What is 24x zoom in mm?
This has a 24x zoom lens. It is described as having a zoom range of 25 to 600 mm. However, these are the “35mm equivalent” values which are useful for comparison purposes…. Latest buying guides.
What is 24x zoom?
“24x zoom” means that the longest focal length of the lens is 24 times the shortest focal length.
How many mm is 25x zoom?
Typically this is about 1.5 or 1.6, so the 25mm wide setting becomes 25/1.5 = 16.7 mm and 300mm becomes 300/1.5 = 200 mm.
What is a 30X optical zoom in mm?
Sony DSC-HX200V 30X optical zoom is equivalent to 810mm zoom.
What is 15x optical zoom in mm?
24-360 mm
It’s a 15x optical zoom – the equivalent, in 35mm terms, to 24-360 mm – and is a 24mm ultra-wide angle chunk of LEICA DC VARIO-ELMAR glass.
What is 15x optical zoom?
However, it uses that single lens to its advantage. It’s a 15x optical zoom – the equivalent, in 35mm terms, to 24-360 mm – and is a 24mm ultra-wide angle chunk of LEICA DC VARIO-ELMAR glass.
What is optical zoom number?
The optical zoom refers to the range between the two, regardless of its wide-angle or telephoto capabilities. While a 50x optical zoom lens sounds like an impressive measurement, it is not necessarily better equipped to shoot at telephoto range as that of a 42x optical zoom lens.
What is 5x optical zoom equivalent to?
In smartphones, manufacturers have started using periscope lenses for better optical zoom. They’ve been able to put 5x zoom lenses (roughly equivalent to the magnification of a 100mm lens on a DSLR, so pretty good) in their flagship phones without making them any thicker.
What’s the difference between digital and optical zoom?
A digital zoom is not the same as an optical one. Another thing to look out for along is the focal length of the lens. The focal length (read as ‘XX’mm) is the strength with which the lens can focus on an object, while the optical zoom (the number ‘X’x zoom) is the strength of the total zoom you can achieve.
What’s the difference between 3x and 11x zoom?
For example a 18-55mm lens would have a 3x optical zoom, and a 18-200mm lens would have a 11x optical zoom. Is that right? The “times zoom” notation is simply the big number divided by the small one, so the examples you give are correct. “3x zoom” simply means the longest focal length is three times the shortest.
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.
How does a zoom lens work on a camera?
There are two types of zoom – optical and digital Optical zoom works by physically moving the camera’s lenses and changing the focal length. Optical zoom lenses physically extend to magnify the subject. A motor controls the lens movement according to the user’s command.
