Samyang’s Guide to Achieving the Optimal Angle of View

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?

The correct answer is the diagonal length of the full frame of a subject.

표준화각 자료 이미지
표준화각 자료 이미지

The best standpoint from which to appreciate the full view of a subject is the distance of the diagonal length of the subject frame. This wider angle is superior to standing closer at a 50 degree angle to get a more detailed view. This notion of an ideal distance or view point is also applicable in the world of photography.

For still images, keeping a distance equal to the diagonal length of the full image surface is recommended. The full frame sensor of a digital camera is 36 x 24mm and the diagonal length is 43.26mm so any distance close to this number is nearer to the ideal than the currently accepted industry standard of 50mm.

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.

What is Preset Aperture Control Function?

On the Preset Aperture Control function, the aperture blade operates smoothly like a "De-clicked lens", which is advantageous for video recording.
Fujifilm cameras are engineered to control the aperture according to the minimum exposure value(F-stop), so when the camera controls the aperture, it blinks momentarily to set the proper exposure.

AF 75mm F1.8 X intentionally disconnects the communication with the camera body and the lens itself on the Preset Aperture Control function, so it is possible to smoothly adjust the exposure without flickering. ISO and shutter speed are adjusted according to the changed exposure by controlling the aperture, so the exposure value can be changed even with the 1/2 F-stop.

[What is Dolly Shot? How to Shoot Easily]

[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.

[How to take a Dolly Shot simply by handheld]

Tip. If the moving distance is long, the camera may shake, so please shoot at a focal length between 35 and 100mm.
1. Stand at a distance of about 1.5 to 2 meters away from the subject.
2. Set the custom switch to MF and Mode 3 and adjust the focal length to about 100mm.
3. After focusing on the subject, set the aperture to F8~16.
4. Slowly turn the zoom ring to the left (towards the wide-angle end) while using your upper body and arms to move the camera toward your subject.
5. Dolly Shot complete!
※ When shooting from a farther distance from the subject, use a cart or gimbal for more stable shooting.
