The constant maximum iris of T4.4: This means that the lens will have the same amount of light transmission throughout its zoom range. This is important for maintaining consistent exposure when zooming in and out.
The parfocal design: This ensures that focus remains constant when zooming. This is essential for smooth, uninterrupted shots.
The 9-blade iris: This produces smooth, circular bokeh. This is desirable for creating a pleasing out-of-focus effect.
The click-less iris control: This allows for smooth, silent iris adjustments. This is important for avoiding unwanted noise in your recordings.
The built-in servo: This provides smooth, precise zooming. This is ideal for use in situations where you need to zoom quickly or quietly.
The optional servo grip: This provides added control over the zooming and focusing functions. This is useful for long takes or complex shots.
Compatible with Super 35-sensors: 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.
