    What is an Extension tube?

    • 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.
    • Extension tubes without electrical contacts will not allow an electronic automatic camera to control the lens, thus disabling autofocus and in some cases forcing a user to shoot wide open unless the lens offers manual aperture control. More expensive extension tubes contain electrical contacts allowing the user to use autofocus and electronically control the aperture of the attached lens.

    How to Use an Extension Tube?

    • An extension tube for a telescope or other optic acts between the objective lens and the eyepiece of the instrument by spacing and funneling light. Extension tubes affect focus capability by moving the lens within the eyepiece further from the mirror within the telescope.
    • Instructions:
    • Select the object you want to view, such as a galaxy, a specific star or a feature of a certain planet. This will give you an idea of the field of view you need to achieve.
    • Decide on the optical effect you wish to attain via focus, such as enhancing detail on the moon's surface or bringing a distant star into sight.
    • Get some advice from your telescope manufacturer's instruction manual, astronomical literature or through astronomer or optics shop contacts on how much focal extension to shoot for. This will tell you which length of extension tube to select.

    Achieve the Right Tube Effect:

    • Loosen the clamp or thumbscrew that secures the telescope eyepiece.
    • Remove the eyepiece from its mount on the telescope body and set it in a safe place.
    • Insert the extension tube on the telescope accessory mount and tighten the clamp or other locking device.
    • Attach the telescope eyepiece to the free end of the extension tube and secure it with its locking device. Since attachment of eyepieces to extension tubes varies widely by model, it's very important to carefully follow your manufacturer's instructions during this process to avoid damaging the telescope.
    • Experiment and use different tube lengths under different light conditions to discover the right focus for your viewing objective.

    Tips & Warnings:

    • Extension tubes typically come in a range of diameters and lengths. They usually attach at the T-mount site in front of the eyepiece.Trial and error are unavoidable when using extension tubes. Experience will help you determine which length of extension you will need to use in order to achieve the desired focus.Extension tubes are also used with 35mm cameras to enhance the focus for still or macro photography.
    • You can most likely get one specifically designed for your camera though the manufacturer.Metal or plastic extension tubes have no lens components, so they represent an economical investment with a demonstrative effect on astronomical or other viewing.
    • An extension tube is not a magnifier and should not be used in place of an eyepiece.An extension tube provides no "white light" solar protection. You will still need to use a specially made solar filter in order to safely view solar eclipses

Cheap alternative to new lens
09:33:21 01-27-2012
Great alternative to buying a new macro lens, five different length's allow for different magnification. Super close photos can be achieved using all of the rings, less than 1cm to objects.

None!

Not bad for the Price
00:00:00 01-26-2012
This Camera Extension Tube isn't to bad for the price. I am a beginner and still learning. You do have to get very close to use this. So if your just learning, I would say this would be the best bet until you get things figured out.

Can't beat this item for the price
00:00:00 01-22-2012
For the price this product is great. I agree with others that instructions should be included when you receive the product. Just takes some experimenting to learn how to use. Having the lens wide open hasn't really been a problem and shouldn't be for most users who combine this with a F4.5 or above. I'm very happy with this purchase and recommend this item to anyone who is looking to experiment with macro photography. It's now in my bag wherever I go.

Does exactly what it is supposed to do
00:00:00 01-20-2012
You will not be able to use these with autofocus but it really shouldn't matter because the depth of field is razor thin and you will need to manually focus anyway to get your desired shot. All they do is block light and extend the lens out from the body in order to achieve the magnification at the reduced distance. Pretty simple. They seem to have decent enough quality to last.

Useful Lens Extension Tube
00:00:00 01-18-2012
I read few reviews about this product and then ordered it. I have used it with my canon with 18-55mm and 55-250mm lens. Considering the price it is an excellent bargain. You cannot use autofocus and aperture control. Aperture is manageable once you set its value, use DOF button and detach lens at the same time. It leaves the aperture there. I took pictures of icicles from window, in daylight, handheld across the window glass. It gave me marvelous results. I high recommend this product for those who want to save money and can play around with things manually.

Camera Extension Tube
00:00:00 01-12-2012
This Macro Extension Tube was an easy purchase. I was looking for a way to take close up pictures of small items. This item was well described and pictured. I knew it would fit my camera and lens as it was stated in the description. It was shipped quickly and was well packaged. I was very satisfied with the purchase and would recommend it to anyone looking for such an EOS accessory.
