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).
