What is 200mm zoom equivalent?
So, a 200mm lens on a 35mm frame is about a 4x “zoom” to your eyes. On the 20D with the 1.6 crop factor, 200mm is about a 6.4x “zoom” ((200 x 1.6) / 50).
What is 50x zoom equivalent to in mm?
The 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body.
How much magnification is a 200mm lens?
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.
What magnification is 200mm?
200mm Magnification Ratio When it comes to 200mm lenses, the distance of how far you can take pictures refers to the magnification ratio. While the magnification ratio varies depending on the brand, a 200mm lens typically has a 2.85x magnification rate. Thus, a 200mm would make subjects appear 4 to 5 times closer.
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 many mm is 25x zoom?
There’s just one more thing to know. The typical consumer DSLR uses a sensor smaller than full-frame, and has an associated crop factor . 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 is 4x digital zoom?
Nikon Coolpix 990 has a 4x digital zoom in fix steps from 1.2x to 4.0x with an increment of 0.2x. Thus, this digital zoom capability effectively creates an optical/digital zoom of focal length from 138mm for 1.2x to 460mm fro 4.0x.
How do you calculate the zoom of a lens?
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 do you calculate the magnification of a zoom lens?
Just move the decimal point two places to the left and multiply by 2. Here is an example: For a 300mm lens, divide 300 by 50 to get 6x magnification. Or divide 300 by 100 to get 3, then multiply 3 x 2 to get 6x. Another example: For a 100mm lens, divide 100mm by 100 to get 1.
Can a 50-500mm lens be a 10x zoom?
But, a 50-500mm lens would also be a 10x zoom, so would a 28 to 280mm lens. It just means the long focal length is 10 times the short focal length. Obviously these three lenses would not yield the same field of view or magnification assuming they were mounted on identical cameras, except in their overlapping ranges.
What is the zoom range of the Zuiko 50-200mm?
The Zuiko Digital ED 50-200mm f2.8-3.5 SWD lens is a high-performance super-telescopic zoom lens that features, for the first time, the SWD (Supersonic Wave Drive) autofocus system and covers a zoom range equivalent to 100 to 200mm of a 35mm camera lens.
Why are 70-200mm equivalents to 50-150mm?
The reason is that in order to account for the crop factor, you also have to multiple the aperture by the crop factor. A 50-150mm F2.8 lens on a cropped sensor is effectively a 70-200mm F4 lens on a full frame and that’s why they have similar weights and prices.
How big of a zoom is a 200mm lens?
So, a 200mm lens on a 35mm frame is about a 4x “zoom” to your eyes. On the 20D with the 1.6 crop factor, 200mm is about a 6.4x “zoom” ( (200 x 1.6) / 50). Re: 200mm how much zoom? Do not confuse the term “zoom” with the term “magnification”.
