Fotodiox Macro Extension Tube Set for Fujifilm Fuji X-Series Mirrorless Cameras for Extreme Close-up Photography

Product Highlights:

Fotodiox Macro Extension Tubes are a wonderful substitution for expensive macro lenses, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.

The camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.

Extension Tubes Overview ¹

An extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor. This additional distance allows your lens to focus more closely, which in turn provides more magnification capability. Unlike most lens accessories, extension tubes don't add any extra optics, and are therefore relatively inexpensive, simple devices.

Note: Diagram assumes that the lens is symmetric (pupil magnification = 1)

An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. For example, adding a 25 mm extension tube to a 50 mm lens will give a magnification gain of 0.5X. Therefore, if the lens's original magnification was 0.15X, then the new magnification will be 0.15X+0.5X=0.65X. The closest focusing distance will also decrease to ~210 mm.

All camera lenses have some amount of native extension, which is used to focus on everyday objects. Lenses with closer focusing distances usually have more native extension, but these will also benefit less from extension tubes. Try experimenting with different lenses to see how extension affects magnification.
