The lens features Panasonic’s Nano Surface Coating technology to minimize ghosting and flaring. The lens also boasts a rugged, dust/splash-proof design and is freeze-proof.
Filter size is 67 mm.
Comprised of 15 elements in 10 groups, the lens system features an aspherical ED (Extra-low Dispersion) lens, three aspherical lenses, two ED lenses and an UHR (Ultra High Refractive Index) lens. The use of these lenses, according to Panasonic, effectively suppresses spherical distortion or chromatic aberration to achieve high resolution and contrast from centre to corners.
The company also notes the new lens excels in video recording performance. In addition to silent operation achieved by an inner focus drive system, the micro-step drive system in the aperture control section helps the camera to smoothly capture brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming, says the company, which also notes the AF tracking performance when zooming is also improved thanks to high-speed frame analysis for focus control.
