Are you a shutterbug? Want to take photo with high definition? You should look at this macro extension tube.Look at this macro extension tube if you want to shoot with different depth of field. It has three rings with different dimension of 31mm, 21mm and 13mm. So you can match them freely. An extension tube is an accessory for cameras with interchangeable lenses, used primarily for macro photography. The tube contains no optical elements; its sole purpose is to move the lens farther from the image plane. The farther away the lens is, the closer the focus, the greater the magnification, and also the greater the loss of light (requiring a longer exposure time). Lenses classically focus closer than infinity by moving all optical elements farther from the film or sensor; an extension tube simply imposes this movement. The ring will allow you to use your filter on multiple lenses so you don't have to buy identical filters in various sizes. This is a perfect macro extension tube for Canon D-SLR Camera 7D 5D II 60D 600D. This 3 ring extension tube will be a good assistant for you.Get it now without hesitation! You really deserve to have it! Do not miss it!

How to Use Extension Tubes on a Canon DSLR
Photographers use extension tubes for macro photography. They are available from many different manufacturers for the Canon DSLR. They are a less expensive alternative to dedicated macro lenses that can cost two times the price of a regular lens. An extension tube increases the image size by creating distance between the lens and the sensor of the camera. The EF25 and the EF12 are the two types of extension tubes made by Canon. While the extension tubes are not without limitations, they do provide some interesting effects and are a good alternative for those looking to try their hand at macro photography.
Connect the extension tube to the Canon DSLR body by aligning the red dot on the extension tube with the red dot on the camera body. Turn the extension tube until it locks into place.
Connect the camera lens to the extension tube that is on the Canon DLSR body by aligning the red dot on the lens with the red dot on the camera body. Turn the lens until it locks into place.
Switch the camera on. You can now start trying to focus the lens onto a subject that you want to take close up. Practice first on nonmoving objects such as flowers. Sometimes the autofocus will not work, and you will need to switch to manual focus to help you focus on an image.
How to Use Macro Lenses
Macro photography is the art of capturing detail up close, but first you need the right equipment. A macro lens is a great addition to any photographic setup, and with the right information and approaches can be used to capture tiny objects in immense detail.
Light reflecting in the optics of a camera lens.

If your subject is a nervous butterfly, use a 200 mm lens as opposed to a 50 mm to keep your distance. Greater focal lengths are perfect for macro photography as out-of-focus backgrounds become increasingly soft the longer the lens.

A 50 mm macro lens at a distance of 11 inches (28 cm) from a subject will provide the same image as a 180 mm macro at 31.5 inches (80 cm), except the perspective distortion of the longer lens will widen and further blur the background. This is an especially useful technique for showing living subjects in their natural habitats yet eliminating excessive background detail.
A basic camera tripod.

A tripod will enable the exact setup of a shot and provide a safeguard when shooting in low-light situations where longer shutter speeds are required. For dedicated macro photographers, macro focusing rails move the camera closer or farther away from the subject to allow precise focusing and composition.
A flash unit for an SLR camera.
Flash image by thierry planche from Fotolia.com Use a flash to facilitate higher f-stop values, and a wider depth of field. Often for the level of detail desired in a macro photograph an aperture value of f/11-f/16 is required. With a flash gun utilizing through the lens metering it is possible to light a shot perfectly. It is often recommended to use a flash bracket or to mount the flash off the camera for correct lighting angles.
Use extenders and extension tubes to get the most out of your macro lens. A tele-extender contains optics that increase the focal length of a lens at the expense of light. A 200 mm lens at f/4 would effectively shoot at 400 mm f/8 with a 2x tele-extender. Extension tubes add distance between the lens and the camera, enabling the camera to focus at a closer distance than is otherwise possible. It is not possible to focus to infinity when using an extension tube.
