The Rokinon 24mm T1.5 Cine ED AS IF UMC Lens is built for professional video applications with your Micro Four Thirds camera. Its lens construction utilizes 13 optical elements that are placed in 12 groups. Four Extra-low Dispersion and 2 aspherical elements are incorporated into the lens for reducing unwanted distortion. The ultra multi-layer coating ensures clarity by minimizing ghosting and flare. With the 0.8 MOD gear pitch, you can add follow-focus units to the overall rig. The aperture ring is de-clicked to adjust the T-stop value from 1.5 and 22 silently. Moreover, the diaphragm consists of 5 blades that create hexagonal bokeh. The focus and aperture scales are printed on the side to making them easy to refer. You can fit a 77mm filter to the front thread to achieve creative effects.
