The Vivitar Automatic Tele Converter Lens 2x-21 for Olympus is an optical accessory designed to increase the focal length of Olympus SLR camera lenses. Here’s an overview of what this typically entails:
-
Tele Converter: A tele converter, also known as a telephoto converter or extender, is an optical device that mounts between the camera body and the lens. Its primary function is to magnify the image produced by the lens, effectively increasing the focal length.
-
2x Magnification: The "2x" indicates that this tele converter doubles the focal length of the lens it is attached to. For example, if you have a 100mm lens and attach the 2x tele converter, it effectively turns it into a 200mm lens (100mm × 2).
-
Automatic Functionality: The term "Automatic" in the product name suggests that it supports automatic functions such as automatic aperture control and metering through electrical contacts. This allows for seamless integration with Olympus SLR cameras without the need for manual adjustments for exposure.
-
Compatibility with Olympus: The tele converter is specifically designed to be used with Olympus OM-system lenses and cameras. It ensures proper communication between the camera body and the lens, enabling automatic functions and maintaining image quality.
-
Purpose: Tele converters are commonly used in wildlife photography, sports photography, and any situation where additional reach is needed without carrying multiple large telephoto lenses. They provide a cost-effective way to extend the focal length range of existing lenses
