You have already wondered why modern cell phones have three, four or even more cameras In the rear?
I also thought it was exaggeration… until I found out that Each lens has a specific function - And together, they make amazing photos that a camera alone could never.
Let's unravel this mystery!
1. The evolution: from a single camera to a complete system
In the beginning, the cell phones had Just a rear camera, and the photos were… very medium. A single lens did not realize everything.
- Problem: A camera just can't capture large anguish, unfocused portraits or quality zoom.
- Solution: To add Specialized Lenses for each situation.
From there was born the Multiple camera system - And today, this has become standard even on intermediate cell phones.
2. What is each camera for?

Most mobile phones with three cameras have this configuration:
🔹 Main Camera (Wide)
- Function: Standard photography, with good quality in any situation.
- Detail: It has the best sensor and captures colors and light more accurately.
🔹 Ultra-wide (large-angle)
- Function: Photos with Greater Field of Vision (Ideal for landscapes or groups).
- Example: If you want to photograph an entire building without having to walk away, this lens resolves.
🔹 Telephoto (optical zoom)
- Function: Approximation without losing quality (Unlike digital zoom, which only cuts the image).
- Advantage: Currently photos with sharpness, perfect for details or events.
Some cell phones still have a fourth camera (macro, depth or even infrared), but these three are the essentials.
3. Why not use only one camera with AI?
"But if artificial intelligence is so advanced, why not improve a single camera instead of using several?"
Good question!
- Hardware> Software - No algorithm can simulate an optical zoom or a real angle without loss of quality.
- Professional photos need real lenses - It was helping, but it does not replace the physics of multiple lenses.
I.e: The more specialized cameras, the more versatile and professional your phone gets.
4. Is it worth having a cell phone with 3 cameras?
It depends on its use:
✅ It's worth it if…
- You like photography and want more options (such as zoom without losing quality).
- Want a cell phone that is not outdated so fast.
❌ Maybe you don't have to ...
- Just take casual photos and doesn't care about zoom or professional effects.
- Prefer to save and get a simpler model.
But one thing is certain: The tendency is for even basic cell phones to gain multiple cameras In the coming years.
Conclusion: Multiple cameras = more creative freedom
It's not just marketing - having three cameras (or more) It really makes a difference in the quality of your photos. Each lens has a purpose.
So, what's your current phone?
