Variants & identification

Variant Mount Years Serial ranges Production
Black (11684) Leica M 2014 up to 4306316 (Leica Wiki, 2014; highest black reported, no lower bound given) No figure published
Silver Leica M 2014 4306336 upward (Leica Wiki, 2014; lowest silver reported, no upper bound given) No figure published
  1. A change that is not on the data sheet: Steve Huff records that the f/2.4 revision ships with the metal hood and leather case in the box, where the f/2.5 sold both as accessories. On a range whose optical change is a tenth of a stop, the packaging is a real part of the revision.
  2. Eleven aperture blades and a 46mm filter thread β€” the same thread as the Summilux-M 50mm ASPH, so the two share filters (Finding Range).
  3. The US list is quoted at two figures four years apart: $2,350 at launch in 2015 (Steve Huff) and $2,195 in 2019 (Finding Range). Neither is a Leica price list; the entry records the launch figure.
  4. The Leica Wiki's serial table is headed "Serial numbers compiled from known lenses". It is a record of observed extremes, not a factory batch list: each row's start carries a leading dash and its end a trailing dash, meaning the true bounds lie at or beyond the numbers printed. Both of this lens's rows have one end marked "unknown", and both its Total cells read "unknown". Leica has published no batch list for the Summarit-M range of the kind that exists for the older Leitz lenses.
  5. The Leica Wiki records numbers from 2014 only. The range was withdrawn in March 2020, so something over five years of production is unrepresented in the published serial data altogether.
  6. The four f/2.4 Summarits were numbered in two clusters, not one. The 35 and the 50 sit within about seventy numbers of each other at 4302424–4302495; the 75 and the 90 sit within about fifty at 4306287–4306336, some 3,800 numbers later. Those gaps are filled by whatever else Leica was numbering at the time, since all its lenses share one sequence.
How to tell them apart (expand)
  • f/2.4 rather than f/2.5 β€” a tenth of a stop, and the only specification change on some of the range
  • Minimum focus improved from 1 m to 0.9 m

Serial-range notes

the seven-digit number engraved on the front
The rule, and where it stops. Leica draws Summarit-M numbers from the single sequence it uses for every lens it makes, so a copy would ordinarily be dated against the general Leitz/Leica lens year list β€” but that list runs out at 4130001 for 2012 (camera-wiki.org, citing Puts's Pocket Pod and Pont's Les Chiffres ClΓ©s), and every f/2.4 number reported so far stands above 4300000. No published year list reaches this generation. The Leica Wiki's table records numbers from 2014 alone, the first year, and none from the further years the lens was sold, so a serial identifies an f/2.4 Summarit and its finish but not its year.
the first two digits
Which generation. 43 is an f/2.4 of 2014 or later; 40, 41 or 42 is the f/2.5 Summarit-M of 2007–2014 that this lens replaced. Every f/2.4 number the Leica Wiki records across the four focal lengths falls between 4302424 and 4306336, every f/2.5 number between 4038014 and 4240378, and all four f/2.4 data sheets give the inscription as 43XXXXX.
4306316 and 4306336
The highest black and the lowest silver 90mm f/2.4 the Leica Wiki records, twenty numbers apart and both from 2014. The two finishes were therefore numbered together in one run rather than allotted separate blocks β€” the boundary is where the reported examples happen to fall, not a factory division. 4306336 is the highest number recorded for any Summarit-M of either generation.
4306287–4306336
The 90 was numbered alongside the 75, in a block about 3,800 numbers above the one holding the 35 and the 50. A 90 and a 75 whose numbers are fifty apart are effectively the same week's work.

What reviewers say

History

In 2014 Leica replaced all four Summarits with lenses a tenth of a stop faster. f/2.5 became f/2.4, which is the smallest generational change anywhere in this catalog and close to meaningless photographically β€” a tenth of a stop is below the tolerance of most shutters.

What actually changed varies by focal length, and on this one the minimum focus is improved from 1 m to 0.9 m. The Leica Wiki’s own data sheets mark the differences from the previous version in red, which is the clearest sign that the differences needed pointing out.
