6. Använda objektivet

6.1 Manuell fokusering

The Irix 11mm f/4.0 Firefly is a manual focus lens. Rotate the focus ring to adjust the focus. The built-in AE chip provides focus confirmation through your camera's viewhitta eller live view, indicating when your subject is in sharp focus.

6.2 Infinity Click

The lens features an audible and tactile 'infinity click' that helps you quickly set the focus to infinity without needing to look at the focus scale. This is particularly useful for astrophotography or landscape shots where distant subjects need to be sharp.

6.3 Hyperfocal Scale

Utilize the hyperfocal scale on the lens barrel to maximize depth of field. By setting the focus to the hyperfocal distance, you can achieve sharp focus from half that distance to infinity.

6.4 Bländarkontroll

Thanks to the built-in AE chip, the aperture of the Irix 11mm f/4.0 Firefly lens can be controlled directly from your camera body, just like an autofocus lens. This allows for seamless integration with your camera's exposure modes.

7. Underhåll

7.1 Rengöring av linsen

• Använd en blåsborste för att ta bort damm från linsytan.
• 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.
• Never apply cleaning solution directly to the lens element.
• Clean the lens mount contacts with a dry, soft cloth if necessary.

7.2 Förvaring

• Sätt alltid på det främre och bakre linsskyddet när objektivet inte används.
• Förvara linsen på en sval, torr plats, borta från direkt solljus och extrema temperaturer.
• If storing for an extended period, consider using a dehumidifying agent to prevent mold growth.
