What is a typical price for a set of Bushnell binoculars?
Bushnell manufactures various models and sizes of binoculars, all for different prices. For example, the Legend Ultra HD 10 by 36 mm. binoculars are roughly $370 USD. The 8 by 42 mm. binoculars of the same model are roughly $390 USD.
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
Telescope lenses are able to gather more light than the lens of the human eye primarily because telescope lenses are?
Larger in diameter. The human eye can open to a maximum of about 7mm. Calculate the area of that, and compare it with a 50 diamter mm lens. (A=pi*r^2). Where 3.5 = radius of the pupil and: 25 = radius of the lens pi * 3.5^2 mm = 21.99 mm ^2 (area of a pupil in the dark) pi* 25^2mm = 1963.5 mm^2 Therefore, a 50 mm lens would have 89.29 more light grasp than the eye.
How much better resolution would a 60 mm objective lens have than your eye's 6 mm exit pupil?
54
How many cm is in 30 mm?
Well, There are 10 mm in 1 cm, so 10 times 30 is 300 300 mm are in 30 cm
A 84 mm focal-length lens is used to focus an image on the film of a camera The maximum distance allowed between the lens and the film plane is 120 mm How far ahead of the film should the lens be if?

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.
Which camera lens is good 50 mm or 80 mm?
Both are good for different purposes.
How does mm convert to lens magnification?
With 35 mm film cameras, the 35 mm refers to the film size, not to be confused with the lens size. A 50 mm lens is usually considered the normal or neutral size, with a magnification factor of one. A 50 mm lens has no magnification. So, as the size (millimeters) of the lens become larger, the magnification of the image becomes greater. A 100 mm lens gives 2 times magnification, and makes the subject appear 2 times closer and gives less viewing area; a 200 mm lens gives 4 times magnification, and so on. A 25 mm lens would make the subject look farther away by a factor of 2 and give a wider viewing area. Fisheye lenses, usually about 8 to 15 mm, give a very wide view and negative magnification. The increased area appears as a distorted "fisheye" view. Digital cameras have electronic image sensors which are usually smaller than the area of film exposed in a 35 mm camera, and lenses will have a different magnifing effect. It is not a problem, though, as the manufacturer almost always gives a calculation of the equivalence of the lens with the digital camera compared to a 35 mm film camera, and calculates the magnification of the lens of the digital camera.
30 mm is how many feet?
30 mm = 0.098425 '
Which lens is greater than 50 mm?
a greater 1
Which is largest cm or 30 mm?
1 cm = 10 mmThen 30 mm is larger than 1 cm.
To convert 30 millimeters to inches?
As 25.4 mm equal 1 in exactly, divide 30 mm by 25.4 mm/in to convert it to inches. → 30 mm = 30 ÷ 25.4 in ≈ 1.18 in
