What Is an Telephoto Lens iPhone?

With an telephoto lens iPhone, you can take clear photos on zoom. It is a camera lens which doesn’t compromise on the quality of your image!

This lens enables you to capture the far subjects as if they are close to you. Sounds Amazing!

So your telephoto photos will look sharper, more natural, and more detailed.

Example: If you take a picture of a building with a normal lens, it will appear small. But with a telephoto lens, the same building will appear zoomed in, clear, and without any blur. Isn’t that wonderful!

 

How Does a Telephoto Lens Work?

The iPhone Pro models usually have 3 lenses:

1. Wide lens (Main Camera) – its for normal photos

2. Ultra-Wide lens – its to cover a wider area

3. Telephoto lens – For zoom and portraits.

Where It’s Used Most?

Portrait photography (for background blur effect)

Wildlife shots (for capturing distant subjects without getting too close)

Event photography (for close-up shots without disturbing the moment).
