APO-LANTHAR 50mm F2 Aspherical
The apochromatic design reduces the axial chromatic aberrations of RGB, which comprise the three primary colors of light, to practically zero. This lens pursues ultimate performance utilizing all the technology we have cultivated in the 60 years since Cosina was established and the 20 years since we started manufacturing Voigtländer lenses. This lens combines the highest level of performance for a standard lens in Voigtländer history with compactness and ease of handling.
For Sony E-mount
The lens has electronic contacts to ensure that lens usage data is included in the Exif data of captured images. Furthermore, the built-in distance encoder enables support for 5-axis image stabilization on the body side. Other features include being able to magnify the finder display by operating the focus ring.
Optimized optical design
Provides an imaging circle that covers the 35 mm full frame format and utilizes an optical design optimized for Sony E-mount sensors. High resolution is maintained up to the image periphery and color shifts are well controlled.
Axial magnification chromatic aberrations are extremely well controlled to ensure compatibility modern high pixel count digital sensors.
12-blade aperture diaphragm for enjoying expression utilizing bokeh balls
The aperture diaphragm utilizes a special shape to ensure a circular aperture opening at the maximum aperture of F2 as well as at aperture settings such as F2.8. This enables imaging utilizing bokeh balls of point light sources.
Manual focus for reliable focusing
Employs a very precisely machined and adjusted all metal helicoid unit lubricated with high quality grease to realize smooth focusing operation with just the right amount of torque. This enables very precise focusing.
Aperture click-stop switching mechanism
The aperture click-stop switching mechanism enables the aperture mechanism to be steplessly stopped down/opened up with no click-stop sound. This ensures that the sound of the aperture ring being operated is not recorded while capturing video and also enables a high level of depth of focus control by fine-tuning the aperture ring.
