Wide vs ultra-wide vs telephoto: which phone lens to use
Most phones have two to four cameras on the back, and they're good at very different things. Here's what each lens is for, how they compare, and why your 3x shot sometimes isn't really the 3x lens.
The three lenses, briefly
- Main (wide, "1x"). Usually the biggest sensor and the brightest lens on the phone. It's the best in low light and has the most detail.
- Ultra-wide ("0.5x" or "0.6x"). Fits much more into the frame, for landscapes, architecture and small rooms. It usually has a smaller sensor, and it stretches things near the edges of the frame.
- Telephoto ("2x", "3x", "5x" and up). Brings distant things closer and flattens perspective, which suits portraits. Longer telephotos often use a "periscope" design. Most have smaller sensors than the main camera.
Side by side
| Ultra-wide | Main | Telephoto | |
|---|---|---|---|
| Typical zoom label | 0.5x to 0.6x | 1x | 2x to 10x |
| Rough full-frame equivalent | 13 to 16 mm | 23 to 28 mm | 48 to 240 mm |
| Low light | Weakest | Best | Weaker than main |
| Edge distortion | Noticeable | Low | Very low |
| Best for | Landscapes, interiors, groups | Almost everything | Portraits, details, distant subjects |
Exact numbers vary a lot between phones. Check your own phone's specs for its focal lengths.
Which lens for which photo
- Portraits: step back and use 2x to 3x. The same face at 0.5x from close up looks stretched, with a bigger nose and smaller ears.
- Landscapes: ultra-wide for big skies and foreground interest, telephoto to pick out layers of hills or a single tree.
- Rooms and buildings: ultra-wide, with the phone held level, so verticals don't lean.
- Food and products: main or 2x, a little further back, for natural proportions.
- Low light: the main camera almost every time.
- Close-ups: on many phones, "macro" mode is the ultra-wide lens focusing very close.
Optical zoom, digital zoom and lens switching
At the zoom levels printed on the buttons (0.5x, 1x, 3x and so on), you're using a real lens. In between, the phone crops and enlarges the image from the lens below. That's digital zoom, and quality drops the further you go from the last real lens.
Phones also switch lenses on their own. In dim light, "3x" may quietly use a crop of the main camera, because its bigger sensor gives a cleaner result than the small telephoto. That's usually a sensible choice, but it can surprise you.
If you're unsure which lens is in use, cover each lens with a finger in turn and watch the viewfinder.
Choosing the lens yourself
One Camera gives you every lens your phone exposes (wide, ultra-wide and telephoto), with a zoom ladder for exact focal lengths as well as pinch zoom. That makes it clear which real lens you're shooting on. Which lenses an app can use depends on what the manufacturer makes available, and you can check that for your phone.
Questions
What is the difference between wide, ultra-wide and telephoto on a phone?
The main (wide, 1x) camera is the all-rounder with the best low-light quality. The ultra-wide (0.5x) fits more in the frame but distorts near the edges. The telephoto (2x and above) brings distant subjects closer and flattens perspective, which suits portraits.
Is telephoto or ultra-wide better?
Neither is better overall. Use ultra-wide for landscapes, rooms and groups, and telephoto for portraits, details and distant subjects. In low light, the main camera usually beats both.
Why does my phone's 3x zoom look blurry at night?
In dim light many phones switch from the small telephoto to a digital crop of the main camera, and handheld shake at longer focal lengths adds blur. Brace the phone, or step closer and use 1x.
