Lightweight, High-Performance, and Customizable Design: TTArtisan Launches 'Neo AF 50mm f/1.8'

Sokokoubo Co., Ltd. announces the launch of the TTArtisan 'Neo AF 50mm f/1.8'—a full-frame dedicated autofocus standard prime lens from the new 'Neo' series—on July 4, 2026 (Saturday).

The 50mm standard angle of view is ideal for a wide range of scenes, including everyday snapshots, portraits, tabletop photography, and travel landscapes.

This lens combines that versatile field of view with a bright f/1.8 aperture, quiet and smooth autofocus, and a lightweight, compact design that's easy to carry. Additionally, it offers unique customization options for the外观, allowing users to personalize the look of the lens—a signature feature of the new 'Neo' series.

"I want to minimize complicated operations, but still capture beautiful photos."

This simple, user-friendly standard prime lens is perfect for anyone who feels this way.

Lightweight and Compact Design You’ll Want to Carry Every Day

Despite supporting full-frame sensors, the lens weighs approximately 156g (Sony E-mount), making it exceptionally lightweight.

As an f/1.8 large-aperture standard lens, it offers excellent portability and a compact form factor that can be comfortably carried even when mounted on a camera.

For example, capturing striking cityscapes during summer walks, spontaneous moments on a trip, a dish at a café, or soft light by a window.

Even on days when you want to travel light, this lens is easy to bring along, increasing the chances that you’ll think, "I should take my camera today."

Natural Bokeh and Dimensionality from f/1.8

The bright f/1.8 aperture delivers a soft, natural bokeh effect that gently lifts the subject.

When photographing people, the background softly melts away; in tabletop photography, it dramatically highlights the main subject; and everyday scenes gain an artistic, almost professional quality.

Additionally, in low-light situations such as indoors or at dusk, it helps maintain faster shutter speeds, reducing camera shake and subject blur.

It also allows for lower ISO sensitivity, resulting in cleaner, noise-free images.

Quiet and Smooth Autofocus That Won’t Miss the Moment

Equipped with an STM (Stepping Motor) for smooth, silent autofocus operation.

Supports eye AF and subject recognition AF, making it ideal not only for portrait photography but also for capturing moving subjects comfortably.

The dedicated AF design intentionally omits focus and aperture rings, resulting in a clean, minimalist appearance and intuitive operation.

This makes it easy to use even for first-time prime lens users, allowing them to focus entirely on shooting.

A New Concept from the Neo Series: Enjoying Not Just Image Quality, But Also Appearance

One of the standout features of this product is the customizable外观 enabled by 3D-printable data for custom armor (barrel covers).

By customizing the color and texture to your preference, the lens becomes not just a tool for capturing images, but also a personal expression of your style.

As photography becomes more diverse, the joy of ownership and emotional attachment are becoming just as important as image quality when choosing a lens.

The 'Neo AF 50mm f/1.8' aims to be a new standard that aligns with modern photography styles.

The dedicated 3D data can be downloaded from the 'Sokokoubo Online Store product page'.

Optical Design Optimized for Edge-to-Edge Performance

The lens construction consists of 8 groups and 12 elements, including 2 ED lenses and 4 high-refractive lenses, delivering excellent image quality from the center to the edges of the frame.

It naturally preserves atmosphere in snapshots while softly highlighting subjects in portraits.

This standard lens balances everyday usability with high image quality suitable for creative work.

Firmware Updates Supported

The included rear lens cap features a USB Type-C port.

Connecting to a PC enables firmware updates.

This is a welcome feature for users who want to use the lens reliably over the long term.
