If your phone has multiple rear cameras, it's not just for show: each lens is designed for a different type of photo, from everyday shots to creative ones. In everyday use, the most important lens is almost always the main one, because it's the one you use most and the one that usually performs best in low light.

Before we go into each lens individually, here's a key idea to keep you on track: in mobile phones, quality doesn't just depend on "more megapixels," but also heavily on the sensor (size, light-gathering capacity) and the lens + processing combination.

Main Lens: The One You Always Use

The main lens (also called the "main camera") is the one your phone uses by default when you open the camera app, and it almost always has the most capable sensor. That's why, in the late afternoon, indoors, or when there are unusual shadows, this lens usually takes better photos than the others, because a larger sensor can capture more light and reduce noise.

In practice, the main lens is a versatile tool because it works for photos of people, food, pets, documents, "normal" landscapes, and also for most videos. This versatility comes from the fact that it usually has better stabilization and focus than the rest (especially in mid-range phones).

If you're buying a phone and want to get it right quickly, prioritize this lens because it's the one that will define how your memories look 80% of the time. The others (telephoto, wide-angle, macro) add a lot, but are usually a "second step".

Telephoto: real zoom (and better portraits)

The telephoto lens is the one for getting closer without the photo becoming a pixelated square: its beauty is the optical zoom, which enlarges the image without "cropping" it like digital zoom does. That's why it's ideal for concerts, photos of your child playing in the distance, details of buildings, or any scene where you can't (or don't want to) get closer.

In addition,The telephoto lens usually favors more natural portraits because it has a narrower field of view,It helps to better separate the subject from the background and achieve a more "pro" look with a blurred background (bokeh). On many phones, it also uses software to extend the range with hybrid zoom, although the quality may drop compared to pure optical zoom.

If your phone has a telephoto lens, use it for outdoor portraits in good light; you'll notice faces are less "distorted" than with very wide lenses. And if you don't have a telephoto lens, try not to overuse digital zoom: it's better to crop later, or get closer yourself.

Wide-angle and macro: for "wow" moments and for details

There's a common misconception here because on many phones, the main lens is already a "standard" wide-angle lens, and what people call "wide-angle" is usually actually the ultra-wide-angle lens (even wider). The idea is simple: this lens captures much more of the scene in a single shot, which is perfect for landscapes, monuments when you're very close up, narrow interiors, and group photos.

The downside of a wide-angle lens is that it can distort the edges a bit (stretched faces, curved lines), so it's not always the best for portraits. Use it when the important thing is to "fit everything into the photo," not when you want the most flattering look.

Now, the macro lens is used to focus very closely and take close-ups with a lot of detail (flowers, textures, insects, products, etc.). On many phones, macro mode is activated from the camera app (sometimes with a flower icon) and allows you to shoot at short distances; several models work at around a few centimeters to achieve that close focus.

So, which is the most important? For most people, the "real" order is usually:

Today, almost every phone comes with a "combo" of cameras, and although at first it may seem like pure marketing, the idea is quite simple: each lens is designed for a specific type of scene.

With this clear, when you open your camera you'll know what you're choosing and which lens is best for each situation. Ultimately, it's not about having a thousand lenses, but about understanding when to use each one so your photos turn out exactly as you envisioned.And what people call a "wide-angle" lens is usually actually an ultra-wide-angle lens (even wider).
