4.1 Autofocus (AF) System

The YN11mm F1.8S DA DSM lens utilizes Digital Stepping Motors (DSM) for fast, precise, and quiet autofocus. This system is highly reliable for both still photography and video recording. The lens provides excellent video autofocus performance with good respiratory effect control, minimizing focus breathing during video capture.

4.2 Blenderåpningskontroll

The lens features a large F1.8 aperture, allowing for excellent low-light performance and beautiful background blur (bokeh). You can adjust the aperture using the dedicated aperture ring on the lens. The aperture ring offers both click-stop adjustment for precise control and a click-less (OFF) mode for silent operation during video recording.

4.3 Optical Performance

This ultra-wide-angle lens delivers outstanding image quality with excellent center-to-edge resolution. It incorporates specialized optical elements, including aspherical lenses and low-dispersion glass lenses, to effectively suppress various aberrations and control flare and ghosting, even when shooting against bright light sources. This ensures clear and sharp images, particularly beneficial for astrophotography where point light sources remain distinct without flare.

The lens boasts a minimum focusing distance of 0.15m (approximately 0.49ft), allowing for close-up shots with a natural defocus performance, creating pleasing bokeh effects.

4.5 Trådløs fjernkontroll

The YN11mm F1.8S DA DSM lens supports wireless remote control via Bluetooth. This feature allows for convenient focus and aperture adjustments, including A-B focus switching and adjustable zoom speed, enhancing your creative control, especially in video production or when the camera is mounted on a gimbal or drone.

5. Vedlikehold

5.1 Rengjøring av linsen

To clean the lens surface, use a soft, lint-free microfiber cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens). Avoid using abrasive materials or harsh chemicals.

5.2 Oppbevaring

When not in use, store the lens with both front and rear caps attached in a dry, cool place away from direct sunlight and extreme temperatures. Consider using a desiccant packet in your camera bag or storage area to prevent mold and mildew, especially in humid environments.
