Camera lens converters are primarily used to change the focal length of the lens, allowing photographers to achieve different perspectives and magnifications.

Teleconverters, also known as tele-extenders, are used to increase the focal length of a lens, resulting in a narrower field of view and higher magnification.

The main advantage of using a teleconverter is that it allows photographers to increase the focal length of their lens without having to purchase a new lens.

Wide-angle converters are designed to provide a wider field of view, allowing photographers to capture more of the scene in a single shot.

Macro converters are specifically designed to enable close-up photography, allowing photographers to capture detailed images of small subjects.

Fisheye converters are characterized by their extreme wide-angle and distorted perspective, creating a unique and exaggerated effect in images.

One of the main disadvantages of using a teleconverter is that it can potentially reduce the image quality, especially at higher magnification levels.

Teleconverters are frequently used in wildlife and sports photography to achieve a longer focal length and capture distant subjects.

The main advantage of using a wide-angle converter is that it allows photographers to capture a wider field of view, making it suitable for landscape and architectural photography.

Macro converters are often used in product and food photography to capture close-up and detailed images of small objects.

The main disadvantage of using a fisheye converter is the distorted perspective it creates, which can be desirable for certain creative effects but may not be suitable for all types of photography.

Wide-angle converters are frequently used in underwater photography to capture a wider field of view and accommodate the unique conditions of underwater environments.

Macro converters offer affordability and portability compared to dedicated macro lenses, making them a more accessible option for photographers who occasionally need close-up capabilities.

Teleconverters are often used in astrophotography to achieve a longer focal length and capture distant celestial objects.

Wide-angle converters may compromise image quality compared to dedicated wide-angle lenses, especially at the edges of the frame.
