A large-aperture wide-angle APS-C prime lens that delivers the expressive power of an ultra-wide 11mm aperture and an f/1.8 maximum aperture in a compact and lightweight package. Mount: Sony E-mount for APS-C mirrorless cameras. Focal length: 11mm. Aperture: f/1.8. Filter diameter: 55mm / [SEL11F18] SEL11F18 Released in June 2022
High-resolution imagery across the entire 11mm ultra-wide angle. By appropriately positioning three aspherical lenses and three ED (extra-low dispersion) glass elements using cutting-edge optical design, we have achieved improved resolution performance from the center to the edges of the image, despite the large aperture of the ultra-wide 11mm (16.5mm equivalent in 35mm format). The appropriate positioning of the aspherical lenses effectively corrects field curvature, achieving high resolution across the entire image, even at maximum aperture. In addition, the use of ED glass reduces chromatic aberration and coma aberration, achieving sharp resolution even at the edges of the image. The ultra-wide angle of view allows you to enjoy dynamic images, such as indoor shots and perspective shots.
Beautiful and Soft Bokeh Rendering: Despite its ultra-wide 11mm angle, the large F1.8 aperture allows you to enjoy background blur, a feat not possible with smartphone photography. For example, you can blur the background to emphasize your face in selfies, or capture beautiful bokeh effects within a wide angle of view in nightscapes. Spherical aberration, which affects bokeh, is controlled, and the seven-blade circular aperture achieves beautiful bokeh.
Excellent close-up shooting capabilities with a minimum focusing distance of 0.12m (MF mode). Excellent close-up shooting performance provides ample shooting flexibility for both still images and video. Get close to your subject and enjoy capturing images with a deeply blurred background. Minimum focusing distance: 0.15m (AF) / 0.12m (MF) Maximum magnification: 0.13x (AF) / 0.20x (MF) Compact and lightweight design for easy portability. Effectively positioned aspherical lenses and an optimal optical design that takes advantage of a short flange focal distance achieve a high-resolution, large-aperture, ultra-wide-angle lens with a diameter of 66x57.5mm and a weight of just 181g. Its size matches the compact APS-C body perfectly. Its compact and lightweight design allows for effortless shooting anywhere, anytime. The system itself is easy to handle, whether handheld or gripped, and allows for stress-free, fatigue-free shooting, even over extended periods of time. Equipped with two high-speed, high-precision, high-tracking, and quiet AF linear motors, it delivers high-speed, high-precision, high-tracking, and quiet AF performance for both stills and video. This maximizes the camera body's speed performance, ensuring continuous capture of even moving subjects. Significantly Reduced Focus Breathing: The latest lens design technology, including an optimized lens configuration, significantly reduces focusing, minimizing fluctuations and shaking in the angle of view remaining on the screen. For example, when taking a selfie, the change in angle of view is significantly reduced when shifting the focus from the background to your face, eliminating any noticeable unnatural shifts. When used with a compatible α series camera*, this lens corrects focus breathing and suppresses post-capture. *Please refer to the manufacturer's page for the latest compatible models. Ideal for Vlogs and Selfies: The ultra-wide 11mm lens's angle of view allows for vlogs and selfies with a large background. The compact and lightweight design makes this lens highly portable and maneuverable, making it a versatile lens for a wide range of subjects, purposes, and situations. Internal Focusing: The internal focusing system maintains the overall lens length when focusing. This versatile system allows for flexible use, allowing for close-up shots and video recording in tight spaces, expanding the scope of expression. Linear Response MF: The focus ring features a linear response MF system that responds responsively to even delicate manual focus movements. The amount of focus movement is determined by the rotation angle of the ring, allowing for precise focusing that directly reflects the photographer's intentions, similar to a mechanically linked ring. Flexible Operation for Ease of Use: The focus hold button can be customized via the camera's menu and assigned to your preferred function. For example, assigning it to [Focus Magnifier] allows you to magnify the image while shooting, conveniently checking whether the focus is correct. The focus mode switch also allows you to instantly switch between AF and MF depending on the shooting situation, supporting smooth shooting. Even though it is an ultra-wide-angle lens, a front filter can be attached. Dust- and Weather-Resistant Design: The lens is designed with dust and weather resistance in mind, ensuring reliability even in harsh outdoor shooting environments. *Although the lens is dust- and weather-resistant, it does not completely prevent dust and water from entering.
