5. 렌즈 작동

자동 초점(AF) 및 수동 초점(MF)

The EF-M 22mm f/2 STM lens supports both autofocus and manual focus. The STM (Stepping Motor) technology provides exceptionally smooth and quiet autofocus, which is particularly advantageous when shooting video, as it minimizes distracting focus motor noise. For precise control, switch to manual focus mode on your camera.

Aperture and Low-Light Performance

With a wide maximum aperture of f/2.0, this lens allows a significant amount of light to reach the camera's sensor. This makes it highly effective for shooting in challenging low-light conditions without needing to drastically increase ISO sensitivity. The wide aperture also enables shallow depth of field, creating a pleasing background blur that isolates your subject.

클로즈업 사진

The lens features a minimum focusing distance of just 0.15 meters (5.9 inches). This allows you to get very close to your subjects, capturing intricate details and achieving a near-macro effect. Experiment with this feature for creative close-up shots.

Understanding STM Lenses

The Stepping Motor (STM) is a type of autofocus motor designed by Canon to provide smooth and quiet focusing, especially during video recording. Unlike traditional ultrasonic motors (USM) which can be noisy, STM lenses are optimized for silent operation, preventing unwanted audio interference in your videos.
