This is a lens that magnifies the image 20 times.
The maginification of the yellow lens in my biology class is 20X
200X 20X * 10X The 10X is the ocular lens of compound microscopes. Where your eyes go.

A zoom lens with a big range, from slightly wide-angle to long telephoto. The 20 measures the range, some lenses are not so strong, say 10x.
A microscope is a tube that holds glass lens mounted that have the right focal properties that magnify the image.
The Canon Vixia HF R100 HD digital video camera has the best resolution and it costs less than $500.00. This camcorder provides 1920x1080 resolution, making your videos as clear as they can be. The combined power of the image processor, 20x HD Video Lens with the 2.39 Megapixel HD CMOS Image Sensor are what produces such great resolution at this price.
It depends on the actual focal length. For a 35 mm format lens, 200 mm is about 4x magnification, to get 20x you'd need a 1000 mm lens. For smaller formats, such as 8 mm or a camcorder, find the focal length for normal view, then multiply by 20.
