Why Budget Phone Cameras Use Multiple Lenses

Phone makers know shoppers compare the back of the phone. Three circles look more advanced than one. Extra lenses are also a fairly cheap way to add a feature to a budget smartphone camera. A low-resolution macro or depth sensor costs far less than a big main sensor with optical image stabilization (a tiny motor that steadies the lens so shots are less blurry). Marketing then lists “quad camera” in big letters.

The catch: those extra cameras often do one narrow job. A 2MP macro lens (2MP means about two million dots of image detail) can be fun in bright light. In a dim kitchen, it’s close to useless. A depth sensor doesn’t take normal photos at all; it helps the phone guess what’s in front and what’s behind. Some budget phones even include a “macro” camera that’s mostly there to fill a circle on the back.

What this means for you

Don’t buy by lens count. Buy by the main camera. Look for a phone with a good main sensor, optical image stabilization if your budget allows, and reviews that show real photos in indoor light. Check what the second and third lenses actually are. An ultrawide lens is useful for group shots and travel. A 2MP macro or depth sensor is a bonus, not a reason to pay more.

If you’re choosing between two phones, ignore the one with four cameras if its main camera is weak. A budget phone with one strong main lens and a decent ultrawide will beat a four-lens phone with a soft main camera. Use the savings on storage or a case. (Your photos will thank you.)

Key Takeaways

• Multiple lenses let a budget phone cover wide, close-up, and portrait shots.
• Extra lenses are often cheaper and lower quality than the
