Eleven elements in 8 groups (1 Super High Refractive + 1 aspherical element). Ten aperture blades. The 58mm filter thread. At 571g the lens is heavy for an MFT prime. Minimum focus distance of 0.23m. Manual focus only. f/0.95 maximum aperture. MFT image circle (85mm equivalent). Micro Four Thirds mount.
The f/0.95 aperture at 85mm equivalent provides the shallowest depth of field achievable on the MFT system: on a 2× crop sensor, f/0.95 provides approximately full-frame f/1.9 equivalent depth-of-field. The 571g weight is substantial for MFT but typical for ultra-fast manual prime designs. Manual focus only — there is no autofocus version of the Voigtländer Nokton 42.5mm f/0.95.
On the used market the Voigtländer Nokton 42.5mm f/0.95 is available at premium MFT manual prime pricing. Condition checks: focus helicoid smoothness (should be damped), 58mm front element for marks. Manual focus only. Compatible with all Micro Four Thirds bodies.
