What is 4x optical zoom equivalent to?
Many times when you are reading about a compact camera, they will give both types of measurements. For example at 2x zoom has a focal length equivalent of 35mm to 70mm and a 4x zoom has a focal length equivalent of 35mm to 140mm.
What is 40x optical zoom equivalent to?
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 meant by 3X optical zoom?
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.
What does 42x optical zoom mean?
If a 42x optical zoom lens has a wide-angle setting of 25mm, then its maximum telephoto setting would be 1050mm (25 multiplied by 42). It’s important to pay attention to the optical zoom measurement as well as the maximum telephoto setting.
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 does 5x zoom mean?
5x optical magnification covers the most commonly used focal lengths, from wide-angle for taking in the whole scene to medium telephoto for flattering portraits.
What focal length is 60x zoom?
3.58-215mm
The New Lumix DMC-FZ70 Digital Camera: 60x Optical Zoom
Image Sensor | 1/2.3″ Backside Illuminated MOS |
---|---|
Optical Zoom | 60x |
Focal Length | 3.58-215mm |
Focal Length (35mm equiv.) | 20-1200 mm (22–1320mm in video recording) |
Maximum Aperture | f/2.8-5.9 |
How many mm is 50x zoom?
24-1200mm
The 50x optical zoom lens is a 35mm equivalent of 24-1200mm, which can be extended to 100x using Zoom Plus.
What does 10x zoom mean?
10x is the optical zoom, roughly equivalent to a 20-200mm lens on an SLR camera. It’s pretty good. The 4x Zoom means that beyond the 10x optical zoom, the camera will electronically jack it up another 4 times.
What does 1x zoom mean?
A digital camera at its widest angle is said to have a 1x zoom. However, since the widest angle will vary with almost every camera, an absolute millimeter value for a 3x zoom is impossible. If the widest angle is equivalent to 35mm, 3 times that would be 105mm. If the widest angle was 25mm, it would be 75mm.
Which is better optical zoom or digital zoom?
This is digital zoom: The camera’s processor crops into the center of the photo. Optical zoom is ultimately better, as it magnifies an image to fill the entire image sensor — say, 10 megapixels worth. Digital zoom takes just the center portion of what the lens threw on the sensor, capturing fewer pixels, say 6MP.
What does 35mm focal length with 10x optical zoom mean?
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 much optical zoom do I need for photography?
You will need a great deal of optical zoom, at least 10x. If you’re taking single subject pictures without much interest in the surroundings, then a narrow perspective camera with 10x or 15x optical zoom is excellent in getting the right kind of detail, like the lion’s eyes or the eagle’s beak.
Is it worth buying a digital zoom lens for my camera?
But yes, only after a certain point. Till then, you just need a better camera. As far as optical zoom is considered, it is generally a good practice to stick to optical and not digital. 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.
What is the difference between optical and digital 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.
