3. Configuració
3.1 Fixació de l'objectiu a la càmera
- Assegureu-vos que la càmera estigui apagada.
- Traieu la tapa posterior de l'objectiu i la tapa del cos de la càmera.
- Alinea el punt vermell del cilindre de l'objectiu amb el punt vermell de la muntura de l'objectiu de la càmera.
- Introduïu l'objectiu a la muntura de la càmera i gireu-lo en sentit horari fins que faci clic. No forceu l'objectiu.
3.2 Fixació del parasol de l'objectiu
The rectangular metal lens hood helps to prevent flare and protect the front element. Align the hood with the lens and twist gently until it locks into position. Ensure it is securely attached and correctly oriented.
3.3 Removing Lens Caps
Before use, remove the front lens cap by gently pulling it off. To remove the rear lens cap, twist it counter-clockwise while holding the lens firmly.
4. Funcionament de l'objectiu
4.1 Enfocament
The Leica Elmarit-M 28mm f/2.8 ASPH is a manual focus lens. To focus, rotate the focus ring until your subject appears sharp in the viewfinder. The distance scale on the lens barrel indicates the current focus distance in both meters and feet.
4.2 Adjusting Aperture
The aperture ring is located near the camera mount. Rotate this ring to select your desired aperture (f-stop). The lens offers apertures from f/2.8 (wide open) to f/22 (minimum aperture). A wider aperture (smaller f-number) allows more light and creates a shallower depth of field, while a narrower aperture (larger f-number) allows less light and creates a greater depth of field.
4.3 Depth of Field Scale
The depth of field scale on the lens barrel provides an indication of the range of distances that will appear acceptably sharp at a given aperture and focus distance. Use this scale to pre-focus or to understand the extent of sharpness in your images.
5. Manteniment i cura
5.1 Neteja de la lent
- Elements de la lent: Use a soft lens brush or a blower to remove dust. For smudges or fingerprints, apply a small amount of lens cleaning fluid to a clean microfiber cloth and gently wipe the lens surface in a circular motion from the center outwards. Avoid excessive pressure.
- Cos de la lent: Wipe the lens barrel with a clean, dry, soft cloth. Do not use harsh chemicals or solvents.
5.2 Emmagatzematge
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. If storing for extended periods, consider using a dehumidified environment to prevent mold growth.
5.3 Precaucions generals
- Eviteu exposar la lent a canvis sobtats de temperatura, ja que poden causar condensació.
- Do not drop or subject the lens to strong impacts.
- Mantingueu la lent allunyada de camps magnètics forts.
- No intenteu desmuntar la lent. Les reparacions només les ha de realitzar personal de servei autoritzat.
