The Camcorder Zoom Lens: The "Swiss Army Knife" of Camera Lenses!
A camcorder zoom lens can be one of the keys to
successful video production as it gives you the ability to work fast and catch all the action...no matter the distance from the subject of your shot!
Find out more on how to use them below…!
A camcorder zoom lens allows you to zoom
in and out on a subject without moving the position of the camera forward or backward. It also enables you to select any coverage within its range to frame and compose your shot.
The zoom feature is usually used when you want to:
Get a closer
shot of the subject or...
You are trying to avoid something at the edge of the picture
coming into the framing of the shot.
It is obviously a lot easier to zoom in on a subject than to move your position closer... Particularly when you are using a tripod and you don't want to break it down and set it up again. In fact, many videographers simply stand wherever it is convenient or where they can get a good view and use it to zoom in or out to vary the size (framing of the shot) or depth of field of the shot.
A Camcorder Zoom Lens is the "Swiss Army Knife" of Lenses!
The Zoom Lens Gives You the Versatility to Capture Almost Any Type of Shot!
One of the best things about a zoom lens is they let you compose the shot and shoot quickly !
* I feel one of the keys to successful videography is the ability to work fast... get the shot as quickly as possible and then on to the next one. A Zoom lens gives you this capability!
the action!! This type of camera lens can help you do that. They
let you frame and shoot very quickly. You can shoot from almost any camera angle or distance and still get a good composition of the shot you want whether the subject your shooting is static or dynamic.
It is the "Swiss Army knife" of camera lenses and if you have a high quality one you will use it often! Believe me!
To get you started here is a short video introduction from RealSEO on the use of the Zoom lens... Enjoy!
Here Are Some Tips for Shooting with Your Camera's Zoom Lens…
Before you shoot take a look at how much of the scene that you're shooting will be sharp and in-focus…? Be sure to take into consideration the depth of field… It will change as you zoom in and out.
The Zoom Lens and Depth of Field
longer (focal length) the telephoto lens is set to... the
less amount of the depth of field
(the distance between the nearest and farthest objects that are in focus) you
will have in the shot... so focus carefully.
What is the background size? How prominent will the background be in closer shots…? Take a close look before you shoot! Below is a nice video by Mike Browne that takes a closer look at using a zoom lens and the effects it has on your images...
using this type of lens the
background in the shot is magnified at the same time as the foreground subject in the shot.
instead of using the zoom lens the camera were moved closer to the subject then the
background size would look different from the zoom shot background size.
you are concerned about the background versus foreground size be careful when using a zoom lens and as Mike Browne says in the above video... "You can always use your feet"!
It's harder to get your shot focused when you're zooming-in with a camcorder zoom lens… So be careful and look carefully at the focus in your shot before you shoot!
The Zoom Lens and Focusing Your Shot
The more you zoom in with your telephoto zoom lens the smaller the Depth of Field is and therefore... the harder it is to get an accurate and sharp focus on the subject that you are
Look out for camera shake if you're zooming in…! The more you zoom in the more susceptible the camera is to the effects of shaking. Be sure to stabilize your camera as much as possible…
The Zoom Lens and Camera Shake
The larger the zoom magnification the cameraman uses...
If you're zooming in you'll need to keep the camera very steady... So consider using a tripod or other stabilizing device.
The accuracy (geometry) of shapes in the shot…? Be on the lookout for distortion of objects in the background and foreground of the camera shot…
The Camera Zoom Lens and the Geometry of Your Shot
Lenses can easily distort shapes. For
example...When a very wide-angle lens is tilted up at a tall building the
building will distort looking as though it is going to fall.
Careful attention must be paid when using a camcorder zoom lens as it is easy to not take into consideration this type of distortion, but you will certainly see it afterwords.
Optical zoom versus Digital zoom? What are they and which of the two systems is best for you?
Digital Versus Optical Zoom – Which One Is Best?
An increasing number of consumer digital video cameras are fitted with a lens system that combines both an "Optical Zoom " and a "Digital Zoom " within the camera.
Zoom " should not be confused with the "Digital Zoom " as there is a very big
A camera might, for instance, have a 20X optical zoom and 100X digital zoom built-in. Depending on the quality of its design the optical zoom system should give a consistently high-quality image throughout its zoom range, in other words the focus and picture clarity should remain optimal at all settings.
This is not always true with the digital zoom part of the system. In a "Digital Zoom" system...
The impression of zooming-in is achieved
by progressively reading out (electronically) a smaller and smaller area of the
same digitally constructed picture. Consequently viewers
are likely to see the quality of the image progressively deteriorating as they
is because fewer and fewer of the original picture's pixels are being
captured and spread across the screen.
line is… Camera lens design in small camcorder zoom lens systems involve many technical
The optical quality of budget digital zoom lens
system is generally below that of an equivalent camcorder with just a prime
lens (fixed focal length) without a zoom.
As you can see...
The camcorder zoom lens needs to be used with some thought and care as the zooming
action can be misused or overused with the possibility of producing distracting and amateurish effects.
Be sure to learn the techniques of
"Zooming" and use
them well... If you do... You'll find that this type of camera lens is one of the most valuable tools you'll have in your camera bag...!!!
