Relatively small and lightweight, the DZOFilm VESPID 21mm T2.1 Lens is part of the VESPID series of lenses from DZOFilm and is well suited for independent and high-end full-frame cinematography. The lens has an 80mm front diameter, allowing it to work with virtually any cine-style matte box. The small size makes this lens an attractive option when working with drones and gimbals, as well as when shooting handheld or run-and-gun. The interchangeable PL mount and included EF mount allow you to use the fully manual lens on a variety of modern and vintage cine cameras, while the full-frame coverage supports sensors that have an image circle up to 46.5mm for use on cameras with sensors up to full-frame without vignetting.

The 16-blade iris, which is consistent throughout the VESPID prime lens lineup, creates round out-of-focus highlights that have a more natural appearance and contribute to the lens's natural-looking bokeh. The focus ring features a 270° of rotation for precise focus pulls, and the iris ring a generous 64° of rotation. Cine-style gear rings on the focus and iris rings make the lens compatible with cine-style lens accessories such as follow focus units, lens motors, and lens control systems. The lens has a magnetically attached rear filter for ND filters.
