Wide-angle lenses have a shorter focal length and a wider field of view than standard lenses. They are ideal for capturing expansive scenes like landscapes, cityscapes, and interiors. However, wide-angle lenses can distort subjects if they are too close to the lens, making objects appear disproportionately large.
- Focal Length: Wide-angle lenses typically have a focal length of less than 35mm in a 35mm film or full-frame sensor format.
- Field of View: These lenses offer an extensive field of view, often between 64° and 84°, making them excellent for capturing broad scenes.
- Versatility: These lenses are popular for capturing everything from expansive landscapes and cityscapes to confined interiors.
- Depth: They create an exaggerated sense of depth and can make the foreground appear closer relative to the background.
Challenges and Pitfalls
- Distortion: Wide-angle lenses can create barrel distortion, where straight lines curve outward from the center of the image.
- Proportional Distortion: Objects close to the lens can appear disproportionately large compared to those farther away.
- Landscape Photography: Capture more of the sky and ground in a single frame.
- Architectural and Interior Photography: Capture the breadth of a room or building façade.
- Street Photography: Incorporate more contextual elements without stepping back.
- Perspective Control: Tilting the lens slightly can help in managing distortion to some extent.
- Hyper-focal Distance: Using the hyper-focal distance can maximize the depth of field, making both near and far objects appear in focus.
- Lens Correction Algorithms: Modern cameras and post-processing software often include settings to correct the distortion caused by wide-angle lenses.
