  1. Element and group counts, weights, closest focus, exact focal lengths and filter series are from the Zeiss data sheets hosted by Hasselblad Historical (C50, CF50FLE, CFi50, ZV50). No sheet for the non-FLE CF 50 was found.
  2. Generation start years follow the barrel/shutter families (CF 1982, CFi 1998, ZV 2006); the 1964 launch and the 1989 FLE date come from review and dealer chronologies, and the black and T* changeovers are undated for the 50 specifically.
How to tell them apart (expand)
  • Two optical designs under one name: 7 elements in 7 groups from 1964 through the first CF (to 1989); 9 in 8 with a floating front group in the CF FLE, CFi and ZV
  • A front click-stop ring with four distance ranges means FLE; a single focusing ring means the older 7/7 lens, whether C or CF
  • Filter mount sorts C from later: bayonet 63 on every C lens; bayonet 60 on CF, CF FLE and CFi per dealer descriptions (the Zeiss sheets print 93 and 70 — unconfirmed); 67 mm thread with a 60-series bayonet on the ZV
  • Red T* on the name ring from 1973; chrome barrels are always pre-T*
  • Only the CF, CF FLE and CFi have the green F setting for open-shutter use on a 2000/200-series body; the 50/2.8 F and FE are a different lens

Distagon C 4/50, chrome (1964 baseline):

  • Satin-chrome barrel, engraved Carl Zeiss / Distagon 1:4 f=50mm; 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-63 filter mount (Zeiss data sheet: 'adapter ring for Hasselblad series 63'); 0.5 m closest focus; about 885 g
  • 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 4/50, black (non-T*):

  • Black-anodised barrel with the same C-type engraving, EV lever and bayonet-63 mount as the chrome lens; no red T*
  • Same 7/7 optics and 885 g as the chrome lens — finish only

Distagon C T* 4/50:

  • Red T* after the Distagon name; black barrel; bayonet-63 filter mount; EV interlock lever
  • Zeiss data sheet: cat. no. 104148, 7 elements in 7 groups, 885 g, 0.5 m, Compur size 0 with automatic diaphragm

Distagon CF T* 4/50 (non-FLE):

  • Single focusing ring — no front click-stop ring — on a Prontor CF barrel with rubber grip, green F on the speed ring and push-button EV interlock
  • Bayonet-60 filter mount, as dealers describe every CF and CFi 50 (KEH)
  • Hasselblad Historical lists it separately from the 'CF (FLE)' lens; no Zeiss data sheet for this version was found

Distagon CF T* 4/50 FLE:

  • Two focusing rings: a front ring with four click-stopped ranges (∞–4 m, 4–1.2 m, 1.2–0.8 m, 0.8–0.5 m) that shifts elements 1–4, and the usual rear ring ∞–0.5 m (Zeiss data sheet)
  • FLE engraved on the barrel; aperture scale now to f/32 where the C and non-FLE CF stop at f/22
  • Exact focal length 52 mm; about 800 g; reproduction to 1:6.3 (data sheet, cat. no. 10 49 08)
  • Filter mount: the Zeiss sheet prints 'bayonet for Hasselblad series 93', but dealers (KEH) and the ZV sheet's 60-series outer bayonet point to bayonet 60 — treat the sheet's 93 as unconfirmed

Distagon CFi T* 4/50 FLE:

  • CFi after the focal length; no databus contacts — the 50 was made as CFi, not CFE (Hasselblad Historical)
  • Same two-ring FLE focusing; 9 elements in 8 groups; exact focal length 51.9 mm; 800 g; 1:6.3 at 0.5 m; f/4–32 (Zeiss data sheet, cat. no. 10 49 49)
  • Filter mount: the sheet text reads 'series 70', which matches no dealer description (bayonet 60) and is carried here as a sheet-reading to be checked

Distagon T* 4/50 ZV Classic (Zeiss-branded, 2006):

  • Sold by Zeiss under its own name, not Hasselblad's — ZV after the focal length; 67 mm filter thread plus a 60-series outer bayonet (Zeiss data sheet)
  • Half-stop aperture clicks, f/4–32; 790 g; ø 80 mm × 92.3 mm; same 9/8 FLE optics and 0.5 m / 1:6.3 as the CFi

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 705 = May 1964 and 1611 = November 1973. Lens serials are Zeiss's running numbers; no block-to-year table for the 50 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 — so a CF 50 reading 98B was made in February 1989, and a lens with an FLE front ring should read 98x or later.

ⓘ 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 50mm f/4 Distagon was the Hasselblad V system’s everyday wide-angle from the mid-1960s to the end of the line, and for most of that time the lens behind the name was one of two quite different designs. The launch year itself is unsettled: Christian Schroeder’s 35mmc review and most dealer chronologies say 1964, some lists say 1965, and Japanese Wikipedia’s product list gives 1963. Zeiss’s data sheet for the C T* version (cat. no. 104148) describes the first design — 7 elements in 7 groups, no cemented surfaces, exact focal length 51.3 mm, diagonal field 75°, f/4 to f/22, closest focus 0.5 m, about 885 g, a Compur size 0 shutter and a filter adapter for Hasselblad’s series 63. The sheet is candid about the design’s limit: the lens “is corrected for large object distances” and “should be stopped down further when it is used for close-range work”.

The barrel followed the C line’s changes without the optics moving. Chrome gave way to black around 1969/70 — Schroeder’s own lens is a black, non-T* example from 1970 — and the red T* multicoating mark arrived in 1973. In 1982 the same 7/7 glass went into Prontor’s CF shutter with a rubber focusing grip, a push-button EV interlock and the green F setting for open-shutter use on the 2000-series bodies. Hasselblad Historical’s lens index lists this “Distagon f/4 50 mm CF” as its own row, separate from the FLE lens that followed; no Zeiss data sheet for the non-FLE CF was found, so its weight is not given here.

The second design is the 1989 FLE. Zeiss’s sheet (cat. no. 10 49 08) gives 9 elements in 8 groups, exact focal length 52 mm, an aperture scale extended to f/32, and about 800 g — lighter than the C despite “the addition of further lens elements”. Like the 40mm CF FLE of 1982 it has two focusing rings, but with four ranges rather than three: the front ring clicks between ∞–4 m, 4–1.2 m, 1.2–0.8 m and 0.8–0.5 m and moves elements 1–4 relative to the rest, after which the rear ring focuses normally. The sheet says distance performance stayed very good and the floating element “has given a considerable improvement in the near range”. Schroeder calls the FLE “a totally different beast” that “commands prices that are way higher” than the older lens.

From 1998 the FLE optics were sold as the CFi (cat. no. 10 49 49) — improved shutter mechanics and grip, no databus contacts, since the 50 was made as CFi rather than CFE — and in 2006 Zeiss reissued them under its own name as the Distagon T* 4/50 ZV Classic, with a 67 mm filter thread inside a 60-series bayonet and half-stop aperture clicks (Zeiss ZV sheet; Hasselblad Historical lists three ZV lenses). One detail the data sheets leave untidy is the filter mount: the CF FLE sheet text reads “series 93” and the CFi sheet “series 70”, while dealers describe every CF and CFi 50 as bayonet 60 and the ZV sheet confirms a 60-series outer bayonet. The sheet figures are carried here as read, flagged rather than corrected.

What remains open: the launch year (1963, 1964 or 1965) and who at Zeiss Oberkochen computed either design — no source consulted names a designer; the chrome/black and T* boundaries for this focal length; a list price in any currency; the filter-series discrepancy above; when the ZV Classic left the market; and every production figure, which would have to come from Nordin’s compendia.
