Voigtlander's compact AF prime for Fujifilm X — 41mm equiv at f/2 with electronic contacts and metal build.
The Voigtlander Ultron 27mm f/2 was released in 2023 as a manual-focus prime for Fujifilm X-mount, providing a 40.5mm full-frame equivalent perspective. Electronic contacts enable EXIF data and in-body IBIS communication, but there is no autofocus motor. At 120g and 43mm filter thread it is very compact. Ten aperture blades. 0.25m MFD. One APD element.
The optical design uses 6 elements in 4 groups with 1 APD (anomalous partial dispersion) element. Ten aperture blades. The 43mm filter thread is compact. At 120g the lens is very lightweight. Minimum focus distance of 0.25m. Manual focus only — no AF motor; electronic contacts for EXIF and IBIS communication only. f/2 maximum aperture. APS-C image circle.
The Ultron 27mm f/2 provides a 40.5mm equivalent near-normal perspective for Fujifilm X bodies — slightly wider than normal, suited to street and documentary photography. At 120g it is among the lightest manual-focus primes for the X system. The electronic contacts enable EXIF recording and IBIS cooperation on X bodies with in-body stabilisation, providing stabilised manual focus shooting.
On the used market the Voigtlander Ultron 27mm f/2 is affordable as a compact manual-focus Fujifilm X prime. Condition checks: manual focus ring smoothness, 43mm front element for marks, electronic contact function. Manual focus only — no AF. Compatible with all Fujifilm X-mount APS-C bodies.
