Supplementary Lens

Supplementary lenses, also known as auxiliary lenses or add-on lenses, are additional optical attachments that can be used with cameras or smartphones to enhance their photographic capabilities. These lenses are designed to be attached to the existing lens of the device, either by screwing onto the front of the lens or by using a clip-on mechanism.

Supplementary lenses come in various types, each serving a specific purpose:

1. Wide-angle lens: This lens has a shorter focal length than the built-in lens, allowing you to capture a wider field of view. It is useful for landscape photography, architecture, and group shots where you want to fit more into the frame.

2. Telephoto lens: This lens has a longer focal length than the built-in lens, enabling you to zoom in and capture distant subjects with more detail. It is ideal for wildlife photography, sports events, and portrait photography where you want to isolate the subject from the background.

3. Macro lens: This lens is designed for close-up photography, allowing you to capture intricate details of small subjects like flowers, insects, or jewelry. It provides a high level of magnification and enables you to focus at a very short distance from the subject.

4. Fisheye lens: This lens creates a unique and distorted perspective, capturing an extremely wide-angle view with a curved effect. It is often used for creative and artistic purposes, such as capturing immersive landscapes or creating a unique visual style.

Supplementary lenses are typically affordable and portable, making them a popular choice for photographers who want to expand their creative options without investing in expensive camera equipment. However, it's important to note that the quality of the images produced by supplementary lenses may vary depending on the brand and price range.
