[What is Dolly shot?] 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.

A large aperture starting from F2 presents an attractive background blur to the image's out-of-focus areas. The lens 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 clear and natural bokeh created by the 9 diaphragm blades makes it possible to capture beautiful night-time cityscapes.

The perfect spacing and distance are always necessary when shooting all kinds of subjects, including people, to give them a proper relationship with the beautiful space around them. So, what’s the exact distance that helps you best appreciate a work of art, or a photo?

Back when film cameras were common, 45mm was the industry standard and this continued as reflex cameras needed extra space to fit a mirror. However, as mirrorless cameras become more popular again, there has been a need to return to this industry standard…which is the impetus for the Samyang AF 45mm F1.8 FE. With less distortion than a 35mm lens and wider angles than a 55mm lens, the Samyang AF 45mm F1.8 FE is a perfect lens for portraits, landscapes, architecture photography, and pictures of pets.
