This makes on-set lens changes a fast and efficient operation.

It features a maximum T stop of 1.5, which is useful when shooting in low-light situations or when you want to capture that exceedingly shallow depth of field look.

The Cinema Vista Prime lenses are designed to minimize focus breathing and feature geared, manual focus and iris rings. Markings on both sides of the lens barrel make it readable from either side of the camera.

The 21mm T1.5 Canon EF mount prime lens focuses images on a sensor with full 8K resolution and features a 46.7mm image circle, which easily covers standard-sized full-frame sensors.

The use of a 9-blade iris produces a smooth, round appearance to out-of-focus specular highlights. The iris also produces a pleasing bokeh, referring to natural-looking out-of-focus areas of the image. The iris is manual and features smooth movement without click stops for smooth exposure adjustments while recording.

The lens has markings on both sides of the barrel, making it easy to read focus and aperture settings from behind or from either side of the camera.

The lens shares the same front lens diameters and gear positioning on the focus and iris rings as the other lenses in the series, making lens switching quick and convenient.

It is designed to minimize variations in the angle of view while focusing, a phenomenon known as focus breathing. This feature is extremely important while pulling focus, especially on static shots, where focus breathing is more noticeable.

The lens features threading on the front of the lens to accommodate 112mm screw-on filters. This feature allows the camera operator to add filters over the lens without taking up a filter stage in a matte box.
