1. හැඳින්වීම

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.

6. කාචය ක්‍රියාත්මක කිරීම

6.1 අතින් අවධානය යොමු කිරීම

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 විවර පාලනය

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 නිරාවරණ සැකසුම්

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. නඩත්තුව සහ රැකවරණය

7.1 කාච පිරිසිදු කිරීම

• කාච මතුපිටින් දූවිලි ඉවත් කිරීම සඳහා මෘදු, ලින්ට් රහිත රෙද්දක් හෝ කාච බුරුසුවක් භාවිතා කරන්න.
• පැල්ලම් හෝ ඇඟිලි සලකුණු සඳහා, පිරිසිදු මයික්‍රෝෆයිබර් රෙද්දකට කාච පිරිසිදු කිරීමේ ද්‍රාවණය කුඩා ප්‍රමාණයක් යොදන්න, ඉන්පසු කාචය මැද සිට පිටතට රවුම් චලිතයකින් මෘදු ලෙස පිස දමන්න.
• Never use abrasive materials or harsh chemicals on the lens elements.

7.2 ගබඩා කිරීම

• කාචය භාවිතයේ නොමැති විට සෑම විටම ඉදිරිපස සහ පසුපස කාච ආවරණ සවි කරන්න.
• කාචය සෘජු හිරු එළියෙන් සහ අධික උෂ්ණත්වයන්ගෙන් ඈත්ව සිසිල් වියළි ස්ථානයක ගබඩා කරන්න.
• දිගු කාලයක් ගබඩා කරන්නේ නම්, අච්චු වර්ධනය වැළැක්වීම සඳහා තෙතමනය අඩු කරන කාරකයක් භාවිතා කිරීම සලකා බලන්න.

8. දෝශ නිරාකරණය

8.1 Images are blurry or out of focus

• අතින් අවධානය: Ensure you are manually focusing correctly. Rotate the focus ring until your subject is sharp.
• කැමරා සැකසුම්: Verify your camera is set to a manual focus mode.
• ක්ෂේත්රයේ ගැඹුර: 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).
• කැමරා මාදිලිය: Ensure your camera is in an appropriate mode (e.g., Aperture Priority or Manual) that allows aperture control.

8.3 Dark or underexposed images

• නිරාවරණ සැකසුම්: 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.
• මිනුම් මාදිලිය: Experiment with different metering modes on your camera.
