Construction details of the Summilux-SL 50 f/ 1.4 ASPH.
A notable aspect of its design is the motorized focusing system. Unlike traditional manually focused prime lenses, which often change in length when focusing, the Summilux-SL 50 f/1.4 ASPH. utilizes internal focusing.
To maintain exceptional image quality across the entire focusing range, the focusing group features an intricate construction that includes an aspherical element while remaining lightweight to enable rapid autofocus.
The lens’s optical design comprises 11 elements in total, including two aspherical elements and four made from glass with anomalous partial dispersion, effectively minimizing chromatic aberrations. This sophisticated design reduces both chromatic and monochromatic aberrations to almost imperceptible levels.
Additionally, advanced multilayer coatings on all lens surfaces, an optimized lens tube design, and the rectangular lens hood supplied with the lens work together to minimize reflections and stray light effectively.
