An 85mm lens is a classic portrait length because it flatters faces and lets you stand at a comfortable distance. A 50mm lens is more versatile, works in smaller spaces, and shows more of the setting. Your room size and style decide which suits you.
Perspective and Working Distance
Focal length changes how far you stand from a subject to get the same framing. With a head-and-shoulders shot, an 85mm needs you further back than a 50mm does. Standing further away tends to flatten facial features slightly, which many people find flattering.
With a 50mm you work closer, which can feel more intimate and conversational, but features near the lens can look more prominent if you get very close.
Space and Background
- Small studio or living room: 50mm fits, while 85mm may force you against a wall.
- Outdoors with room to move: 85mm gives strong subject separation.
- Environmental portraits: 50mm shows more of the person’s surroundings.
- Background blur: 85mm compresses the background and enlarges it, so it looks softer at the same aperture.
At a Glance
| Question | 50mm | 85mm |
|---|---|---|
| Room needed | Less | More |
| Look | Natural, contextual | Flattering, isolated |
| Full-length shots | Easier | Needs more distance |
| General use | Very flexible | More specialised |
Making the Call
- Measure your usual shooting space. If you cannot step back several metres, favour 50mm.
- Decide whether you want portraits that show place or ones that isolate the person.
- Think about other uses: a 50mm also handles street and everyday scenes.
- If you own a smaller-sensor camera, remember the crop factor makes both lenses appear longer.
Working With Your Subject
Distance affects communication as well as optics. At 85mm you may stand several metres away, so giving directions can mean raising your voice or using gestures. A 50mm keeps you within easy conversation range, which helps relaxed, natural expressions, especially with children or nervous subjects.
On the other hand, some people feel more at ease when the camera is not close to their face, and the longer lens respects that space. Think about the people you photograph most often and how they react to a camera.
- Fast-moving children: 50mm keeps them closer and easier to follow.
- Formal headshots: 85mm gives a polished, classic look.
- Couples and small groups: 50mm fits more people in the frame.
FAQ
Is 85mm too long for indoor use?
It can be. In a small room you may not have the distance for full-body shots, though head-and-shoulders portraits often work well.
Can I use 50mm for professional portraits?
Yes. Many photographers use it for portraits, especially environmental ones. It is a matter of style and space, not a rule about professionalism.
The Short Version
Choose 85mm when you have space and want flattering, portraits with clean backgrounds. Choose 50mm for flexibility, tight spaces and wider storytelling. Many photographers eventually own both.
