Handvirkur fókus:
- Skoðaðu í gegnum myndavélina þína viewfinnandi.
- 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.
Ljósopsstýring:
- Snúðu ljósopshringnum til að velja þá f-stop sem þú vilt.
- 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.
Dýpt sjónsviðs:
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. Viðhald og umönnun
Rétt viðhald tryggir endingu og bestu mögulegu virkni linsunnar.
Þrif á linsunni:
- Linsuþættir: 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.
