4. Betjening af objektivet
4.1 Autofocus (AF) System
The lens features a Linear STM autofocus motor, providing fast, smooth, and quiet autofocus performance. This is beneficial for both still photography and video recording, minimizing focus breathing.
4.2 Focus Hold Button
The Focus Hold Button allows you to lock the focus at a specific distance. This button can often be customized via your camera's menu to perform other functions, such as Eye AF activation.
4.3 Custom Switch
The Custom Switch provides additional control options. In its default setting, it may control aperture silently, which is useful for video. Refer to your camera's manual for potential customization options for this switch.
4.4 Fokusområdebegrænser
The Focus Range Limiter switch optimizes autofocus speed by restricting the focus range. This is particularly useful when you know your subject will be within a certain distance, preventing the lens from hunting across its full focus range.
- FULD: Giver mulighed for fokusering over hele området (0.69 m til uendeligt).
- 0.69m - 2m: Limits focus to close-up distances (0.69 meters to 2 meters).
- 1.5m - ∞: Limits focus to longer distances (1.5 meters to infinity).

4.5 Manuel fokus (MF)
To use manual focus, set your camera to MF mode. Rotate the focus ring on the lens to adjust focus. The lens features a micro-pattern focus ring for enhanced grip and precise control.
4.6 Aperture and Bokeh
The wide F1.8 aperture allows for significant light gathering and shallow depth of field, producing smooth, aesthetically pleasing background blur (bokeh). The optical design, including an ultra-precision aspherical lens, contributes to refined and natural bokeh.

4.7 Minimum Focusing Distance
The lens has a minimum focusing distance of 0.69 meters (2.26 feet) and a maximum magnification of 0.243x, enabling detailed close-up photography.
5. Vedligeholdelse og pleje
- Rengøring af linsen: Use a soft, lint-free cloth or a lens brush to remove dust. For smudges or fingerprints, use a specialized lens cleaning solution and a microfiber cloth. Apply solution to the cloth, not directly to the lens.
- Opbevaring: When not in use, always attach the front and rear lens caps. Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying pouch for added protection.
- Vejrforsegling: The lens features weather sealing to protect against dust and light moisture. While it offers protection, avoid exposing the lens to heavy rain or submerging it in water.
