DZOFILM Vespid 50mm T2.1
Summary
The Vespid Series offers superior image quality with a perfect balance of modern and vintage aesthetics. Its APO design produces sharp and accurate images with minimal chromatic aberration. Vespid lenses excel in optical precision, effectively controlling aberrations for remarkable resolution and true-to-life colors. They create soft and natural bokeh for organic and emotional images with smooth focus transitions, while their internal design minimizes focus breathing. The lenses are fully manual with 270° of focus rotation, giving you smooth and accurate focus control. The shared position of the focus and iris gears across the lens set allows for fast lens changes with minimal adjustment of lens accessories. The focus and iris rings are smooth to operate, allowing for precise adjustments to focus and exposure.
