Panasonic Lumix S Pro 70-200mm F2.8 O.I.S.
Designed and developed for professional field shooting, the LUMIX S PRO 70-200mm F2.8 O.I.S. uses 2 UED (Ultra Extra-low Dispersion) lenses, 3 ED (Extra-low Dispersion) lenses and optimum alignment comprising 22 elements in 17 groups, effectively suppressing both axial chromatic aberration and chromatic aberration of magnification. Astigmatism is also corrected with an aspherical lens, achieving high resolving performance. Adoption of a double focus system suppresses fluctuation of aberration even at close distances, which results in high descriptive performance from the center to the corners over the entire zoom range despite its large aperture.
