6. Funcionament de l'objectiu
6.1 Enfocament manual
This is a manual focus lens. To achieve sharp images:
- Set your camera to Manual Focus (MF) mode.
- Mira a través del viewfinder or use the camera's LCD screen.
- Rotate the focus ring on the lens until your subject appears sharp. Many modern cameras offer focus peaking or magnification aids to assist with manual focusing. Refer to your camera's manual for these features.
- For fisheye lenses, due to their wide depth of field, precise focusing is often less critical, especially at smaller apertures (higher f-numbers) and for distant subjects. The minimum focusing distance is approximately 0.3 meters.
6.2 Manual Aperture Control
The aperture (f-stop) is controlled directly on the lens:
- Rotate the aperture ring on the lens to select your desired f-stop (e.g., f/3.5, f/5.6, f/8, etc.).
- A smaller f-number (e.g., f/3.5) indicates a wider aperture, allowing more light and creating a shallower depth of field.
- A larger f-number (e.g., f/22) indicates a narrower aperture, allowing less light and creating a greater depth of field.
- Your camera should be set to a manual exposure mode (M) or aperture priority mode (A) to properly utilize the manual aperture control.
6.3 Understanding Fisheye Perspective
This 8mm fisheye lens produces a distinct barrel distortion and a 180° angle of view. Straight lines not passing through the center of the image will appear curved. This effect is inherent to fisheye lenses and is used for creative purposes. Experiment with different compositions to achieve unique results.
7. Manteniment
7.1 Neteja de la lent
- Cos de la lent: Use a soft, clean cloth, slightly dampened with water or a mild cleaning solution, to wipe the exterior of the lens.
- Elements de la lent:
- First, use a blower brush to remove any loose dust or particles.
- If smudges or stubborn dirt remain, apply a small amount of lens cleaning fluid to a clean lens cleaning cloth (microfiber) and gently wipe the lens surface in a circular motion from the center outwards.
- Never apply cleaning fluid directly to the lens surface.
7.2 Emmagatzematge
- Col·loqueu sempre les tapes frontal i posterior de l'objectiu quan no l'utilitzeu.
- Store the lens in a cool, dry place, away from direct sunlight and high humidity.
- If storing for extended periods, consider using a dehumidifying agent or a dry cabinet to prevent mold growth.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Images are blurry/out of focus. | Incorrect manual focus. | Ensure your camera is set to MF mode. Use focus peaking or magnification on your camera to assist with precise focusing. Rotate the focus ring until the subject is sharp. |
| Images are too dark or too bright. | Incorrect aperture setting or exposure. | Adjust the aperture ring on the lens. Ensure your camera's exposure settings (shutter speed, ISO) are appropriate for the lighting conditions and chosen aperture. Use your camera's light meter. |
| Lens cannot be attached/detached. | Misalignment or lens release button not pressed. | Ensure the mounting index marks are aligned. For detachment, firmly press the lens release button on the camera body while rotating the lens. Do not force. |
