Voigtlander's reference-class 50mm — the APO-Lanthar with apochromatic correction and electronic coupling.
The Voigtlander APO-Lanthar 50mm f/2 Aspherical is one of the most optically accomplished 50mm lenses ever made. The APO-Lanthar designation represents Cosina's highest optical tier — apochromatic correction that virtually eliminates lateral and longitudinal chromatic aberration. Available in Sony FE and Nikon Z mounts with full electronic communication.
Optical performance is extraordinary. Chromatic aberration is virtually absent at any distance and aperture — a remarkable achievement. Sharpness is outstanding from f/2. Micro-contrast and resolution rival or exceed lenses costing many times more. The rendering is clinically precise yet maintains depth and dimensionality. Focus transition from sharp to out-of-focus is smooth and beautiful.
Available in Sony FE and Nikon Z mounts with electronic aperture and EXIF communication. Filter thread is 49mm — compact. Weight is approximately 364 grams. Build quality is outstanding with precision Cosina engineering in metal and brass. Manual focus only with a smooth, precise helicoid. The electronic coupling makes this significantly more practical than purely mechanical manual lenses.
Available on the used market at moderate prices. Check for smooth focus ring and clean optics. One of the finest 50mm lenses available at any price — the APO-Lanthar optical quality is genuinely in a class of its own. The manual focus requirement is the only barrier. An exceptional choice for photographers who prioritise optical perfection.
