The Rokinon 24mm T1.5 Cine ED AS IF UMC Lens for Micro Four Thirds Mount is designed especially for DSLR video enthusiasts, videographers and cinematographers to offer a wide-angle perspective equivalent to 48mm on the 35mm format. It’s front filter thread accepts 77mm filters and like Rokinon’s other Cine lenses, it has a solid build, clickless aperture and geared rings. The optical construction incorporates four Extra-low Dispersion elements, as well as two aspherical elements, to reduce chromatic aberration and distortion to produce sharper imagery. UMC coating has been applied to lens elements to improve light transmission and create a more contrast-rich image.
