The zoom range of the Panasonic Lumix G Lens 12-35mm F/2.8 LEICA covers wide angle, normal and short telephoto, making it ideal as an all-round lens.
Advanced autofocus
The Leica DG Vario-Elmarit 12-35mm / F2.8 ASPH. / POWER O.I.S. is capable of smooth, silent operation to work with the camera’s high-speed, high-precision contrast AF system with the sensor drive at a maximum 240 fps. It also excels in video recording performance with a mechanism that suppresses focus breathing, which was a fatal problem of all interchangeable lenses designed for still image photography. This mechanism and the micro-step aperture control for smooth exposure change achieve professional quality video recording. Combining with the camera’s Body I.S. and the lens’ O.I.S., Dual I.S. 2 provides effective hand-shake correction.
Optical construction
The Leica DG Vario-Elmarit 12-35mm / F2.8 ASPH. / POWER O.I.S. is comprised of fourteen lens elements in nine groups including four aspherical lenses, one UED (Ultra Extra-Low Dispersion) lens and one UHR (Ultra High Refractive Index) to achieve high optical performance. The Glass material of the UHR lens element has been updated to that of higher transmittance to achieve even more natural color reproduction. Panasonic’s unique Nano Surface Coating provides effective antireflection coating that assures clear description.
By applying thin coating with nanometer-level microstructure that features an ultra-low dispersion ratio, the reflection of the entire wavelength of 380-780 mm including visual light range are reduced. Together with a newly adopted light-shieling part, occurrence of ghost and flare is minimized.
Rugged design
The external design has been refined to be worthy of its LEICA name. With its approximately 306 g compact size and light weight, the Leica DG Vario-Elmarit 12-35mm / F2.8 ASPH. / POWER O.I.S. features stunning mobility that Micro Four Thirds system boasts. The rugged dust/splash-resistant design withstands use under harsh conditions even at 10 degrees below zero for high mobility. The filter diameter is 58 mm, with a 7-blade circular aperture diaphragm.
