What is 18x optical zoom equal to?
28- to 504 -mm
Its 18x optical zoom is equivalent to a 28- to 504 -mm lens for a film camera. Its range is wide enough for shooting in both tight quarters and at great distances.
How do you calculate optical zoom?
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.
What does 50x optical zoom mean?
The 50x optical zoom lens is a 35mm equivalent of 24-1200mm, which can be extended to 100x using Zoom Plus. Thanks to its Ultra Sonic Motor the lens has near-silent zooming. To help take the sharpest shots possible there is 4.5 stop optical image stabilisation.
What’s the equivalent of a 10x optical zoom?

How to compare optical zoom of point and shoot?
It will show you something is “mm”, generally starting from around 5 mm. Since it has 10X zoom the reading would be 5mm to 50mm (5X10 = 50). Now, since the camera has 6x crop factor, we will multiply both end of focal lengths by 6 to get a “35 mm equivalent” focal length. In this case it would be 5X6 =30mm and 50X6 = 300mm.
How big is the Zoom on a DSLR?
It will show you something is “mm”, generally starting from around 5 mm. Since it has 10X zoom the reading would be 5mm to 50mm (5X10 = 50). Now, since the camera has 6x crop factor, we will multiply both end of focal lengths by 6 to get a “35 mm equivalent” focal length.
What’s the difference between focal length and optical zoom?
optical zoom = maximum focal length / minimum focal length For example a 18-55mm lens would have a 3x optical zoom, and a 18-200mm lens would have a 11x optical zoom.
