7Artisans announces its first 50mm F1.8 lens with autofocus. Release date: March 19, 2023. Manufacturer's suggested retail price: ¥34,359 (tax included).

Realism with 50mm Focal Length

The 50mm focal length captures details sharply and expresses the realistic texture of subjects. It avoids spatial compression, naturally depicting the subject and its surroundings, enabling vibrant photography.

Beautiful Background Blur with Bright Aperture

The bright F1.8 aperture emphasizes background blur, making the subject stand out sharply. The image gains a simpler and smoother blur effect, resulting in artistic and storytelling photographs.

High-Performance Stepping Motor (STM)

Equipped with a stepping motor (STM) that achieves fast and reliable autofocus. Autofocus and optical performance are enhanced, making it easier to focus on shooting tasks. Additionally, the full-metal lens body is robust enough to withstand harsh shooting environments. 

Advanced Lens Configuration for Sharp Images

Also features face detection and eye AF support, automatically focusing on the subject's face and eyes for sharp shooting. The AF/MF switch function uses the aperture ring, allowing switching between autofocus and manual focus. Even when the aperture is wide open, image quality does not degrade, and it excels in distortion aberration and saturation management.
