BESSEY SQ-12 12 in Bar Clamp Steel Handle and 5 1/2 in Throat Depth

A truly fast and compact prime, the Speedmaster 25mm f/0.95 Lens from Mitakon Zhongyi is compatible with Micro Four Thirds mirrorless cameras, where it presents a 50mm equivalent focal length. The bright f/0.95 maximum aperture is well-suited to low-light shooting and also offers extensive control over your focus position for shallow depth of fiel... mored applications. One extra-low dispersion element is incorporated within the lens construction, as well as four extra-high refractive index elements and two high refractive index elements, to limit chromatic aberrations and distortions for a high degree of clarity and sharpness throughout the aperture range. Additionally, optimized lens coatings have been applied to limit lens flare and ghosting. The physical construction of the lens revolves around its manual focus design, which is complemented by printed depth of field and distance scales for zone focusing techniques. The manual aperture ring also features a click-less design for silent, smooth operation that is beneficial to video recording applications. Additionally, an eleven blade near-circular diaphragm produces a smooth out-of-focus quality when working with selective focus techniques.
