ADAPTER WIDE 2X PROF 43M
ADAPTER WIDE 2X PROF 43M Overview
Overview and Features
Type: Teleconverter: Despite the name "WIDE," a "2x" adapter is a teleconverter. Its purpose is to double the focal length of the lens it's attached to. For example, when attached to a 50mm lens, it turns it into a 100mm lens. This is useful for getting closer to a subject without physically moving.
43mm Filter Thread: The "43M" in the name refers to the 43mm filter thread on the back of the adapter. This means it is designed to screw onto a lens that has a 43mm front filter thread.
Construction: These adapters are typically made of multiple optical glass elements with anti-reflective coatings to minimize flare and ghosting. They are often encased in a metal or plastic barrel.
Functionality:
Magnification: It magnifies the image, allowing you to capture distant subjects.
Autofocus Compatibility: Most modern adapters of this type are compatible with a camera's autofocus system, although performance may be slower than a native lens.
Versatility: They are a cost-effective way to add a telephoto capability to a lens kit without buying a dedicated telephoto lens.
Limitations:
Image Quality: As a third-party accessory, a 2x teleconverter may introduce some image degradation, such as a loss of sharpness, increased chromatic aberration, or vignetting, especially at the edges of the frame.
Light Loss: A teleconverter will reduce the amount of light that reaches the sensor. A 2x converter typically results in a loss of about 2 stops of light.
In summary, the "ADAPTER WIDE 2X PROF 43M" is a teleconverter, not a wide-angle lens. It is designed to double the focal length of a lens with a 43mm front thread. It serves as an economical and versatile way to extend the reach of your camera's lens, especially for camcorders and smaller mirrorless cameras.
