A Zeiss was used on Apollo 11. Were they all Zeiss?

...IIRC, they were Carl Zeiss lenses. The rule of thumb is if you can
afford them, go with Zeiss. Always.

That's what I thought, but I wasn't sure. I saw a picture of a 'blad
with a Kodak lens.

Given the total cost of the Apollo program, what makes me think that
NASA actually _could_ afford Carl Zeiss lenses? :-D

Too bad they couldn't afford a proper lens element of a hue/color
bandpass filter, as that would have eliminated their need of using a
xenon arc lamp spectrum of illumination in order to avoid the
secondary/recoil affects of raw solar UV giving things (especially
those 0.85 albedo white moonsuits) a black-light kind of bluish hue or
tint.
Too bad their polarized optical element wasn't working, as otherwise
that physically dark lunar surface would have recorded at roughly 50%
of the otherwise average 0.11~0.12 albedo, instead of looking exactly
like a certain terrestrial guano island of 0.65 or greater that had
been modified to look similar to lunar background terrain.
Many of their images seem to have fuzzy transitions between their
foreground and of that guano island background looking so eroded
smooth, with few if any surface meteorite or secondary impact shards.
It seems Mars looks more moon like than our moon, and Mars is even
looking a whole lot physically darker than our moon, as well as
covered with a good many meteorites and secondary impact shards.

Zeiss Sonnar f-5.6/250 mm telephoto lens was also carried.
For Apollo 11, two of the 500EL's were identical to the ones carried on the
Apollo-8, -9 and -10 flights
One of the conventional 500ELs, along with the telephoto lens and two extra
magazines, was in the Apollo-11 Command Module throughout the flight. The
other conventional 500EL, and two extra magazines as well, were placed in
the lunar module.
Also in the lunar module - and making its first journey in space - was a
Hasselblad 500EL Data Camera, which was the one to be used on the moon's
surface.
(1) The Data Camera was fitted with a so-called Reseau plate. The Reseau
plate was made of glass and was fitted to the back of the camera body,
extremely close to the film plane.
(2) The Data Camera was fitted with a new Zeiss lens, a Biogon f-5.6/60 mm,
specially designed for NASA, which later became available commercially.
Careful calibration tests were performed with the lens fitted in the camera
in order to ensure high-quality, low-distortion images. Furthermore, the
lens of the camera was fitted with a polarizing filter which could easily be
detached.
(3) The Data Camera was also given a silver finish to make it more resistant
to thermal variations that ranged from full Sun to full shadow helping
maintain a more uniform internal temperature. One of these was presented to
Her majesty Queen Elizabeth as a memento of the space program. Buzz Aldrin
was on hand at the time to explain to the queen about the camera's.
The two magazines carried along with the Data Camera also had silver
finishes. Each was fitted with a tether ring so that a cord could be
attached when the Lunar Module Pilot lowered the mated magazine and camera
from the lunar module to the Commander standing on the lunar surface. The
exposed magazines were hoisted the same way.

Wow! Thanks for all of that detailed information.

Do you know the age of the camera? (The Hasie's since 1960s had CZ
lenses, but earlier Blad's did come from the factory with Kodak lenses.)

It was an early one:
