  1. Element and group counts, weights, closest focus, exact focal lengths and filter series are from the Zeiss data sheets hosted by Hasselblad Historical (C40, CF40, CFE40, CFE40IF).
  2. Generation start years follow the barrel/shutter families (C 1967 for this focal length, CF 1982, CFE 1998); the black and T* changeovers are undated for the 40 specifically, and the 2003 IF date is from dealer chronologies.
How to tell them apart (expand)
  • Three optical designs under one name: 10/9 in every C lens (1967–82); 11/10 with a two-ring floating front group in the CF and CFE FLE (1982–2003); 12/9 with internal focusing in the CFE IF (2003–13)
  • Filter mount sorts C from later: bayonet 104 on every C lens, bayonet 93 on CF, CFE and CFE IF
  • Two focusing rings (rear continuous, front three-position) mean CF or CFE FLE; one ring on a Prontor-shutter 40 means the IF lens; one ring with a Synchro-Compur EV lever means a C
  • Red T* on the name ring from 1973/74; chrome barrels are always pre-T*
  • Only the CF, CFE and CFE IF have the green F setting and can be used open-shutter on a 2000/200-series body

Distagon C 4/40, chrome (1967 baseline):

  • Satin-chrome barrel, engraved Carl Zeiss / Distagon 1:4 f=40mm; no T* mark; single coating
  • Synchro-Compur with the EV interlock lever — aperture and speed rings move together until the cross-coupling lever is pressed
  • Bayonet-104 filter mount, the largest in the C line (Zeiss data sheet: 'bayonet for Hasselblad series 104'); about 1375 g
  • Click stop on the distance ring at 0.9 m that has to be pushed past to reach 0.5 m — the data sheet says it is there to remind the user to stop down at close range
  • Red-ink Zeiss date code inside the rear mount — pre-1980 the last two digits are the month and the leading digit(s) plus 1957 the year

Distagon C 4/40, black (non-T*):

  • Black-anodised barrel with the same C-type engraving, EV lever and bayonet-104 mount as the chrome lens; no red T*
  • Same 10/9 optics and 1375 g as the chrome lens — the change is finish only

Distagon C T* 4/40:

  • Red T* after the Distagon name; black barrel; bayonet-104 filter mount; EV interlock lever; 0.9 m click stop retained
  • Zeiss data sheet: cat. no. 104163, 10 elements in 9 groups, 1375 g, 0.5 m closest focus, Compur size 0 with automatic diaphragm

Distagon CF T* 4/40 FLE:

  • Two focusing rings: the rear one runs ∞–0.5 m continuously, the front one has three click stops (∞–2 m, 2–0.9 m, 0.9–0.5 m) that reposition the front pair — the FLE (Zeiss data sheet)
  • Prontor CF shutter in a black barrel with rubber focusing grip; green F on the speed ring; EV interlock as a push-button
  • Bayonet-93 filter mount replaces the C lens's bayonet 104; front diameter down from 104 to 90 mm; 915 g against 1375 g (data sheet, cat. no. 10 48 78)
  • Aperture scale ends at f/22, where the C lens ran to f/32

Distagon CFE T* 4/40 FLE:

  • CFE after the focal length; four databus contacts on the bayonet plate for the 200-series meters; F setting retained
  • Same two-ring FLE focusing as the CF; bayonet-93 filter mount; 890 g; exact focal length 41 mm; 1:8.3 at 0.5 m (Zeiss data sheet, cat. no. 10 49 35)
  • Zeiss's sheet names 'digital chip backs' and 'NASA astronauts' among the users — the CF sheet names neither

Distagon CFE T* 4/40 IF:

  • IF engraved after the focal length; a single, wider focusing ring — the front FLE click-stop ring is gone (Zeiss data sheet)
  • 1130 g, heavier than the 890 g FLE lens; exact focal length 40.8 mm; diagonal field 87°; bayonet-93 filter mount; 1:8.3 at 0.5 m (data sheet, cat. no. 10 49 66)
  • Four databus contacts and the F setting, as on every CFE

Serial-range notes

red-ink code inside the rear mount, pre-1980
Zeiss stamped a date code inside the rear of every generation: before 1980 the last two digits are the month and the leading digit(s) plus 1957 the year, so 1005 = May 1967 and 1611 = November 1973. Lens serials are Zeiss's running numbers; no block-to-year table for the 40 was found.
red-ink code inside the rear mount, 1980 onward
From 1980 the code is two reversed year digits and a month letter, A = January — a CF FLE 40 reading 58F was made in June 1985.

