What is considered a wide angle lens in relation to a normal lens for a specific format?

1. Longer focal length

2. Equal focal length

3. Smaller focal length

4. Variable focal length

The correct answer is: Smaller focal length

A wide-angle lens is characterized by a smaller focal length compared to a normal lens for a specific camera format. For instance, in a full-frame format, a normal lens typically has a focal length around 50mm, while a wide-angle lens might fall within the range of 14mm to 35mm. The smaller focal length allows for a wider field of view, enabling photographers to capture more of the scene in a single frame, which is particularly useful in landscape and architectural photography. The distinction in focal lengths is crucial because it directly impacts the perspective and composition of the photographed scene. Wide-angle lenses also introduce specific characteristics, such as greater depth of field and potential distortion, which can be creatively employed in various photographic contexts. Understanding the relationship between focal lengths helps photographers choose the appropriate lens for their creative vision and the specific needs of their shots.
