The Fast All-Rounder Zoom - The Samyang AF 35-150mm F2-2.8 FE has a maximum aperture of F2 at its widest and F2.8 at the telephoto end, which covers the five main focal lengths (35/50/85/135/150). With its wide zoom range, the lens is designed as a fast all-rounder that covers a broad range of shooting scenarios, from portraits to travel. The premium design and performance of 2nd Generation lenses have been applied to the lens, and it also supports the key features of recent Sony mirrorless bodies, including Hybrid AF, Eye AF, Direct Manual Focus (DMF), and the AF assist function.AF 35-150mm F2-2.8 FE Key Features Covering everything between 35mm and 150mm - Samyang has moved a step forward with its innovative second-zoom lens to provide a more convenient user experience. The lens is remarkably versatile as an all-in-one lens with fast maximum apertures and provides a solution for photographers seeking to avoid lens changing. It was clearly designed for a portrait photographer, but the wide zoom range is also useful for everyone shooting commercials, events and travel imagery. Outstanding Resolution, from corner-to-corner. Thanks to the latest optical design of 21 elements in 18 groups and featuring an optimal combination of 2 ASP, 1 HB, 3 HR and 6 ED elements the lens presents superior optical performance throughout the entire zoom range. When combined with Sony’s full-frame image sensor, the AF 35-150mm F2-2.8 FE delivers high image quality to the edges of the frame with plenty of contrast. Fast and accurate AF performance - The lens’ Linear Stepping Motor (STM) is fast and highly responsive to both photographers and videographers. It delivers excellent focus tracking and smooth transitions, from the Minimum Object Distance (MOD) to infinity. It’s fast maximum aperture also helps you control camera movement by allowing a higher shutter speed or reducing noise by choosing a low ISO. The system is compatible with Sony’s Fast Hybrid AF, and Eye AF camera functions as in-camera lens corrections for shading, chromatic aberration, and distortion. Impressive bokeh with a bright F2-F2.8 aperture - The large aperture of the AF 35-150mm F2-2.8 FE presents an attractive background blur to the image's out-of-focus areas. It effectively separates the subject from the background, using a shallow depth of field to capture a unique image in which the background is compressed. The lens employs 9 diaphragm blades, creating a smooth and attractive bokeh. Premium design and usability. Since introducing the 2nd Generation lenses, Samyang has introduced the 'Hidden red ring' design that has become part of the brand’s design identity. The new design improves the look and usability of the lens, reflecting customer feedback, with enhanced tactile controls for focusing and precise focal length adjustment. A lock switch on the body helps users keep the lens set at its shortest 35mm position and is useful for protection during travel. Enhanced Functionality with custom switch & button - The two round buttons made of soft rubber have a focus save function which can store 2 points of focus. In addition, three custom mode switches on the lens can be pre-programmed via the optional Lens Station, allowing you to set up the mode to suit your preference. Optimized features for video shooting - 1) Dolly Zoom Shot: The Dolly Zoom is a powerful in-camera cinematic technique. A professional dolly can be expensive and challenging to operate, but this lens allows you easily take the dolly shot. 2) Cinematic Video AF: When shooting video, the AF speed is more carefully adjusted than photo shooting, resulting in lower wobbling and highly stable movie shooting. 3) Linear MF Focus Control: Provides convenience to video shooters by matching the torque of the focus ring as closely as possible to that of a manual focus lens when shooting video in manual mode. 4) Digital Par-Focal: Digital Par-focal is specialized for video shooting as it can maintain focus on the subject
