Lens Leica APO-Summicron-SL 35mm f/2 ASPH, Leica L mount, black

The new APO-Summicron-SL prime lens delivers extremely high image performance at maximum aperture and is ideal for shooting in difficult lighting conditions. Its design includes 13 extremely complex lenses which provide the highest level of image quality so typical of Leica: natural skin tones, soft bokeh transitions Excellent detail contrast and consistent sharpness throughout the entire image without any distortion. For SL lenses, the following is generally true: the maximum aperture is operational - decreasing the aperture is purely a creative shooting tool and is not necessary to achieve the best optical performance of images. All glass elements of the optical system, such as lenses refract light of different colors to varying degrees. This leads to that not all light rays from a multi-colored object are focused at one point in the image leading to chromatic aberration. In the new APO-Summicron-SL 35 mm, f/2 lens ASPH minimizes these chromatic aberrations through apochromatic correction. For this, most of the thirteen lenses used in the lens five of which have aspherical surfaces are made from specially developed high quality glass types with anomalous partial dispersion that push Leica's innovative production methods to the limits of technical capabilities. The design and design of the cutting-edge APO-Summicron-SL lens line represents another step forward in the development of lenses for Leica SL cameras. New lenses were developed specifically for the production of these lenses. extremely precise production and measurement methods. The result of this is not only more compact dimensions and noticeably lighter lenses but also excellent image characteristics. APO-Summicron-SL lenses have been designed with special attention to preventing stray light and reflection. High-quality lens coating, along with optimization of optics and mechanics Reduces inevitable reflections to an absolute minimum. Thanks to effective dust insulation , moisture and water splashes as well as Aqua
Dura coating on the exposed surfaces of the lens It can be used without hesitation in almost any weather conditions. The autofocus drive of all Summicron-SL lenses uses extremely powerful and reliable DSD (Dual Syncro Drive) stepper motors.. Thanks to this, the entire focusing process is completed in approximately 250 milliseconds. Leica demonstrates its innovative capabilities not only with regard to autofocus technology but also regarding manual focusing. APO-Summicron-SL lenses feature a completely new manual focusing concept in which a variable magnetization ring magnet is built into the focusing ring. The magnetic field changes its polarity when the ring is rotated. The sensor monitors the state of the magnetic field and sends data about it to the main processor. The actuator then moves the lens to the appropriate focusing position based on the rotation angle and rotation speed; This , in turn, provides faster and more accurate manual focusing.
