The SX740 is a compact camera with a big zoom lens within. Its 40x optical lens means it can capture from an equivalent 24mm wide-angle (wide enough for shots of groups, say, or landscapes), through to a massive 960mm equivalent (long enough to pick out far-away subjects and make them appear close-up within the frame).

## What is range of optical zoom?

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?

Maximum Usable Distance 20X:

Distance from Camera Lens (ft) 10′ 20′
20X Tele Angle 0.7 1.4
20X Wide Angle 12 24

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

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?
