optical design, featuring three ED (extra-low dispersion) elements, effectively eliminates chromatic aberration and ensures precise detail reproduction at the center of the frame. This lens captures fine details, such as eyes, eyelashes, and skin texture, with great precision, allowing for a natural and vivid expression of the subject’s emotions.
Creamy Bokeh that Enhances Subject Separation
The bright F1.8 aperture creates a beautifully shallow depth of field that naturally isolates the subject, while the smooth bokeh enhances the emotional expression and presence of the portrait. Coupled with the 85mm focal length, this soft out-of-focus effect ensures powerful expressiveness, making it an essential choice for striking portrait photography.
Soft, Rounded Bokeh that Surrounds the Subject
With its 9-blade rounded aperture, this lens creates stunningly smooth and nearly circular bokeh, even at wide-open settings. This consistent and beautiful rendering of point light sources gently highlights the subject, blending the background seamlessly while ensuring that the focus remains on what truly matters. The lens’s exceptional ability to render each light source with precision dramatically elevates the emotional impact of portrait images.
Bringing Depth to Every Expression
The AF 85mm F1.8 P FE lens provides a smooth depth of field that seamlessly transitions from the subject to the background, resulting in harmonious and well-balanced portraits. The seamless transition between focused elements and the background adds emotional depth to each image, creating an immersive visual experience.
All-new Features
The lens body is made from a specially developed, high-strength engineering plastic that combines a lightweight design with excellent durability and a premium finish. The newly designed lens hood effectively blocks unwanted light, minimizing flare and ghosting, which results in clearer and sharper images.
Compact Design Packed with Essential Features
The AF 85mm F1.8 P FE is designed to include only the essential features that creators need, all within a compact and lightweight body. It features a dedicated AF/MF switch for quick and easy control, and it has a USB-C port on the lens mount for simple firmware updates. According to internal tests conducted by LK SAMYANG, the lens achieves an IP5-level dust resistance, offering reliable protection against everyday dust and light moisture.
