The Viltrox DG-FU Extension Tube Set gives you two tubes — 10mm and 16mm — that mount between your Fujifilm X-mount lens and camera body to reduce the minimum focusing distance and enable macro-style close-up photography without buying a dedicated macro lens.
What extension tubes actually do
Extension tubes work by physically moving the lens further from the sensor, which shifts the focusing range closer to your subject. The further the lens sits from the sensor, the closer you can focus — so stacking both tubes together gives you maximum magnification. There's no glass involved, so optical quality stays entirely with your existing lens.
The DG-FU set maintains electronic contacts, meaning autofocus and aperture control continue to work through the tube — handy when you want to use AF for live-view focusing on still subjects. Manual focus is still the go-to for precise macro work, but having the electronic connection keeps your shooting workflow familiar.
Both tubes can be used individually or combined. The 10mm tube gives a moderate close-focus boost, the 16mm pushes further, and stacking both at 26mm total gives you the most dramatic magnification your lens allows. Shorter focal lengths benefit more from extension, while longer telephoto lenses need more extension to achieve similar results.
Who is this for?
This set suits Fujifilm X shooters — whether you're using an X-T, X-S, X-Pro or X-H body — who want to explore macro photography without committing to a dedicated macro lens. It's a compact, affordable way to repurpose lenses you already own, especially primes like a 35mm or 50mm. Find more Viltrox accessories to complement your kit.
Buying a used set makes particular sense here: extension tubes are purely mechanical with electronic contacts, so wear is minimal and function is straightforward to verify. At Camera-tweedehands.nl, every extension tube set is hand-inspected for mount integrity and electronic contact function. Every item comes with a minimum 12 months warranty.
