Adjusting the focal length to achieve zoom: By moving the internal lens groups, the lens focal length can be changed, allowing flexible switching between wide-angle and telephoto. This meets the different needs of capturing close-up details and distant scenery without the need to change lenses. Control the framing range: Adjust the zoom level according to the shooting scene. Use the wide-angle end to expand the framing range, suitable for landscapes and group photos; use the telephoto end to narrow the framing range. Adaptable to various shooting scenarios: From everyday street photography and portrait photography to wildlife photography and action shots, the zoom component can adjust focal length to suit different scenes, reducing the hassle of carrying multiple lenses. Enhancing filming mobility: The integrated zoom design eliminates the need to frequently change lenses, avoiding dust entry and delays during lens changes. This enhances filming mobility in complex outdoor environments or fast-paced shooting scenarios. Control the perspective effect in the image: The wide-angle zoom end can enhance perspective, making the near objects appear larger and distant objects smaller, thereby increasing the visual impact; the telephoto zoom end weakens perspective, making the image more compact.
