Design Details

The optical configuration includes 12 lenses in 10 groups, three of which are aspherical elements that correct spherical aberration. Many are made of specialised glass elements with anomalous partial dispersion to reduce chromatic aberration using the optics. The close focus distance of 35 cm facilitates detailed close-ups with reliable focusing performance. The lens is made of metal and protected against dust and splash water. Due to its stable construction, a replicable level of quality is guaranteed even after intensive use.
