Choosing the right lens for portrait photography can feel overwhelming, especially when you’re just starting out. The focal length of your lens dramatically impacts how your subject looks, how much background you capture, and the overall mood of your portrait. Whether you’re shopping for your first portrait lens or looking to expand your kit, understanding how focal length affects your images is essential for creating stunning portraits.
Focal length, measured in millimeters (mm), determines how much of the scene your camera captures and how your subject appears in the frame. The lower the number, the wider the angle. The higher the number, the narrower the angle. This seemingly simple measurement has a profound effect on portrait photography.
The key to understanding focal length lies in recognizing that it’s not just about magnification—it’s about perspective. Different focal lengths change how facial features appear, affect background compression, and determine your working distance from your subject. A simple rule of thumb for portrait photography is that, if you use a short focal length, step back and include more background in the frame to avoid distorting your subject’s features.
Wide-angle lenses capture more of the scene around your subject, making them excellent for environmental portraits where the background adds context to your story. Use a 35mm for environmental portraits. These will be more full length portraits where the subject is smaller and doesn’t fill the frame.

However, wide-angle lenses come with challenges for portrait work. Wider angle focal lengths, anywhere from 16-35mm can heavily distort your subject’s appearance. This distortion becomes more pronounced when subjects are placed toward the edges of the frame or when you get too close.
Best for:
The 50mm lens is often called the “nifty fifty” because it offers a natural perspective, similar to what the human eye sees, making them versatile for various types of portraits. This focal length strikes a balance between environmental context and subject isolation.

A 50mm lens is a good portrait lens for full length photos or taken from the waist up. If the portrait is any closer, make sure that your subject is towards the middle of the frame with space around them to avoid distortion. The 50mm lens is particularly forgiving for beginners because it provides a familiar perspective that’s easy to work with.
Best for:
Generally speaking, the best focal length for portraits is 85mm. This focal length range is considered the gold standard for portrait photography, and for good reason. For close up portraits, a focal length of 85mm and up is ideal, and an 85mm is arguably the most used portrait lens no matter the genre of the industry.

The 85mm focal length provides several advantages:
For even tighter headshots, 135mm lenses offer further compression of features while maintaining excellent image quality and subject separation.
Best for:
Longer focal lengths offer extreme background compression and allow you to work from a considerable distance. While not common for everyday portrait work, they can create unique artistic effects and are useful in situations where you need to maintain distance from your subject.

When selecting a portrait lens, consider these key factors:
A fast maximum aperture denotes an aperture of f/4.0 or wider. The faster the lens is, the shallower the depth of field and the ability of the lens to blur the background. For beautiful bokeh and subject separation, look for lenses with wide apertures like f/1.4, f/1.8, or f/2.8.
Prime lenses offer faster apertures and sharper performance across the frame while remaining relatively small and lightweight. On the other hand, zoom lenses tend to be slower and are often larger and heavier. However, they provide greater versatility because you can change your focal length on the fly.
Popular zoom option is 70-200mm zoom lens. This range covers most desired focal lengths for portrait work, allowing you to reframe your composition and adjust foreground-background compression quickly without moving an inch.
Consider how close you want to be to your subject. If you want a full length shot and you don’t want to be too far away, go with a 50mm focal length. With an 85mm focal length you’ll have to stand further away. Some photographers prefer the intimacy of working closer with a 50mm, while others like the comfortable distance an 85mm provides.
When evaluating focal length comparison photos, pay attention to several key differences:
Facial Proportions: Wide-angle lenses can make noses appear larger and faces wider, while longer focal lengths create more flattering, natural proportions.
Background Compression: Longer focal lengths compress the background, making distant objects appear larger and closer to your subject.
Perspective Distortion: When choosing a lens for portraits you need to think about your subject. You might need to be closer to be more connected to your subject. The trade-off is that closer working distances can introduce perspective distortion.
