What is 12X optical zoom?
Ideal for high magnification applications requiring the optimal balance between optical performance, large zoom range and price, the 12X offers incredible 12X (0.58-7X) magnification, increased resolution with 0.004-0.550 N.A., and unmatched edge flatness and clarity.
How far can you see with 50x zoom?
The 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body. The 4x digital zoom brings that up to 4,800mm equivalent, but you’re still probably better off sticking with the optical and scaling in post if you need to. That being said, it’s still pretty impressive.
How far can 40x optical zoom See?
960mm
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 a good zoom lens size?
The longer the focal length, the closer you can zoom in on a distant subject. Many entry-level DSLRs come with an 18-55mm lens in the package, which is a good choice as a general-use lens. For more zoom power, you’ll need a telephoto lens, which typically falls within the 55-300mm range.
What range is 12X zoom?
0.58X to 7X
With a zoom ratio of 12:1, a zoom range of 0.58X to 7X and a dynamic magnification range of . 07 to 583X, the 12X is the only single lens system to provide such a high combination of zoom range and resolution.
What does 50x magnification mean?
The magnification power of a telescope essentially indicates the size of an object observed inside the eyepiece relative to the size of that object when observed with the naked eye. For example, when observing Mars at 50x magnification, the red planet will appear 50 times larger than if you looked at it with your eyes.

How do I choose a zoom lens?
Zoom lenses always have two focal lengths specified, for example 18-55 mm, indicating the zoom range of the lens. If you want this translated into compact camera language, you can just divide the largest number by the smallest, which in the 18–55 mm case gives a zoom of about 3x.
