Focal Length and Aperture Impact
When the 1.4x Teleconverter TC-1401 is attached, the focal length of your lens will be multiplied by 1.4. For example, a 100mm lens will become a 140mm lens. Concurrently, the maximum aperture of the lens will decrease by one stop. For instance, an f/2.8 lens will become an f/4 lens.
Автофокус функциясы
The TC-1401 supports autofocus (AF) functionality with compatible lenses and camera bodies, typically up to a maximum aperture of F8. If the combined maximum aperture of your lens and teleconverter is narrower than F8, autofocus performance may be reduced or unavailable. In such cases, manual focus may be necessary.
Жалпы пайдалануу боюнча кеңештер
- Жарыктандыруу: Due to the reduction in maximum aperture, the teleconverter performs best in well-lit conditions. In low light, you may need to increase ISO or use a slower shutter speed.
- Туруктуулук: For optimal sharpness, especially at extended focal lengths, using a sturdy tripod or monopod is highly recommended.
- Жабык ылдамдыгы: To counteract camera shake at longer focal lengths, use a faster shutter speed. The general rule of thumb is to use a shutter speed equal to or faster than 1/effective focal length (e.g., for a 600mm effective focal length, use 1/600s or faster).

Проблемаларды чечүү
Автофокус маселелери
- Көйгөй: Autofocus is slow or does not engage.
Чечим: Check if the combined maximum aperture is F8 or wider. In dimmer conditions or with narrower apertures, autofocus performance may be limited. Ensure the lens and teleconverter are securely mounted and electrical contacts are clean.
Image Quality Degradation
- Көйгөй: Images appear soft or lack sharpness.
Чечим: Ensure the teleconverter is used with a compatible Sigma Global Vision lens. Verify that the lens and teleconverter elements are clean. Use a tripod or increase shutter speed to minimize camera shake. Optimal image quality is achieved in good lighting conditions.
Mounting Problems
- Көйгөй: Teleconverter does not attach securely to the camera or lens.
Чечим: Ensure correct alignment of mounting indexes. Do not force the attachment. Check for any obstructions or damage to the mounts on the camera, teleconverter, or lens.
