Constant maximum aperture of T4.4: This means that the lens will have the same amount of light transmission throughout its zoom range, which is important for maintaining consistent exposure when zooming in and out.
Parfocal design: This ensures that focus remains constant when zooming, which is essential for smooth, uninterrupted shots.
9-blade iris: This produces smooth, circular bokeh, which is desirable for creating a pleasing out-of-focus effect.
Click-less iris control: Allows for smooth, silent iris adjustments, which is important for avoiding unwanted noise in your recordings.
Built-in servo: Provides smooth, precise zooming, which is ideal for use in situations where you need to zoom quickly or quietly.
Optional servo grip: Provides added control over the zooming and focusing functions, which is useful for long takes or complex shots.
Lightweight and compact design: Makes the lens easy to transport and use.
Compatible with Super 35-sensor digital cinema cameras: This means that it can be used with a variety of cameras, including the Canon EOS C300 Mark II, EOS C500 Mark II, and EOS C70.
