3.2 Keserasian Kamera

These lenses are designed for Z Mount APS-C cameras. When used with full-frame Z Mount cameras, it is recommended to switch to APS-C/S35 mode to avoid vignetting. Image quality may be compromised in crop mode if not properly configured.

4. Operating the Lenses

4.1 Autofocus Operation

The SIRUI Sniper lenses feature a fast and accurate autofocus system. Ensure your camera's autofocus mode is set appropriately (e.g., AF-C for continuous, AF-S for single shot). The STM motor provides quiet operation, beneficial for video recording.

4.2 Kawalan Apertur

The F1.2 maximum aperture allows for significant light gathering and shallow depth of field. For sharper images, especially when shooting wide open, consider stopping down to around F5.6. The lenses maintain consistent color tone across all focal lengths.

5. Penyelenggaraan

5.1 Membersihkan Kanta

• Use a blower brush to remove dust and loose particles from the lens surface.
• For smudges or fingerprints, use a clean microfiber cloth specifically designed for optics, along with a lens cleaning solution.
• Avoid using harsh chemicals or abrasive materials that could damage the lens coatings.

5.2 Penyimpanan

• Store lenses in a cool, dry place away from direct sunlight and extreme temperatures.
• Always use the provided lens caps and the storage bag to protect the lenses from dust and physical damage.

6. Penyelesaian masalah

6.1 Soft Images at Wide Aperture

At F1.2, lenses can sometimes appear softer, especially at the edges. This is a characteristic of very fast lenses. To achieve maximum sharpness, stop down the aperture to F2.8 or smaller (e.g., F5.6).

6.2 Vignetting on Full-Frame Cameras

These are APS-C lenses. If used on a full-frame camera, vignetting (darkening at the corners of the image) may occur. To mitigate this, activate the APS-C/S35 crop mode in your camera settings or perform post-editing to crop the image.

6.3 Isu Autofokus

If autofocus is not performing as expected, ensure:

• The lens is securely mounted to the camera.
• Camera firmware and lens firmware are up to date.
• There is sufficient light for the autofocus system to operate effectively.
• The subject has enough contrast for the camera to lock focus.
