Leica released the M lens with the best optical performance so far-Leica APO-Summicron-M 35 f/2 ASPH. lens. Like the previous successful Leica APO-Summicron-M 50 f/2 ASPH. lens, this time Leica’s product designers still adhere to the principle of “creating the ultimate imaging performance without compromising”, but the difference is that , The new lens introduced this time uses a wide-angle 35mm focal length. This lens with sharp imaging details not only focuses on the present, it can even match the photosensitive elements of the future. In addition, the Leica APO-Summicron-M 35 f/2 ASPH. lens is the only lens in the M series that has the closest focusing distance as close as 30 cm. Together with its excellent performance under extreme light conditions, it provides creators with Opens up more possibilities.
Such excellent performance is inseparable from the precise structure of the lens design and the high-precision manufacturing process of the Leica Camera Factory. The 10 optical lenses are arranged in 5 lens groups-3 of which are aspherical lenses (1 of the 3 is a double-sided aspherical lens). The 6 optical lenses are made of special glass with local dispersion performance, which not only reduces chromatic aberration to almost zero, but also provides apochromatic correction capability, making it one of the few with apochromatic apochromat in the 35mm focal length. One of the shots.
Thanks to the floating lens group that can ensure consistent high-quality performance of the lens in all focusing distance ranges, the Leica APO-Summicron-M 35 f/2 ASPH. lens can also provide excellent imaging in close-up shooting. The focus ring can be rotated within a 300° precision focus ring rotation range, ensuring precise focus even when the focus distance is shortened. When using the viewfinder yellow spot to focus, the closest focusing distance of the lens is 1750px. When the focus ring is rotated to this point, a slightly different damping will be felt. Between the focusing distance of 1750px to 750px, the photographer can control the focus through the camera display in the live view mode, the Visoflex electronic viewfinder or the Leica FOTOS application.
The innovative structure of the lens hood and the efficient anti-reflection coating make the Leica APO-Summicron-M 35 f/2 ASPH. The lens is sufficient to withstand any type of stray light, and the photographer can shoot directly at daylight or other light sources. Not only that, but optical defects such as chromatic aberration and distortion are almost completely corrected. Coupled with extremely high-contrast edge imaging, together they create excellent out-of-focus imaging quality at the maximum aperture. Thanks to the use of 11 blades, the aperture is almost round, so even if the aperture is reduced, the image quality is still not compromised.
When creating with a Leica M lens, there is no need to narrow the aperture to improve the image quality, but completely out of composition needs. This advantage is more prominent on the Leica APO-Summicron-M 35 f/2 ASPH. lens. At the maximum aperture, the image quality at the center and edge of the image is already excellent, so there is no need to reduce the aperture to improve the image quality. Under the premise of such excellent performance, the Leica APO-Summicron-M 35 f/2 ASPH. lens is compact and lightweight. With a classic documentary focal length, this lens is capable of shooting in any situation. The Leica APO-Summicron-M 35 f/2 ASPH. lens is suitable for current and future Leica M series cameras, and can also be used with Leica SL2 and SL2-S cameras.
