SG-image announced their newest interchangeable lens, the “SG-image 25mm F1.8.” The SG-image 25mm F1.8 is a manual focus prime lens compatible with APS-C cameras. With a natural angle of view equivalent to approximately 37.5mm in 35mm format, it is suitable for a wide range of scenes, from snapshots to portraits and tabletop photography. The bright F1.8 aperture allows for expression that makes use of a shallow depth of field, increasing the freedom of photography even in limited light environments such as indoors or at dusk.
The optical design, which consists of seven elements in five groups, including three high-refractive-index lenses, achieves a balance between natural depth that enhances the subject’s presence and soft bokeh. The minimum focusing distance is just 0.25m, making it suitable for close-up shots of food and small items. It also enables impressive close-ups with a greatly blurred background.
The lightweight and compact design of the camera body, weighing approximately 160g, makes it highly portable and easy to carry for everyday use and travel. The exterior uses a metal lens barrel (full metal body), which combines light weight with a high sense of rigidity and quality. The focus ring has a moderate torque and the aperture ring has a click mechanism, providing the reliable and intuitive operability that is unique to manual focus.
SG-image 25mm F1.8 Main Features
- Large F1.8 aperture creates a three-dimensional effect: The brightness of the F1.8 aperture sharply captures the focal plane while softly blurring the background, creating an impressive three-dimensional effect. Great for low-light environments such as at dusk or indoors.
- Compact design for excellent portability: Compact enough to throw in your bag while still attached to your camera. Lightweight design makes it a “single focal length lens you can carry every day” that blends into your daily life, even when walking around town for long periods of time.
- Get close to the subject with a minimum focusing distance of 0.25m: The lens offers excellent close-up shooting capabilities, allowing you to get as close as 25cm from the subject. This makes it easy to capture close-up details of food, small items, flowers, and other subjects.
- A full metal body that stimulates the desire to own it: The lens barrel is made of high-quality metal, which not only improves the operability when shooting, but also enhances the joy of carrying it around.
- Reliable manual focus operation:
The focus ring has just the right amount of torque, and the aperture ring has a click mechanism, providing intuitive support for exposure setting operations.
