Optical Design
The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Index Marks
Every index mark is labelled. More detailed markings allow for more detailed focus control.
Focus Movement
Our Academy Award® winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement.
Focus Scaling
Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions. Plus the Entrance Pupil position is engraved on the lens.
Weight/Size Ratio
The lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.
Reliability and Service
S4 prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
