S4 Quality Deserves the S4 Name
The miniS4/i lenses incorporate everything in that today's filmmakers ask for: smaller, lighter weight prime lenses that offer the same resolution, optical quality and reliability as the S4/i prime lenses but at a lower price - and, the miniS4/i 35mm lenses are interchangeable for shooting film and digital images up to and beyond a 4K resolution.
miniS4/i prime lenses are available individually in focal lengths: 18, NEW 21, 25, 32, 40, 50, 65, 75, 100 and 135mm. The miniS4/i lenses are also available in sets.

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.
