Caruba Extension Tube set - Fujifilm (Version II) The Caruba Extension Tube set consists of two extension rings for Fujifilm X-mount. The rings can be used separately from each other, but can also be combined. The extension rings do not have any optical elements, which makes it possible to bring subjects larger and closer into focus, without negatively affecting the quality of the image. Options such as automatic focus and TTL light metering will continue to work. However, it is advisable to focus manually, because the sharpness is very precise.
Ideal for macro photography
Each lens has a minimum focusing distance. If you place an extension tube, or so-called extension ring, between the lens and the camera body, the minimum focusing distance becomes smaller. The greater the focal length of the extension ring, the closer you can get. This is perfect for macro photography or for taking special close-ups.
