Do you want to turn your lens into a macro lens? Do you want to focus lenses on most MA Body manually? This Extension Tube maybe meet all your needs! Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.

  • Specifications:

    • Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance
    • It moves the lens farther from the film or digital sensor
    • The farther away the lens is, the closer the focus, the greater the magnification
    • A close up filters are often blamed for degrading image quality
    • It is mounted in between the camera body and lens to create more distance between the lens and film plane
    • Size: 68 x 62mm / 2.7 x 2.4in(H x Dia.)

    • They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality

    NOTE:

    • When using extension tubes the lens will not focus to infinity. The focus range will be greatly limited to a very close focusing distance
    • There is light fall off when using any extension tube, sometimes the equivalent of 3 f-stops of light is lost when using multiple extension tubes together. This light lost can affect the camera's ability to auto focus. Manual focusing is recommended should the lens begin to "hunt" (not lock onto the subject)

    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
