Most people who use a camcorder do not understand exactly what the focal
length
is. This is because you don’t really need to understand this
term to use your camera. If you want to make the most out of your video
camera, however, then you should learn about these unknown terms. These
terms relate to important things about the lens of your digital video
camera. While this might not be essential to learn about, it should make
it much simpler to take great photos.

By learning more about your lens and camcorder, it should be much
simpler to take great quality home movies by making the most out of your
digital camcorder. Finding out about the focal length will make it much
simpler to choose a camcorder that you will be happy with.

What Is the Focal Length?

The focal length is the distance between the camcorders lens to the
focused image when the lens is focused on infinity. You might be aware
of the focal length even if you haven’t heard about it before. It’s
useful to change what you are recording in the frame.

A short focal length will offer a wide angle, which means that a lot
will be included in the shot. By using a longer focal length, this will
put the lens into telephoto mode, which has a much narrower field of
view. Most lenses will have a fixed focal length, but in the case of
zoom lenses on your camcorder, the focal length will be variable.

Why Does the Focal Length Matter?

When you are shopping around for a new camcorder, you might not be
interested at all in the focal length, however, there are very important
reasons why it matters and why it is important. By learning about the
focal length before you purchase the camera, it will be much easier to
ensure that you are purchasing the right type of camera.

The focal length will tell you about the zoom capabilities of your
camcorder. While this is fairly complicated to learn about, it does tell
you lots of useful information. It also shows you the angles that your
camcorder is capable of capturing.

Measurement

The focal lengths are always measured in millimeters or mm. In
camcorders which have optical zoom fitted, you should see two different
focal length measurements. This is because the focal length will change
depending on the zoom of the camera. There should be one focal length
measurement when the lens is fully zoomed out and another when the lens
is zoomed in.

By using the focal length, it’s possible to do a bit of mathematics
to calculate the magnification of the camera. Simply divide the second
focal length measurement by the first to get the magnification.

For example, a camcorder which has a lens which has a focal length of
35mm when zoomed out and 350mm when zoomed in has an optical zoom of
10x (350 / 35 = 10).
