A dolly shot, also referred to as a tracking shot or trucking shot, is a camera movement technique used by cinematographers to track and follow a subject in motion. To achieve this, the camera is mounted on a device called a "dolly," which facilitates smooth tracking movement. The dolly can move in front of, behind, or alongside the subject, which can be a person, a location, a product, or any other object of focus in the frame. Through this, you can control the emotional distance between the subject and the viewer by highlighting the audiovisual and dramatic effects.

The Samyang AF 35-150mm F2-2.8 E 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. Short Minimum Focal Distance 0.33m (1.08ft) The AF 35-150mm F2-2.8 delivers superior close-up shooting performance for an all-rounder zoom. At the 35mm wide-angle end, the MOD (Minimum Object Distance) is 0.33mm. Combined with the lens's fast apertures, it produces a unique perspective close to the subject while presenting a beautifully blurred background. Users can also take dynamic close-up shots at the 150mm telephoto end with a MOD of 0.85m. It makes taking portraits with exaggerated features easier, food on tables, etc.

*The focusing ring operates as the aperture adjustment and Linear MF Functions in MODE 2 *The mode can be customized via the optimal Lens Station in Linear MF mode, focus movement is constant regardless of the speed at which the focus ring is turned through its 300º rotation. When using a follow focus, this allows a more precise control.

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 to take the dolly shot easily. 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 when zooming in or out. Since this function is usually mounted in expensive cine zoom lenses, it provides a more special experience and results to customers who use this zoom lens.

The lens’ Linear Stepping Motor (STM) is fast and highly responsive to photographers and videographers. It delivers excellent focus tracking and smooth transitions, from the Minimum Object Distance (MOD) to infinity. Its 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 the Eye AF camera functions as in-camera lens corrections for shading, chromatic aberration, and distortion.

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. Weather-sealed Design Considering the users’ shooting environment, the lens is designed to be completely weather-sealed at the mount and throughout the body. Weather sealing is adopted in 11 areas to prevent damage or contamination from dust, light rain, and snow.

The large aperture of the AF 35-150mm F2-2.8 E 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.
