Extension tubes are a way of extending the length of your existing lens. Camera extension tubes fit between the body of the camera and the built-in lens and will make your lens appear longer than it previously was. The main purpose of them is to aid the photographer in moving closer to an object, while at the same time being able to keep a steady focus.
You will have all experienced occasions when your camera is simply unable to cope with the closeness of an image and extension tubes can help put paid to situations such as this. Accessorising your camera can sometimes have a negative impact on image quality, but camera extension tubes will have the opposite effect as they can actually help improve the amount of detailing in a photograph and enhance magnification significantly.
Canon extension tubes and Kenko extension tubes are not only designed for cameras of the same brand, but are also interchangeable with many different makes of lens. All you have to do when adding them to your camera is to remove the existing lens, attach the extension tube to the body of the camera and reattach the lens.
Although an extension tube may take away your ability to use auto focus, they will allow you to snap fantastic shots and will offer you the reliability you need from any form of optical equipment. The full range of camera extension tubes can be viewed in your local Wilkinson Cameras store.
