- Muntatura tal-lenti: The part of the lens that connects to the camera body (Leica M-Mount).
5. Setup
Attaching the Lens to the Camera:
- Kun żgur li kemm il-kamera kif ukoll il-lenti huma nodfa u ħielsa mit-trab.
- Neħħi l-għatu tal-lenti ta' wara mil-lenti u l-għatu tal-body mill-kamera.
- Align the red dot on the lens mount with the corresponding red dot on the camera's lens mount.
- Daħħal il-lenti bil-mod fil-muntatura tal-kamera.
- Dawwar il-lenti lejn l-arloġġ sakemm tikklikkja f'postha, u b'hekk tindika li hija msakkra sew.

Focus Manwal:
- Look through your camera's viewfinder
- Rotate the focus ring on the lens until your subject appears sharp and clear in the viewfinder's rangefinder patch.
- The distance scale on the lens indicates the current focus distance.
Kontroll tal-Apertura:
- Dawwar iċ-ċirku tal-apertura biex tagħżel l-f-stop mixtieq tiegħek.
- Smaller f-numbers (e.g., f/2.8) indicate a wider aperture, allowing more light and creating a shallower depth of field.
- Larger f-numbers (e.g., f/22) indicate a narrower aperture, allowing less light and creating a greater depth of field.
Fond tal-Qasam:
The depth of field scale on the lens can be used to estimate the range of acceptable sharpness at a given aperture and focus distance. Align the focus distance with the desired aperture markings on the scale to see the near and far limits of focus.
7. Manutenzjoni u Kura
Manutenzjoni xierqa tiżgura l-lonġevità u l-prestazzjoni ottimali tal-lenti tiegħek.
Tindif tal-Lenti:
- Elementi tal-lenti: Use a soft lens brush or a blower to remove dust particles. 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. Avoid excessive pressure.
- Korp tal-Lenti: Wipe the lens barrel with a clean, dry, soft cloth. Do not use harsh chemicals or solvents.
Ħażna:
- Dejjem waħħal l-għotjien tal-lenti ta’ quddiem u ta’ wara meta l-lenti ma tkunx qed tintuża.
- Aħżen il-lenti f'post frisk u niexef, 'il bogħod mix-xemx diretta u minn temperaturi estremi.
- Jekk taħżen għal perjodi twal, ikkunsidra li tuża aġent tad-deumidifikazzjoni biex tipprevjeni t-tkabbir tal-moffa.
