A fast prime providing a classic portrait-length perspective, the FreeWalker 42.5mm f/1.2 Lens from Mitakon Zhongyi is designed for Micro Four Thirds cameras, where it provides an 85mm equivalent focal length. The bright f/1.2 maximum aperture offers extensive control over depth of field and focus position, and also benefits working in difficult lighting conditions. Its manual focus design is complemented by depth of field and focus distance scales, and a minimum focusing distance of 1.5′ is ideal for working with close-up subjects. The optical helps to maintain a high degree of sharpness, clarity, and color accuracy throughout the aperture range while a metal lens barrel and mount provide enhanced durability and handling during use. Pairing the bright maximum aperture and long focal length, this lens’ ability to isolate subject matter is ideally suited to portraiture and other pictorial applications.
