HOW FAR CAN TV cameras zoom?
So a 12 X 20 zoom lens has a minimum focal length of 12mm and a maximum focal length of 240mm. The zoom lenses on most handheld field cameras have ratios in the range of 10:1 to 30:1. The photos below show the effect of zooming from a wide-angle position to a telephoto view with a 30:1 zoom lens.

What are the 3 types of lenses?
- Concave lens: The centre of the concave lens is thinner than the edges.
- Convex lens: The centre of the convex lens is thicker than the edges.
- Plano lens: One side of the Plano lens is flat and the other side is either concave or convex.
What lens do Hollywood movies use?
Standard Focal Length Lenses: 40mm and 50mm
On a traditional Super 35 cinema camera, a 40mm is probably closer to our natural field of view – and while some even say it’s the 35mm. Both the 40mm and the 50mm lenses have been widely used on Super 35 throughout cinema.

Cine lenses have superior glass that produce sharp images with little to no chromatic aberrations or visible vignetting, which are sometimes present in images taken using photo lenses. However, both types of lenses can’t avoid barrel distortions, especially in video where it is more noticeable.

- Color Refractive Correction.
- Distortion.
- Perspective / Focus Shift.

Focal lengths such as 300mm or 400mm would be a large, heavy telephoto lens for taking photos of birds or airplanes. Just remember – a small number is wide, a large number is telephoto. Two numbers together, e.g. 35-105mm, means that the lens zooms from one focal length to another.

What is the main problem with a powerful telephoto lens?
The accompanying (kit) telephoto lens is a lot bulkier and generally not very fast (aperture), so it’s harder to get sharp pictures. Physical size aside, telephoto lenses along with the use of slower shutter speeds can lead to camera shake due to the magnification ratio.
How does TV camera work?
The television camera is a device that employs light-sensitive image sensors to convert an optical image into a sequence of electrical signals—in other words, to generate the primary components of the picture signal.In this way the entire scene was scanned, one line at a time, and converted into an electric signal.
How does a TV make pictures?
A standard TV set turns the video signal into beams of tiny particles called electrons. It shoots these beams at the back of the screen through a picture tube. The beams “paint” the pixels on the screen in a series of rows to form the picture.
What is the difference between a zoom lens and a telephoto lens?
The basic difference between a Telephoto and Zoom lens is that a Zoom lens has a variable focal length and is used for dynamic photography while a telephoto lens has a fixed focal length of greater than 50mm and is used for static photography.
Why are TV lenses so expensive?
Because of the length of the signal path between the camera sensor and the transmitter is huge compared to a handheld camcorder. The cameras are further away from the talent which requires more expensive lenses. Producing a class A video signal requires a lot more electronics and processors inside the camera body.
Why are TV studio cameras so large?
As Zebra Zone explains: in traditional video, it’s the environment that adapts to the cameras, in broadcast its the opposite, it’s the camera that has to adapt to the environment. And any setup that can adapt to almost any environment is going to have to be massive and expensive.
