1. Увод

The Samyang 8mm f/3.5 Aspherical IF MC Fisheye lens is an ultra-wide angle lens designed for cameras with APS-C or smaller sensors. Its optical construction features 10 elements in 7 groups, including an aspherical hybrid lens. The lens incorporates a multilayer anti-reflection coating (UMC) to enhance optical performance, minimize flare, and reduce ghosting. The aperture consists of six diaphragm blades and can be set to f/22 for extensive depth-of-field. A built-in lens hood helps prevent unwanted light. This lens provides a 180-degree diagonal field of view, offering unique photographic perspectives.

5. Подешавање и инсталација

5.1 Причвршћивање објектива

1. Уверите се да је ваша камера искључена.
2. Remove the rear lens cap from the Samyang 8mm lens and the body cap from your camera.
3. Align the red index mark on the lens barrel with the corresponding red index mark on your camera's lens mount.
4. Уметните објектив у носач камере и окрените га у смеру казаљке на сату док не кликне на своје место. Немојте силом померати објектив.

5.2 Одвајање сочива

1. Уверите се да је ваша камера искључена.
2. While pressing the lens release button on your camera body, rotate the lens counter-clockwise until it stops.
3. Пажљиво уклоните објектив са носача камере.

6. Руковање објективом

6.1 Ручно фокусирање

This is a manual focus lens. To achieve sharp images, rotate the focus ring on the lens barrel until your subject appears clear in the viewfinder or on the camera's LCD screen. For fisheye lenses, a common technique is to set the focus to a specific distance (e.g., 1 meter or 3 feet) and rely on the extensive depth of field to keep most of the scene in focus, especially at smaller apertures.

6.2 Контрола отвора бленде

The lens features an aperture ring on the barrel. To control the aperture directly from your camera body (if supported), set the lens's aperture ring to its smallest aperture value (f/22). This allows the camera to electronically control the aperture setting. If your camera does not support electronic aperture control with this lens, you will need to adjust the aperture manually using the ring on the lens.

6.3 Подешавања експозиције

Since this is a manual lens, you may need to set your camera to Manual (M) or Aperture Priority (Av/A) mode. In Manual mode, you control both aperture (via the lens ring or camera, as described above) and shutter speed. In Aperture Priority mode, you set the aperture, and the camera automatically selects the appropriate shutter speed.

7. Одржавање и њега

7.1 Чишћење сочива

• Користите меку крпу која не оставља влакна или четкицу за објектив да бисте уклонили прашину са површина објектива.
• For smudges or fingerprints, apply a small amount of lens cleaning solution to a clean microfiber cloth and gently wipe the lens in a circular motion from the center outwards.
• Never use abrasive materials or harsh chemicals on the lens elements.

7.2 Складиштење

• Увек ставите предњи и задњи поклопац објектива када се објектив не користи.
• Чувајте сочиво на хладном и сувом месту, даље од директне сунчеве светлости и екстремних температура.
• Ако складиштите дуже време, размислите о употреби средства за одвлаживање како бисте спречили раст буђи.

КСНУМКС. Решавање проблема

8.1 Images are blurry or out of focus

• Ручно фокусирање: Ensure you are manually focusing correctly. Rotate the focus ring until your subject is sharp.
• Подешавања камере: Verify your camera is set to a manual focus mode.
• Дубина поља: At wider apertures (smaller f-numbers), the depth of field is shallower, requiring more precise focus. Try stopping down the aperture (larger f-number) to increase the depth of field.

8.2 Cannot control aperture from camera

• Aperture Ring Setting: For electronic aperture control via the camera, ensure the lens's aperture ring is set to its smallest aperture (f/22).
• Режим камере: Ensure your camera is in an appropriate mode (e.g., Aperture Priority or Manual) that allows aperture control.

8.3 Dark or underexposed images

• Подешавања експозиције: As this is a manual lens, the camera may not automatically set the correct exposure. Adjust your camera's ISO, shutter speed, or aperture to achieve proper exposure.
• Режим: Experiment with different metering modes on your camera.
