What does 25x optical zoom mean?

A 25x zoom simply means the longest focal length is 25 times the shortest focal length. So a 24-600 means that 600/24=25 times. The 18-400 is a 22x focal length, but the effective focal length is 27-600mm on the Nikon camera.

How far can 30x optical zoom See?

HOW IS zoom lens distance calculated?

To determine the overall zoom ratio of the lens, simply divide the longest focal length by the shortest. So, for example, the Sigma 18-35mm F1. 8 DC HSM and the 8-16mm F3. 5-4.5 are both examples of 2x zoom lenses: 35 divided by 16 equals 1.95, and 16 divided by 8 equals 2.

How far can 20x optical zoom See?

How is zoom distance measured?

What’s the minimum zoom for a 35 mm camera?

This means that if the camera you’re buying says 35 mm focal length with a 10x optical zoom, this means the minimum distance of the lens is 35 mm and the maximum zoomed-in distance would be 350 mm.

How big of a lens do you need for a 10x zoom?

Now, a lens of 28 mm focal length and 10x zoom would mean the minimum distance is 28 mm and the maximum is only 280 mm, but the lens would give a much wider perspective than a 35 mm lens. This is why it is very important to know what kind of pictures you’re going to take and then buy the appropriate camera, rather than getting the biggest one.

Is there an optical zoom calculator for PTZ cameras?

This PTZ camera optical zoom calculator can be used to determine the video image created by a PTZ camera when zoomed in at various lengths. The calculator uses PTZOptics 12X, 20X and 30X lenses to create the height and width of your image in real life.

What kind of Zoom does the Galaxy S21 Ultra have?

There are four lenses on the back: a standard zoom, an ultrawide lens, a 3x optical zoom and a 10x optical zoom. Together with the huge 108-megapixel resolution of the main camera, the phone can achieve a whopping 100x zoom overall. (Here are all the new Galaxy S21 Ultra camera features and how to use them.)
