Variants & identification

Variant	Mount	Years	Serial ranges	Production
Summarit-M 90 (11646)	Leica M	2007–2014	4046300–4046501 (Leica Wiki, 2007) 4059505–4059879 (Leica Wiki, 2008) 4125801–4134462 (Leica Wiki, 2009) 4195586–4231806 (Leica Wiki, 2010–2012)	No figure published

The hood was not in the box. Ken Rockwell records that 11646 shipped with a screw-on "thread protection ring" standing in for it, and that the real hood, 12 460, was an extra-cost item at $85 with its own dedicated cap. The dummy ring fouls ordinary 46mm caps and filters if it is left in place, which is how the lens is delivered.
Rockwell's measurements: E46 filter thread, 66.5 × 55 mm, and 344.2 g on his scale against Leica's specified "approx. 360 g". He gives the design focal length as 91.0 mm and the diagonal angle of view as 27 degrees.
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. Leica has published no per-model batch list for the Summarit-M range of the kind that exists for the older Leitz lenses.
The table's Total column is end minus start plus one — the width of the observed span, not a count of lenses. The 2010–2012 row's "36,221+" is 4231806 − 4195586 + 1, and reading it as production would mean Leica built more ninety-millimetre Summarits in three years than it built lenses of all kinds in any year of the general list. The numbers in that span belong to the whole Leica lens output of the period.
The table's footer reads "TOTAL ASSIGNED SERIAL NUMBERS 2007-2014", but its rows stop at 2010–2012. Nothing has been reported to the wiki from the last two years of a lens that stayed in the catalogue until the f/2.4 replaced it in 2014.

Serial-range notes

the seven-digit number on the front ring: The rule. Leica draws Summarit-M numbers from the single sequence it uses for every lens it makes, so a copy is dated against the general Leitz/Leica lens year list rather than against anything particular to this model: 4034901–4057000 is 2007, 4057001–4080000 is 2008, 4080001–4100000 is 2009, 4100001–4115000 is 2010, 4115001–4130000 is 2011, and the published list stops at 4130001 for 2012 (camera-wiki.org, citing Puts's Pocket Pod and Pont's Les Chiffres Clés; Leica Rumors prints the same bands as far as 2009). Above 4130000 no general year list has been published, and the only dates on offer are the Leica Wiki's per-model table, compiled from lenses people have reported rather than from factory records.
the first two digits: Which generation. 40, 41 or 42 is an f/2.5 Summarit-M of 2007–2014; 43 is the f/2.4 that replaced it in 2014. Every f/2.5 number the Leica Wiki records across the four focal lengths falls between 4038014 and 4240378, every f/2.4 number between 4302424 and 4306336, and all four f/2.4 data sheets give the inscription as 43XXXXX.
4046300–4046501: The Leica Wiki's observed span for 2007 — 202 numbers, the narrowest band in the whole Summarit range. It sits well inside the general year list's 2007 of 4034901–4057000, so the two sources agree.
4059505–4059879: The Leica Wiki's observed span for 2008, and again inside the general year list's own 2008 of 4057001–4080000. These first two bands are the last on which the two sources agree.
4125801–4134462: The Leica Wiki calls this 2009. The general year list disagrees flatly, placing 4125801 in 2011 and 4134462 in 2012 — a gap of two to three years. Both are recorded here.
4195586–4231806: The Leica Wiki's 2010–2012 span, and the last numbers it records for this lens although it stayed in the catalogue to 2014. The band sits far above the end of the general year list, so no independent date check exists for it. Its lower end, 4195586, is flagged on the wiki as reported stolen.

What reviewers say

Ken Rockwell (blog) — Rockwell rates the optics superb and the equal of the Elmarit-M 90 and the APO-Summicron, but bought one and returned it over the mechanics — a rubber focus grip, uneven focus feel and a font Leica does not use on its own lenses — and concludes that better used lenses cost less money.
Steve Huff (blog) — Huff recommends it without reservation as the 90mm solution for an M, reporting that it focused reliably where several Summicron copies would not and that its results matched the discontinued Elmarit-M 90.

History

The 90mm Summarit arrived in 2007 and the Elmarit-M 90 left the catalogue in the same period, which is the whole story: Leica replaced its ordinary 90 with a cheaper one and moved the Elmarit’s role down a tier.

Five elements in four groups — one fewer than the other three lenses in the range, which all use six in four — at f/2.5 and a metre minimum focus.
