Tokina's compact fast prime for Fujifilm X — 35mm equivalent at f/1.4 with smooth focus ring.
The Tokina atx-m 23mm f/1.4 is an autofocus APS-C prime for Fujifilm X-mount bodies, providing a 35mm full-frame equivalent perspective at f/1.4. The ST-M (Stepping Motor) provides fast, near-silent autofocus suited to video recording. A clickless aperture ring enables smooth, noise-free aperture transitions during video. At 276g and 52mm filter thread it is compact for an f/1.4 APS-C prime. The 35mm equivalent covers street photography, documentary, and available-light shooting.
The optical design uses 11 elements in 10 groups. Nine aperture blades produce smooth bokeh. The 52mm filter thread is compact. At 276g the lens is lightweight. Minimum focus distance of 0.3m. ST-M stepper motor provides fast, near-silent AF. Clickless aperture ring enables smooth video aperture transitions. f/1.4 maximum aperture. APS-C image circle.
The clickless aperture ring is the atx-m 23mm's defining video feature: a clickless ring enables smooth, gradual exposure transitions during recording without the discrete clicks of a standard aperture ring that would appear as sudden exposure jumps in footage. The ST-M motor's near-silent operation avoids AF noise in video audio tracks. At f/1.4 and 35mm equivalent on APS-C, the lens provides the classic street-photography focal length at maximum fast-aperture performance.
On the used market the Tokina atx-m 23mm f/1.4 is affordable for an autofocus f/1.4 APS-C prime. Condition checks: ST-M AF motor response, 52mm front element for marks, and clickless aperture ring smoothness. Compatible with Fujifilm X-mount APS-C bodies.
