The 40mm lens has an image circle that covers a full-frame sensor. When mounted on a camera with a Super35 sensor, it provides you with a tighter shot than if mounted on a camera with a full-frame sensor. VESPID 40mm 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.
