Released December 2024. The first α lens to achieve an F2 maximum aperture across the entire zoom range. This compact, lightweight, fast standard zoom lens, G Master, combines high resolution approaching that of a prime lens with natural bokeh. Mount: E-mount lens (compatible with full-frame mirrorless cameras). Focal length: 28-70mm. Aperture: F2. Filter diameter: 86mm. [SEL2870GM]SEL2870GM Released December 2024. The first α lens to achieve an F2 maximum aperture across the entire zoom range, the G Master offers versatile flexibility for a wide range of photography. It's ideal for capturing a variety of subjects, including portraits. With an F2 maximum aperture across the entire zoom range (from 28mm wide-angle to 70mm medium telephoto), it delivers resolution and contrast approaching that of a prime lens, plus impressive AF performance—all without sacrificing size or weight—all in an incredibly compact, lightweight design. This lens, embodied in Sony's latest lens design technology, will open up new horizons for creative professionals.
A compact and lightweight design despite its constant f/2 maximum aperture. It delivers optical performance approaching that of a prime lens and outstanding AF performance throughout the entire zoom range from 28mm to 70mm, making it ideal for a wide range of applications. By employing an optimized optical system and four XD (extreme dynamic) linear motors, this lens achieves unprecedented lightness and compactness, measuring a maximum diameter of 92.9mm, length of 139.8mm, and weighing approximately 918g.
Resolution that maximizes the camera's performance. The latest optical design and optical simulation technology deliver imaging performance approaching that of a prime lens throughout the entire zoom range, from the wide-angle end of 28mm to the telephoto end of 70mm. The use of three large-aperture, ultra-high-performance XA (extreme aspherical) lens elements achieves a maximum aperture of f/2 with high resolution from the center to the periphery of the image. In addition, three Super ED glass elements and one ED (Extra-Low Dispersion) glass element are optimally positioned to correct chromatic aberration. This reduces chromatic aberration at the center and periphery of the image, preventing a loss of resolution. Furthermore, color bleeding is effectively suppressed across the entire image, resulting in superior clarity and resolution.
High-speed, high-precision, and highly responsive AF drive. Reliable tracking and high-speed performance are essential for scenes where every moment counts, such as weddings and sporting events. Four optimized XD linear motors and the latest lens control technology precisely control the large and heavy focus lens group with an aperture of f/2. It also has tracking capabilities that are compatible with the α9 III's high-speed continuous shooting speed of approximately 120 frames per second, and tracking continues even when zooming.
Video performance that meets the needs of video creators. It also supports the α series camera's breathing compensation function. This suppresses fluctuations in the angle of view during focusing, enabling sophisticated video production. In addition, the shallow depth of field at F2 allows for smooth, natural transitions when changing focus or zooming. Precise focusing is possible even when shooting at high frame rates such as 4K 120p/FHD 240p. The XD linear motor and newly developed circular aperture unit operate quietly.
Mastered Operability and Reliability. Features include two focus hold buttons that can be customized from the body, a focus mode switch, aperture ring, and iris lock switch. The high operability of the linear response MF allows for capture that meets the creative sensibilities of creatives. A variety of functions ensure excellent operability and reliability in any environment. The filter diameter is 86mm.
Reliability for shooting in a variety of environments [Dust- and splash-proof design*] The lens features a dust- and splash-proof design*, ensuring reliability even in outdoor shooting environments. [Fluorine coating] The fluorine coating applied to the front lens element makes it less likely for fingerprints, dust, water droplets, oil, and mud to adhere to the lens surface, and even if they do adhere, they can be easily removed. *Although the lens is designed to be dust- and water-resistant, it does not completely prevent dust and water from entering.
