The short answer
There is no single best lens for portraits, but a prime lens of around 85mm on a full-frame camera is the most commonly recommended choice. Focal lengths between roughly 50mm and 135mm cover most portrait work. Within that range, the right lens depends on your space, your sensor size, your budget and the kind of portraits you shoot.
What focal length does to a portrait
Focal length changes more than how much of the scene you capture. It affects how a face looks, because it determines how close you stand.
- Wide lenses used close up exaggerate whatever is nearest the camera. Noses can look larger and faces may look distorted. This can be used for effect, but it is rarely flattering by default.
- Short telephoto lenses (around 85mm to 135mm) let you stand further back for the same framing. Features look more natural, and backgrounds look more compressed and are easier to blur.
- Longer lenses compress further and allow comfortable distance, but need space and make conversation harder.
These descriptions refer to full-frame equivalents. On cropped-sensor cameras (APS-C), multiply the focal length by about 1.5 (or 1.6 for many Canon bodies) to get an approximate equivalent field of view. A 50mm lens on APS-C then behaves like a short telephoto, around 75mm to 80mm equivalent in framing.
Popular portrait focal lengths compared
85mm: the usual first recommendation
Often described as the classic portrait focal length. It frames head-and-shoulders and half-length shots comfortably, gives flattering proportions, and is easy to blur backgrounds with. Fast versions at f/1.8 and f/1.4 are available for many camera systems, and some premium versions open to f/1.2. The drawback is that you need room to work, and in small indoor spaces it can feel tight.
50mm: the versatile option
A 50mm f/1.8 is inexpensive for many systems and light enough to carry all day. It is a good choice for half-length and full-length portraits and for tight spaces. For tight headshots you will be quite close, which may slightly exaggerate features. If you can only buy one lens and shoot varied subjects, 50mm is a sensible choice. It also answers a common question: is 50mm or 85mm better for portraits? Neither is better in general. 85mm gives more compression and blur, while 50mm is more flexible and works in tighter spaces.
35mm: for environmental portraits
Wider lenses such as 35mm are popular for environmental and lifestyle portraits, where the setting matters. Keep subjects away from the edges of the frame, where stretching is more noticeable, and be careful about the distance to the face.
24mm: special effect, not default
A 24mm lens can be used for dramatic environmental portraits, with the subject small in a large scene, or for creative close-ups. It is more demanding to use for flattering faces. For most people, 50mm is a more comfortable portrait choice than 24mm.
105mm to 135mm: compression and distance
These longer primes give strong background separation and are well suited to headshots, outdoor portraits and shooting from a distance. They may be heavier and require more space.
70-200mm zoom: flexibility
A 70-200mm f/2.8 zoom is a favourite of many working photographers for events, weddings and sessions where you cannot move easily. It covers several focal lengths in one lens, which is practical, but it is heavier and typically costs more than a single prime. Its widest aperture of f/2.8 gives good but not extreme background blur.
Primes versus zooms
- Primes generally offer wider maximum apertures, lighter weight and often excellent sharpness for the price. They make you move your feet.
- Zooms give flexibility, which is helpful when you cannot easily change position, such as at events.
Neither is “correct”. Many photographers carry one of each.
Aperture: how much do you need?
A wide maximum aperture (f/1.8 or f/1.4) helps with background blur and low light, but those lenses cost more and have a razor-thin depth of field, so focus accuracy matters. An aperture of f/2.8 is a good balance. Do not assume wider is always better: at f/1.2 or f/1.4, a slight focus error can leave the eyes soft, and some sharpness trade-offs exist wide open. For help with focus, see eyes and emotion in portrait photography.
Choosing based on your situation
| Situation | Sensible starting choice |
|---|---|
| First portrait lens, tight budget | A 50mm f/1.8 (or the equivalent for your system) |
| Headshots and flattering close-ups | An 85mm or longer prime |
| Small rooms and home studios | 35mm or 50mm |
| Events, weddings, moving around | 70-200mm zoom |
| Environmental portraits | 35mm to 50mm |
| Crop sensor camera | Roughly 35mm for a 50mm look, 50-56mm for an 85mm look |
Specific models change quickly, and many camera brands offer excellent options as well as third-party alternatives. Check recent reviews and make sure any lens you consider is compatible with your camera mount.
Practical tips
- Pick one lens and learn it well. Skill with a single lens matters more than owning several.
- Rent before you buy if you are considering an expensive lens.
- Check your working space. An 85mm can be hard to use in a small apartment.
- Mind your shutter speed. Longer lenses need faster shutter speeds to avoid camera shake. See choosing the right shutter speed for portrait photography.
- Consider the angle too. Lens choice and camera angle work together, as discussed in portrait poses and camera angles.
