A comfortable and compact wide-angle prime, the Color-Skopar 21mm f/3.5 Aspherical from Voigtlander is a Sony E-mount lens well-suited for landscapes, nature, and other wide-field subjects. Its optical design includes one aspherical element and one low dispersion element, which help to minimize both spherical and chromatic aberrations in order to achieve a high degree of sharpness, clarity, and color accuracy. The manual focus design affords fine-tuned control over focus placement, along with a minimum focusing distance of 7.9" and a 10-blade diaphragm is also used for a smooth bokeh quality.
