Overwhelming resolution that defies conventional wisdom about fisheye lenses. 35mm full-frame compatible F1.4 diagonal fisheye lens. Mount: Sony E-mount. Full-frame compatible. Focal length: 15mm. Maximum aperture: F1.4. Filter diameter: -. Art line / [1514DGDNSE] 1514DGDNSE Released in March 2024. Overwhelming resolution that defies conventional wisdom about fisheye lenses! 35mm full-frame compatible F1.4 diagonal fisheye lens. In developing a fisheye lens characterized by its ultra-wide angle and impressive distortion effect, SIGMA achieved a world-first* for a consumer lens, combining a bright F1.4 aperture with high resolution across the entire frame. In terms of optical performance, excellent correction of various aberrations, particularly sagittal coma flare, delivers excellent point image reproduction and high resolution. Even in starry sky photography, which demands exceptional performance, this lens is fully capable, even at full aperture. Its unparalleled imaging capabilities, capturing every corner of the 180° angle of view with high resolution, defy conventional fisheye lenses. Its exceptional imaging capabilities not only allow for classic scenes like starry skyscapes and architecture, but also open up entirely new possibilities for creative expression. *As an interchangeable lens for consumer 35mm full-frame cameras. (As of February 2024, according to Sigma research)
... By effectively correcting various aberrations, particularly sagittal coma flare, this lens achieves point-image reproduction and high resolution sufficient for starry sky photography, even at wide apertures.
180° Diagonal Fisheye Lens: The impressive distortion effect that is the hallmark of fisheye lenses allows you to enjoy a unique sense of perspective and subject emphasis across the entire 180° angle of view. In addition, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is designed to the strict standards of the Art line in terms of performance. Furthermore, every lens is inspected using SIGMA's proprietary MTF measuring device. The unique expression of fisheye lenses combined with astonishingly high resolution delivers unparalleled imaging capabilities, enabling expression beyond the bounds of conventional fisheye lenses.
Designed to Address Flare and Ghosting: Flare and ghosting, which degrade image quality, are addressed using cutting-edge simulation technology to address all types of incident light. High backlight resistance ensures clear, crisp images in any lighting conditions. The MFL (Manual Focus Lock) switch disables focus ring operation when set to LOCK. This prevents unintentional focus shifts caused by the focus ring. This is useful for long-exposure photography, where the focus is fixed. Lens Heater Retainer: The lens heater retainer, a step around the front, prevents the lens heater from protruding in front of the lens and causing vignetting around the edges of the image. Rear Filter Holder: The lens mount is equipped with a rear filter holder that can accommodate sheet-type rear filters as standard. Dedicated Cover Lens Cap: A cover lens cap with a locking mechanism is included. It also has filter slots that can accommodate two rear filters depending on the application. The cap is designed specifically for the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art, protecting sheet filters from scratches and dirt and preventing misplacement or forgetting them. Arca-Swiss Compatible Tripod Mount: The included tripod mount is lightweight and durable, made of magnesium alloy and is compatible with Arca-Swiss lenses. It can be mounted on a tripod stably, even for long exposures. The design is also thoughtful to prevent interference when using the lens heater.
Equipped with a variety of cutting-edge features and high-quality build: It is equipped with a variety of shooting-assistance functions, including an AFL button and aperture ring that can be assigned to any function. The AF actuator uses a linear motor, the HLA (High-response Linear Actuator), for fast, quiet, and highly accurate AF. It also boasts a dust- and weather-resistant construction and high build quality for long-term reliable use in any environment.
Equipped with a variety of shooting-assistance functions: It features an AFL button that can be assigned to any function. In addition to the aperture ring, it also features an aperture ring lock switch and a click switch that can be used to turn the click on and off.
Dust- and weather-resistant construction with a water- and dirt-repellent coating: In addition to the dust- and weather-resistant body, the front of the lens is coated with a water- and dirt-repellent coating, allowing you to shoot with confidence even in harsh outdoor conditions.
