Comparison with Camera Lens Focal Length For example, a 10x binoculars magnification is equivalent to a 500mm super-telephoto lens.
What focal length is 10X magnification?
So, a 10x magnification binocular equals a 500mm lens, according to Nikon.
What magnification is a 400mm lens?
To calculate the magnification value of a lens, the focal length value of the lens needs to be divided by 50mm, the 1X equivalent magnification. So, for example, a 400mm lens on a full frame sensor camera has a binocular-equivalent magnification of 8X (400mm divided by 50mm).
How do you convert focal length to zoom ratio?
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 many times zoom is 300mm?
Here is an example: For a 300mm lens, divide 300 by 50 to get 6x magnification.
How far will a 300mm lens zoom?
The bottom line on a crop frame camera a 70-300mm zoom (Canon, Nikon, Sony) will get you pretty good coverage from 15 yards to 56 yards away, the ‘sweet spot’ for outdoor sports. If you’re shooting a full frame camera the Canon 100-400mm gives similar coverage.
What is 10x optical zoom equivalent to?
Understanding Zoom Lens Numbers
For example, a 10x zoom lens may have a 35mm film equivalent range of 24mm-240mm. But a 10x zoom lens on a different camera may have a 35mm-350mm equivalent.
What does 30X optical zoom mean?
The 30x magnification range is nothing short of incredible, allowing you to zoom up to distant subjects while still maintaining the clarity that only optical zoom can provide.And by combining this function with Digital Zoom, up to 120x zoom* can be achieved without sacrificing image quality!
What is 50x optical zoom?
The 50x optical zoom lens is a 35mm equivalent of 24-1200mm, which can be extended to 100x using Zoom Plus.When zooming you can use Enhanced Zoom Framing Assist to help keep track of subjects in the distance. Videos are recorded at full 1080p HD at 24 fps with stereo sound.
What is 20X optical zoom equivalent to?
At an aspect ratio of 4:3, the Canon 35 millimeter 20x optical zoom lens range is an impressive 51.8 to 1036 millimeters (35 millimeter equivalent). At the 16:9 aspect ratio, its zoom range is an equally impressive 42.2 to 844 millimeters (35 millimeter equivalent).
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 is 10X zoom in mm?
Now, at MWC 2019, it has revealed that the phone will be officially out in the spring. Having a 10x zoom on a camera phone is no mean feat: it means the device will offer a zoom ranging from 15.9mm to 159mm (the equivalent of).
How far can 75 300mm lens shoot?
Canon EF 75-300mm f/4-5.6 III Specs
| Focal Length | 75 to 300mm |
|---|---|
| Minimum Focus Distance | 4.92′ / 1.5 m |
| Maximum Magnification | 0.25x |
| Optical Design | 13 Elements in 9 Groups |

HOW IS zoom lens magnification calculated?
On a full-frame digital or 35mm film camera, 1x magnification is achieved by using a 50mm lens. Therefore, a 100mm lens is 2x, 200mm lens is 4x, etc. To get the optics magnification factor, simply divide the focal length of the lens by 50.
How far does a 18 55mm lens zoom?
If you use the minimum focal length of 18mm, it can reach subjects that are as far as 5 feet away. If you use the maximum focal length of 55mm, it can reach subjects that are as far as 18 feet away from you.
What is the focal length of a 300mm lens?
Matching Lenses to Photographic Needs
| Lens Type | Focal Length | Best Use |
|---|---|---|
| Wide Angle | 28mm or lower | Landscapes and Interiors |
| Standard | Anything from 35mm to 85mm | Portraits |
| Telephoto | Anything from 100mm to 300mm | Portraits and Sports |
| Super-Telephoto | 300mm or higher | Wildlife and Sports |
What is a 300mm lens good for?
So what are telephoto and superzoom lenses, like a 70-300mm, used for? They’re best when you want to get close to a distant subject. It could be a building on the horizon or a face in a crowd. They’re perfect for wildlife photography, where you can’t get close to the animals you want to shoot.
Is a 300mm lens good for wildlife?
The best lenses to capture wildlife action also cover a lot of range.It’s hard to get close to most wild subjects, so wildlife photographers generally use long lenses: at least 300mm for an APS-C DSLR, or 400mm for a full-frame DSLR or 35mm SLR. If you can get fairly close to larger animals, a 70-200mm zoom can work.
Is 10x optical zoom enough?
At least 10x zoom is needed, but 50x optical zoom or even more is better. Many professional wildlife photographers go for very long lenses that enable them to photograph wildlife from a significant distance. If you can’t afford a lens with a long focal length, then a high zoom range is what you should go for.
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.
How far can 30x zoom See?
0-250 feet
Surveillance With An Optical Zoom Lens: Comparing 30x, 36x, 44x, And 55x. A basic surveillance camera can see anywhere from 0-250 feet at night, depending on the IR, camera model and lens.
