Përdorimi i lentes
Rregullimi i hapjes
The aperture is controlled directly on the lens using the aperture ring. Rotate the ring to select your desired f-stop. A wider aperture (smaller f-number like F1.8) allows more light and creates a shallower depth of field, ideal for portraits. A narrower aperture (larger f-number) allows less light and creates a deeper depth of field, suitable for landscapes.
Fokusimi manual
To focus, rotate the focus ring on the lens barrel until your subject appears sharp in the viewfinder or on the LCD screen. Utilize your camera's focus peaking and magnification features for precise focusing, especially at wider apertures.
- Përqendrimi maksimal: Highlights in-focus areas with a colored outline.
- Zmadhuar View: Zooms in on a portion of the image for critical focus assessment.
Mirëmbajtja
Pastrimi i lenteve
- Use a soft, lint-free microfiber cloth specifically designed for optical surfaces to clean the front and rear elements.
- Për njollat kokëforta, aplikoni një sasi të vogël të tretësirës për pastrimin e lenteve në leckë, jo direkt në lente.
- Use a blower brush to remove dust particles before wiping to prevent scratching.
- Asnjëherë mos përdorni materiale gërryese ose kimikate të ashpra.
Magazinimi
- Vendosni gjithmonë kapakët e përparmë dhe të pasmë të lentes kur lentet nuk janë në përdorim.
- Ruajeni lenten në një vend të freskët dhe të thatë, larg rrezeve të diellit direkte dhe temperaturave ekstreme.
