What is 4x30 Binocular?
Binoculars are specified by numbers such as 4×30, the first number gives the magnification of the object and the second number gives the aperture in millimeters. Good binoculars with a large aperture (50 mm or more) are useful at night for astronomy.Read more: binocular
Is 3.4 cm bigger then 30 mm?
No, 3.4 cm is not bigger than 30 mm. In fact, 3.4 cm is equal to 34 mm, which is larger than 30 mm. Therefore, 3.4 cm is bigger than 30 mm.
Telescope magnification power with a 30 mm eyepiece for a telescope?
To calculate the magnification power with a 30 mm eyepiece, you need to divide the focal length of the telescope by the focal length of the eyepiece. For example, if the telescope has a focal length of 600 mm and you use a 30 mm eyepiece, the magnification would be 20x (600 mm / 30 mm = 20x).

What does the "mm" in a camera lens mean?
The "mm" in a camera lens refers to the focal length of the lens, which determines the angle of view and magnification of the image.
What is the difference between 3.6 mm lens and a 6 mm lens camera?
2.4 mm All kidding aside: the 3.5mm lens has a wider angle than the 6mm one. This means that in a picture, you will see a larger area with the 3.5mm lens, but with the 6mm lens you'd see more (sharper) detail.
12x lens equals how many mm?
In standard film camera reference which is commonly used, a 50 mm lens equals a neutral value, or 1x magnification, so a 12x lens would be 600 mm.
What is the difference between a 200mm lens and a 20 times lens?
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.
What does "mm" mean on a camera lens?
"mm" on a camera lens refers to the focal length of the lens, measured in millimeters. It indicates how much the lens can zoom in or out, with larger numbers representing a longer zoom or telephoto lens, and smaller numbers indicating a wider angle or wide-angle lens.
Which camera lens is good 50 mm or 80 mm?
Both are good for different purposes.
What does a higher mm lens mean in terms of camera photography?
A higher mm lens in camera photography means that the lens has a longer focal length, which allows you to zoom in closer to distant subjects and capture more detail.
What does the term "300 mm lens" refer to in photography?
The term "300 mm lens" in photography refers to a lens with a focal length of 300 millimeters. This type of lens is typically used for capturing distant subjects or for close-up shots with a narrow field of view.
30 mm is how many feet?
