    M 90mm F1.5 ASPH. Lens

    Recently, Leica released the SUMMILUX-M 90mm F1.5 ASPH. Lens. This M-mount lens includes 8 lens elements in 6 groups, two of which are aspherical and made of special glass. It is reported that the Leica SUMMILUX-M 90mm F1.5 ASPH. Lens National Bank sells for 93,000 yuan, and has been on sale on December 12.

    The Summilux-M 90 f / 1.5 ASPH. Lens has a focal length of 90mm and an amazingly large aperture, fully exploiting the potential of the Leica M mount. In terms of optical design and aesthetic rendering, the latest Summilux-M lens is very similar to the Noctilux-M 75 f / 1.25 ASPH. Lens. For example, both lenses exhibit sharp razor-like in-focus imaging with a depth of field only half the depth of the legendary Noctilux-M 50 f / 0.95 ASPH. Lens.

    The MTF technical data sheet shows that even at the maximum aperture, regardless of the distance of the subject, this lens can provide ultra-high contrast, present wonderful details, and the image quality at the edges is almost not damaged. For this kind of fast lens, the maximum magnification can reach 1: 8.8 at the closest focusing distance of one meter, which means that the photographer can get close to the subject sufficiently to capture the ideal portrait work.
