It consists of 11 elements in 9 groups and uses an Aspherical lens element to correct aberration for excellent image quality throughout the zoom range and a circular aperture for exquisite rendering of out-of-focus backgrounds.

它由11片9组，并使用了非球面镜片，以纠正像差优秀的图像质量在整个变焦范围和圆孔的精致呈现失焦的背景。

At present, we now have a capacity of manufacturing over 80 millions pieces of spherical lenses per year with more than 200 sets of precision lens finishing machine.

公司目前拥有200多台套镜片精密加工机器，每年可生产80多万片球面镜片。

Comprising 9 elements and a prism unit in 8 groups, including 1 ED lenses and 5 aspherical lenses with 6 aspherical surfaces, a difficult feat even by today's standards, this advanced lens unit passes Leica's stringent standards to deliver exceptional optical performance to the edges even adopting the folded optics.

包括9片和棱镜组8组，其中包括1 ED镜头镜头和5片非球面镜片6片非球面表面，一个困难的壮举即使按照今天的标准，这种先进的镜头组通行证徕卡的严格标准，以提供卓越的光学性能的边缘即使采用折叠光学。
