After extensive research and development, the Fe 12-24mm f/2.8 Gm Lens for Sony E-Mount emerges as a high-quality, professional-grade lens, specifically designed for Sony E-Mount cameras. This advanced lens offers an ultra-wide zoom range of 12-24mm at a constant f/2.8 aperture, providing photographers with the flexibility to capture stunning landscapes, night scenes, and architectural shots with ease. The lens features an innovative optical design, incorporating Sony's advanced Xd Linear Motors to deliver outstanding G Master image quality. This design, coupled with the largest Xa element ever made for any Alpha lens, ensures stunning resolution throughout the image area. The lens also boasts two Super Ed (Extra-low Dispersion) and three Ed glass elements that suppress chromatic aberration, maintaining maximum sharpness and preventing color smearing across the image area. This feature is particularly beneficial for large-aperture lenses, ensuring high-quality images in challenging lighting conditions. The Fe 12-24mm f/2.8 Gm Lens is equipped with a new Nano Ar Coating Ii, designed to suppress internal reflections that can cause flare and ghosting. This coating ensures high clarity and contrast throughout the entire image, even in difficult light. Despite its advanced features, this lens is surprisingly lightweight, weighing only 29.88 ounces. Its compact design, coupled with high-performance Xd Linear Motors, makes it an ideal choice for active sports photographers seeking to use ultra-wide angles. The lens also offers a floating focus mechanism that divides the lens's focus group into two independently controllable groups, minimizing aberration that varies with focusing distance. This mechanism ensures top performance from infinity to close-up focus, across the entire zoom range. The constant f/2.8 maximum aperture allows for flexible moviemaking, as aperture does not change while zooming. This feature ensures consistent exposure, shutter speed, and Iso sensitivity while shooting movies. The lens is designed with a dust and moisture-resistant exterior, providing the reliability needed for outdoor use in challenging conditions. The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface. The lens also features a rear filter holder for standard sheet-type Nd, color correction, and other filters, expanding its expressive capability. A conveniently placed focus hold button offers easy focus hold control and can be assigned to a variety of other functions from a menu accessed via the camera body.
