Telesor Auto 2x Tele converter(CA)

The Telesor Auto 2x Tele Converter (CA) is an accessory designed to double the effective focal length of compatible lenses while maintaining automatic diaphragm control. Here's a detailed overview of its features, performance considerations, and usage tips:

Key Features:

1. Compatibility: Designed for use with CA mount lenses, commonly used with certain camera systems. Ensure you have the correct mount version for your camera.
2. Magnification: Provides 2x magnification, effectively doubling the focal length of the attached lens. For instance, a 100mm lens will act as a 200mm lens when used with this teleconverter.
3. Automatic Diaphragm Control: Maintains automatic diaphragm functionality, allowing for seamless use with automatic exposure settings.

Performance Considerations:

1. Image Quality: Like most teleconverters, the Telesor Auto 2x can introduce some loss in image quality, including reduced sharpness and contrast. The extent of this degradation depends on the quality of both the teleconverter and the primary lens.
2. Aperture Reduction: The teleconverter reduces the maximum aperture of the lens by two stops. For example, a lens with a maximum aperture of f/2.8 will effectively become f/5.6.
3. Autofocus Performance: Autofocus speed and accuracy may be affected, especially in low-light conditions or with lenses that have smaller maximum apertures.

Practical Tips:

1. Check Compatibility: Ensure your primary lens is compatible with the teleconverter. Some lenses, particularly those with wide angles or smaller apertures, may not perform optimally.
2. Use a Tripod: To minimize camera shake, which can be more pronounced with the increased focal length, use a tripod or other stable support.
3. Optimize Aperture: Stopping down the aperture slightly (e.g., from f/5.6 to f/8) can help improve image sharpness and contrast when using the teleconverter.
4. Test Your Setup: Test the teleconverter with your specific lens and camera combination to understand its impact on image quality and to fine-tune your shooting technique.
