Funcionament de la lent
1. Interruptor de mode d'enfocament (AF/MF)
The lens features a switch on the barrel to select between Autofocus (AF) and Manual Focus (MF) modes. Slide the switch to your desired mode.
- AF (enfocament automàtic): The camera will automatically focus on your subject. This mode is ideal for most shooting situations.
- MF (enfocament manual): Allows you to manually adjust the focus by rotating the focus ring on the lens. This is useful for precise focusing in specific scenarios or when autofocus struggles.

2. Control d'obertura
The lens features an aperture ring for direct control over the aperture setting. You can choose between F2.0 (wide open) to F16. The wider aperture (smaller f-number) allows more light and creates a shallower depth of field (more background blur), while a narrower aperture (larger f-number) allows less light and creates a deeper depth of field (more in focus).

3. Demonstrating Aperture Effects (Daylight)
Video 2: This video demonstrates the effect of different aperture settings (F2.0 to F16) on depth of field and background blur in daylight conditions.
4. Demonstrating Aperture Effects (Night Scene)
Video 3: This video illustrates how varying aperture settings (F2.0 to F16) impact the appearance of night scenes, particularly bokeh and light rendition.
Manteniment
1. Neteja de la lent
- Feu servir un drap suau i sense borrissol o un raspall per a lents per eliminar la pols de les superfícies de les lents.
- For smudges or fingerprints, apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the lens in a circular motion.
- Eviteu tocar els elements de vidre directament amb els dits.
2. Emmagatzematge
- Always attach both front and rear lens caps when the lens is not in use.
- Guardeu la lent en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- If storing for extended periods, consider using a dehumidifying cabinet or silica gel packets to prevent mold growth.
Resolució de problemes
1. Autofocus Issues in Low Light
In very low light conditions, the autofocus system may struggle to acquire focus. This is a common characteristic of many lenses and camera systems.
- Solució: Switch to Manual Focus (MF) mode and adjust focus manually.
- Solució: Use an external light source to illuminate your subject, aiding the autofocus system.
- Solució: Ensure your camera's firmware and the lens's firmware (if applicable) are up to date, as updates can sometimes improve autofocus performance.
2. Vignetting at Wide Apertures
Some vignetting (darkening of the image corners) may be noticeable at wider apertures (e.g., F2.0 to F4). This can be a creative effect for portraits but can also be corrected.
- Solució: Stop down the aperture to a narrower setting (e.g., F5.6 or higher) to reduce vignetting.
- Solució: Vignetting can often be corrected in post-processing software using lens profiles or manual adjustments.
