Together with the\u00a0Leica M11-P,\u00a0Leica\u00a0introduced\u00a0the new generation of its wide-angle prime lens,\u00a0the Summicron-M 28mm F2 ASPH.<\/p>\n

The lens has been updated to take into account the development of new sensor technologies and has an updated minimum focusing distance.\u00a0The previous version of the lens could focus at a distance of 0.7 meters.\u00a0However, the new version, which is still limited to this distance when used as a rangefinder lens, can focus up to 0.4 meters in real time, either when using the Leica Visoflex 2 viewfinder or the Leica FOTOS app.\u00a0Leica notes that when moving into the extended close-up range, the user will feel a “slightly perceptible resistance” when rotating the focusing ring.<\/p>\n

Although at first glance the difference in focusing distance is small, it changes the maximum magnification factor from 1:22 to 1:11.3, which is significant.<\/p>\n

New Leica Summicron-M 28mm F2 ASPH.\u00a0received a built-in hood, the previous version had a removable, rectangular one.\u00a0The diameter of the thread for the filter remained the same – 46 mm.<\/p>\n

\"\"<\/p>\n

The similarities don’t end there.\u00a0The new version has the same number of optical design elements (nine), organized into the same number of groups (six).\u00a0Like its predecessor, the new lens has a single aspherical element.<\/p>\n

\"\"<\/p>\n

In other dimensions, the new lens is similar to the older version.\u00a0The updated Summicron-M weighs about five grams more, possibly due to the built-in lens hood.<\/p>\n

Lens Leica Summicron-M 28mm F2 ASPH.\u00a0features a 10-blade diaphragm, aperture locking ring and classic Leica design.\u00a0It is made in Germany, as evidenced by the engraving on the case.<\/p>\n
