Kenko 2X Teleplus DG Auto Focus Teleconverter (MC4-AF2.0DGX-C) Instruction Manual

1. పరిచయం

A teleconverter is an optical accessory designed to increase the focal length of a primary lens. It is mounted between the camera body and the lens. The Kenko 2X Teleplus DG Auto Focus Teleconverter, model MC4-AF2.0DGX-C, effectively doubles the focal length of your attached lens, allowing for closer magnification of distant subjects. This model features a computer-designed 4-element optical system for enhanced performance.

2. ఉత్పత్తి ముగిసిందిview

The Kenko 2X Teleplus Teleconverter is a compact unit equipped with optical elements and electronic contacts on both sides. These contacts facilitate communication between the camera body and the attached lens, ensuring that auto-exposure and auto-focus functions are maintained where supported by the camera and lens combination.

When using the Kenko 2X Teleplus Teleconverter, it is important to understand its impact on your camera's performance:

• Focal Length Magnification: The 2X teleconverter doubles the focal length of your attached lens. For example, a 50mm lens becomes a 100mm lens, and a 300mm lens becomes a 600mm lens.
• Light Loss: The use of a 2X teleconverter results in a loss of two stops of light. This means an f/2.8 lens will effectively become an f/5.6 lens, and an f/5.6 lens will become an f/11 lens. Adjust your camera's ISO or shutter speed accordingly to compensate for this light reduction.
• Autofocus Performance: Most camera bodies are designed to maintain autofocus up to an effective aperture of f/5.6. If the combined lens and teleconverter result in an effective aperture smaller than f/5.6 (e.g., f/8 or f/11), the camera's autofocus system may struggle or fail to achieve focus. In such situations, switching to manual focus is recommended for precise focusing.
• చిత్ర నాణ్యత: While teleconverters extend focal length, they can sometimes introduce a slight reduction in overall image sharpness or contrast, particularly when used with lenses that are not prime or in challenging lighting conditions. For best results, use a sturdy tripod and ensure optimal lighting.

5. నిర్వహణ మరియు సంరక్షణ

Proper care will ensure the longevity and performance of your teleconverter:

• క్లీనింగ్ ఆప్టిక్స్: Use a soft, lint-free microfiber cloth specifically designed for optical surfaces to gently clean the glass elements. For stubborn smudges, a small amount of lens cleaning fluid applied to the cloth (not directly to the lens) can be used.
• Cleaning Contacts: Periodically clean the electronic contacts on both sides of the teleconverter with a clean, dry cotton swab to ensure reliable communication with your camera and lens. Avoid touching the contacts with your fingers.
• నిల్వ: Always attach the front and rear caps when the teleconverter is not in use to protect the optical elements and contacts from dust and damage. Store the teleconverter in a dry, cool environment, away from direct sunlight and extreme temperatures.
• నిర్వహణ: Avoid dropping or subjecting the teleconverter to strong impacts, as this can damage the internal optical alignment.

If you encounter issues with your Kenko 2X Teleplus Teleconverter, consider the following:

• ఆటో ఫోకస్ పనిచేయకపోవడం:
  • Check the effective aperture of your lens with the teleconverter. If it is f/8 or smaller, your camera's autofocus system may not function. Switch to manual focus.
  • Ensure the teleconverter and lens are securely mounted and that all electronic contacts are clean and free of debris.
  • Verify that your camera's autofocus mode is correctly set.
• Soft or Blurry Images:
  • Ensure proper focus. If using manual focus, confirm critical focus.
  • Check for camera shake, especially with longer effective focal lengths. Use a tripod or increase shutter speed.
  • Verify that the lens and teleconverter optics are clean.
• ఎక్స్‌పోజర్ సమస్యలు:
  • Remember the two-stop light loss. Adjust ISO or use a wider aperture (if available) to compensate.
  • Ensure your camera's metering mode is appropriate for the scene.