ⓘ What these charts mean

MTF (modulation transfer function) shows how much contrast the lens keeps at a given fineness of detail, from the center of the frame to the corner — the coarse curves track punch, the fine ones resolving power, and a gap between solid and dashed lines means astigmatism. Relative illumination (falloff) shows how much darker the corners are than the center at each aperture. Manufacturers only began publishing these for modern lenses; no 1950s maker issued them, which is why older families here cite period magazine bench tests instead.

History

The 40mm f/4 Distagon arrived a decade after the 500C, in 1967 by the Zeiss and Hasselblad Historical chronology (Japanese Wikipedia says 1966), as the widest lens a reflex Hasselblad could take. Until then the only way to an 88° field was the Superwide’s fixed Biogon; Zeiss’s own data sheet for the C T* version makes the comparison, saying the Distagon “covers almost the same object field as the Biogon for the Hasselblad Superwide Camera” while keeping the mirror clearance a retrofocus design demands. The sheet (cat. no. 104163) gives 10 elements in 9 groups, an exact focal length of 40.9 mm, a diagonal field of 88°, an aperture scale to f/32, closest focus 0.5 m and a weight of about 1375 g — by far the heaviest lens in the C range — on a Compur size 0 shutter behind a bayonet-104 filter mount that no other V lens shared.

Two details of the C lens are worth knowing on the bench. The distance ring has a click stop at 0.9 m that must be pushed past to reach 0.5 m; the data sheet says the stop “is meant to remind the user that he must stop down at distances below 0.9 m”, since the lens is corrected for distance and has no close-range compensation. And the finish changed twice without the glass changing: chrome gave way to black around 1969/70 for the C line generally, and the red T* multicoating mark appeared from 1973/74 — the worldofdecay review gives the single-coated 40 as 1967–1973 and the T* as 1974–1982, without a month or serial for either.

The 1982 CF lens was a new computation, not a rebarrel. Zeiss’s sheet for it (cat. no. 10 48 78) says that against the “time-honoured” 40 the weight fell by one third to 915 g, the length by about 20% and the front from 104 to 90 mm, yet image quality “has been surpassed” because “an additional element has been introduced” — 11 elements in 10 groups — a step the sheet credits to T* coating making the extra glass-air surfaces harmless. The lens has two focusing rings: the rear one continuous from infinity to 0.5 m, the front one with three click stops (∞–2 m, 2–0.9 m, 0.9–0.5 m) that move elements 1 and 2 relative to the rest — the floating element, FLE, that “substantially improves image quality in the close range”. The filter mount shrank to bayonet 93 and the aperture scale now ended at f/22. Hasselblad Historical lists the lens as “Distagon f/4 40 mm CF (FLE)”; unlike the 50, there was no non-FLE CF 40.

The 1998 CFE (cat. no. 10 49 35) put the same 11/10 optics in the new barrel with four databus contacts for the 200-series meters, at 890 g; the 40 was made only as CFE, never CFi (Hasselblad Historical). Zeiss’s sheet for it adds that the lens was a “preferred lens in studios using digital chip backs” and that it “excels in aerial photography … at extremely high altitudes with NASA astronauts”. The third design followed in 2003, a date that rests on dealer and review chronologies rather than a dated Zeiss document: the CFE IF (cat. no. 10 49 66), 12 elements in 9 groups, 1130 g, with internal focusing and, per the sheet, “automatic optimisation of correction over the entire focusing range”, corner performance “significantly higher than predecessor at all apertures” and resolution “up to 200 lp/mm reachable”. The two-ring FLE arrangement disappeared into a single wider focusing ring. Production ended with the V system in 2013.

What remains open: who at Zeiss Oberkochen computed the 1967, 1982 and 2003 designs — no source consulted names anyone; the month of the 1967 launch and the chrome/black and T* boundaries for this focal length; any list price in any currency, since the 1973 and 1980 American dealer lists that price the 80mm Planar could not be read here for the 40; whether the CFE FLE and CFE IF overlapped in the catalogue; and every production figure, which would have to come from Nordin’s compendia.
