Variants & identification

Variant Mount Years Serial ranges Production
Black (11668) Leica M 2015 — No figure published
100 Years edition, silver Leica M 2015–2015 — 101 lenses, numbered 1–101
  1. Leica's own technical data sheet gives the lens as approximately 81 mm long, 61 mm at its largest diameter and approximately 440 g, on an E49 filter mount, with a screw-in hood supplied. Seven of the ten elements are in glasses of anomalous partial dispersion and one carries the aspherical surface; a further element towards the rear is a floating element that moves independently of the rest of the mechanism to hold performance at the 0.7 m close limit.
  2. The same sheet publishes the aberration figures: maximum vignetting at full aperture of about 3.4 stops in the corners on 35mm format, falling to 1.8 stops at f/5.6, and maximum distortion of 1.1 per cent pincushion.
  3. No serial list has been published for this lens. The Leica Wiki's serial section carries a single row with unknown at both ends, dated 2015, and a TOTAL row that also reads unknown — and that one row captions the product Summicron-M rather than Summilux-M. No production figure has been published either. Of the four f/1.4 wide-angles, this is the one about which the record says least: a lens that can be dated only by its own announcement, on 21 May 2015.

Serial-range notes

the seven-digit number on the front ring
The rule for every Leitz and Leica lens: the numbers run in one running sequence shared across models, so a serial normally gives an approximate date — but the sequence does NOT begin at 100,000 in 1931, and a serial usually identifies the model too. The register behind the published year list records reserved BLOCKS, each entered with a date, a range and a lens name, which is why per-model batch tables exist and why they are the better evidence where the two disagree. The date is when the block was reserved, not when the lens was finished. Date a copy by the year band it falls into — except that for this lens the general list runs out before the lens begins. Its last published band opens at 4,130,001 for 2012, three years before this lens was announced, so every copy falls past the end of the list and the year list cannot date one at all.
4XXXXXX
The only serial information the Leica Wiki records for this lens, given as part of the engraving pattern: LEICA SUMMILUX-M ASPH. 1:1.4/28 E46 followed by a seven-digit number beginning with 4. That places it in the same continuous sequence as every other Leica lens of the period and says nothing more.
1–101
The numbers engraved on the 100 Years silver edition are edition numbers, not serial numbers: the lens carries both, and a copy marked 37 is the thirty-seventh of 101, not lens number 37. No serial range has been published for the edition.

What reviewers say

History

The 28mm Summilux completes the set. Leica introduced f/1.4 at 21mm and 24mm in 2008 and finished the line here in 2015, giving the M mount fast lenses from 21mm to 75mm — something no rangefinder system has ever had.

Ten elements in seven groups, 75 degrees at full aperture, focusing to 0.7 m. A silver edition of 101 lenses, numbered 1 to 101, marked the centenary of the Ur-Leica: Leica dates itself from Barnack’s 1914 prototype, which is why its anniversaries fall where they do and why an earlier generation of editions was marked 1913–1983.
