Brightin Star announced the new 50mm F2 TRI-SIGHT lens. This is a full-frame compatible interchangeable lens. Autumn and winter are the seasons when the city lights shine beautifully. Portraits with illuminations as a backdrop, or the light reflecting on the road after the rain—even ordinary scenes can take on a completely different impression depending on how the light is captured.
The Brightin Star “50mm F2 TRI-SIGHT” is a manual focus lens designed for freely enjoying the nuances of light.
Three Bokeh Rendering Styles in One Lens
“SMOOTH” creates a soft, diffused light; “PRIME” provides natural and clear images; and “FOAMS” creates a bubble-like bokeh effect. A unique mechanism that moves the optical elements inside the lens back and forth changes the optical properties of the lens itself, without relying on effect filters or digital processing.
Whether you want to capture familiar scenery naturally, depict it in a soft, dreamy way, or transform background light into a striking accent, you can choose the style of rendering that suits your mood or the image you want to capture, without having to change lenses.
Overview of the Brightin Star 50mm F2 TRI-SIGHT Settings
SMOOTH | A gentle depiction that softly envelops the light.
This mode softly diffuses light in bright areas, creating a gentle atmosphere. It gently diffuses highlights while preserving the subject’s outline and details. It also makes it easier to render skin tones smoothly, making it suitable for portraits and photography where atmosphere is important.
For example, portraits taken on a street corner at dusk, or indoor shots that utilize the light streaming in through a window. It adds a touch of warmth to your usual photos.
PRIME | Standard mode for naturally and beautifully capturing everyday life
This basic mode allows you to enjoy natural and clear depictions. It’s useful in a variety of everyday situations, such as street photography, landscapes while traveling, and table photos at cafes.
The appeal of this lens lies not only in its distinctive bokeh effect, but also in its ability to be enjoyed as an everyday 50mm lens.
FOAMS | Transforms nighttime light into bubble-like bokeh
This mode highlights the outlines of light in the background, creating a ring-shaped bubble bokeh effect. For example, the illuminations decorating street trees, the lights lining a city at night, or the light reflecting off a road after the rain.
Small lights that would normally be just background blur are transformed into a bokeh effect with a strong presence, like soap bubbles, making the entire photograph more impressive. This is a rendering technique you’ll want to actively try in light-filled scenes, such as nightscapes in autumn and winter or portraits with illuminations in the background.
*The minimum focusing distance differs for each mode.
Change the shape of light.
In addition to the three rendering modes, another enjoyable feature is the “aperture insert system.”
By attaching a special aperture insert to the rear of the lens, you can change the shape of the bokeh of point light sources in the background in various ways.
The included inserts come in four designs: a rounded triangle, a butterfly, a four-leaf clover, and a star.
For example, when photographing a person with illuminations in the background, you can enjoy a playful and unique photo by changing the background lights into the shapes of stars or butterflies.
If you want to emphasize the shape of the bokeh, it is effective to open the aperture to F2 and blur the small lights in the background when taking the picture.
You can not only manipulate how light diffuses, but also the shape of the light itself. This kind of freedom of expression expands the unique photographic experience offered by this lens.
Perfect for both photos and videos. A mechanical design that makes operation enjoyable.
The lens barrel features a robust all-metal construction. Its mechanical design, achieved through high-precision CNC machining and anodized finish, is also a major draw.
It features a stepless aperture ring for smooth aperture control and a removable focus lever. It can be used not only for still photography but also for video recording where capturing the atmosphere of light is important.
Focusing manually and choosing the lens’s rendering while shooting—the unique feel of manual focus is one of the joys of photography.
Furthermore, it features an integrated, retractable lens hood, demonstrating consideration for ease of carrying and handling during shooting.
The included UV filter is only about 0.7mm thick when attached. It uses optical glass with a multi-layer coating that suppresses light reflection.
The joy of choosing the way things are depicted, rather than changing the lens.
Whether you want to enjoy natural depictions, capture soft and gentle portraits, or create unique works where light takes center stage, this camera is perfect for you.
The “50mm F2 TRI-SIGHT” combines multiple expressive capabilities into a single lens, proposing a new shooting style where you can choose the lens’s characteristics to match the image you want to capture.
