4. Funcionament de l'objectiu
4.1 Enfocament manual
The lens features a manual focus ring. Rotate this ring to achieve sharp focus on your subject. For precise macro photography, utilize your camera's focus peaking or magnification assist functions, which are typically found in your camera's shooting settings.
4.2 Control d'obertura
The lens has a manual aperture ring. Rotate this ring to select your desired aperture from F2.8 to F16. A wider aperture (e.g., F2.8) allows more light and creates a shallower depth of field, resulting in blurred backgrounds (bokeh). A narrower aperture (e.g., F16) increases depth of field, keeping more of the scene in focus.
4.3 1:1 Macro Magnification
This lens offers a 1:1 magnification ratio, allowing you to capture subjects at life-size on your camera's sensor. The closest focusing distance is 0.17 meters (0.56 feet). When shooting at high magnifications, even slight camera movement can cause blur. Using a tripod is highly recommended for stable and sharp macro images.

6. Manteniment
6.1 Lens Care and Cleaning

6.2 Emmagatzematge

7. Solució De Problemes
7.1 Camera Not Recognizing Lens
If your camera displays an error message or does not recognize the lens, ensure that the "Release shutter without lens" or "Shoot without lens" setting is enabled in your camera's menu. Consult your camera's manual for specific instructions on this setting.
7.2 Les imatges apareixen borroses
- Focus: Verify that the lens is properly focused. This is a manual focus lens, so precise adjustment of the focus ring is essential. Utilize your camera's focus aids.
- Tremolor de la càmera: For macro photography, camera shake is a common cause of blur. Use a tripod and a remote shutter release or timer to minimize movement.
- Velocitat d'obturació: Ensure your shutter speed is fast enough to freeze motion and reduce blur, especially in handheld shooting.
- Neteja de les lents: Ensure the lens elements are clean and free from dust or smudges.
