For example, a 50mm lens is excellent for portraits, producing pleasing background blur (bokeh) and sharp subject focus. In comparison, a 35mm lens offers a wider field of view, making it ideal for capturing groups or more expansive scenes. Standard lenses generally perform well in a variety of lighting conditions, balancing size, weight, and image quality.
Wide-Angle and Telephoto Lenses
Wide-angle lenses typically range from 14mm to 35mm. They capture broader scenes, making them suitable for landscapes, architecture, and indoor photography. The expansive viewpoint adds depth and drama, allowing you to fit more elements into the frame. For example, a 24mm lens works well in cramped spaces, ensuring you capture all the details without distortion.
Telephoto lenses, on the other hand, range from 70mm to 300mm or more. These lenses excel at isolating subjects from a distance, making them perfect for wildlife, sports, and portrait photography. A 200mm lens lets you capture subjects without disturbing them, preserving natural behavior.
Both wide-angle and telephoto lenses emphasize different aspects of composition and perspective, allowing for creative expression through varied framing techniques.
How to Choose the Right Lens Size
Choosing the right lens size enhances your photography experience and improves image quality. Consider several factors, including your photography style and compatibility with your camera body.
Consider Your Photography Style
Identify your preferred photography style. Different styles require different lenses. For portrait photography, a standard lens like 50mm works well, creating natural-looking images. If you enjoy landscapes, opt for a wide-angle lens, such as a 24mm, to capture expansive views. For wildlife or sports, choose a telephoto lens (70mm or higher) to get close-up shots without disturbing the subjects. Assess the types of photography that excite you, and select a lens that complements that style.
