"A 98° field of view, crystal clear from edge to edge at f/2.8."
The SG-image 12mm F2.8 is an ultra-wide-angle prime lens compatible with APS-C sensors. With a wide angle of view of 98°, it can capture cityscapes and vast natural landscapes without missing any detail. The optical design of 10 elements in 8 groups, including 3 high-refractive-index lenses and 1 aspherical lens, achieves clear, high-contrast images from the center to the corners even at maximum aperture. The bright F2.8 aperture allows for sharp capture of subjects and rich tonal expression even when shooting night scenes and starscapes. Additionally, a minimum focusing distance of 0.2m enables close-up wide-angle photography, supporting diverse shooting scenarios such as dynamic compositions of architecture and landscape expressions that incorporate a large background. Despite featuring a metal barrel, it achieves a lightweight design of approximately 300g, making it suitable for a wide range of shooting scenes from everyday use to travel destinations. In terms of operability, it adopts an aperture ring with clicks and a focus ring with appropriate resistance, supporting intuitive and reliable manual operation.
