What is the difference between optical zoom and regular zoom?

In short, optical zoom allows to you bring the object close before you capture it. With digital zoom, your camera uses a part of the image and sizes it later. That's why the risk of losing image quality is greater with digital zoom. You can compare it to seeing pixels when you magnify a small image.

Do iphones have optical zoom?

Optical zoom provides a crisp, clear image using the camera hardware, but digital zoom uses software enhancement to crop in. 5x optical zoom is an ‌iPhone 15 Pro‌ Max-specific feature that is not available on the ‌iPhone 15 Pro‌, which is limited to 3x optical zoom.

How far is 4x optical zoom?

However, a rough rule of thumb is that with a 4x zoom ratio you can ID someone 100 feet away.

Does Samsung S23 have optical zoom?

As a quick refresher, the S23 Ultra has two telephoto cameras — one with 3x optical zoom and another with 10x optical zoom. And using the main 200MP camera, you can digitally zoom all the way up to 100x.

Is 25x optical zoom good?

Zoom factor

In terms of simple zooming capability, it may mean that digital zooms bring a picture closer or zoom closer but since they lose picture quality so they do not capture the picture well. So a 25x optical zoom may turn out better results than a 700x digital zoom also.

How far can 25x optical zoom see?

The 25X optical zoom lens on the camera also comes in handy when trying to see faces; it can see a face up to 300ft away when zoomed in during the day, or 260ft during the night. The HD 1080p video produced by the camera is beautiful and clear, something to be expected from a professional high definition PTZ camera.

What focal length is the human eye?

Although the human eye has a focal length of approximately 22 mm, this is misleading because (i) the back of our eyes are curved, (ii) the periphery of our visual field contains progressively less detail than the center, and (iii) the scene we perceive is the combined result of both eyes.

Which phones have 5x optical zoom?

Optical zoom still wins

Take a look at the iPhone 15 Pro Max's new 5x telephoto lens compared to the Samsung Galaxy S23 Ultra at 5x, which is between its 3x and 10x optical zoom focal lengths. A 5x zoom photo from the iPhone 15 Pro Max (left) versus 5x digital zoom on the Samsung Galaxy S23 Ultra (right).

What is the difference between 5x and 10x optical zoom?

5x means that the ratio from wide to long focal length is 5 to 1 for example 28mm to 140mm, 32mm to 160mm etc. 10x would mean 28mm to 280mm, 32mm to 320mm etc. Simply multiply the lower number by the zoom ratio.

How far can 3X optical zoom see?

A “3X zoom” doesn't mean the subject is actually magnified 3X. It just means the lens can zoom to three times that widest focal length number. So, a 3x zoom that starts at 28mm would zoom in to 84mm, but a 3X zoom that starts at 24mm would only zoom in to 72mm.
