The Viltrox AF 23mm f/1.4 Z provides a near-normal 34.5mm equivalent perspective on Nikon Z DX APS-C bodies at f/1.4 — enabling shallow depth of field and low-light performance on the compact APS-C Z-mount bodies (Z50, Z30, Zfc). APS-C only image circle means significant vignetting on Z full-frame bodies in FX mode.
On the used market the Viltrox AF 23mm f/1.4 Z is affordable as an APS-C standard prime for Nikon Z. Condition checks: STM AF response, 52mm front element for marks. APS-C only. Compatible with Nikon Z DX APS-C bodies.
