According to NASA, the camera equipment on board was the following:
The onboard cameras for the
Apollo 8 mission were modified Hasselblad 500 EL cameras, with 80-millimeter and 250-millimeter Zeiss panacolor lenses.
For certain photographs of the lunar surface, a 60-millimeter lens with a reseau was used. Use of this lens and reseau is apparent in the views that show crosslike fiducial marks.
For analytical purposes, black-and-white emulsions were determined to provide a higher degree of resolution and image clarity than the color emulsions; therefore, much of the photography is black-and-white.
Approximately 90% of the photographic objectives of the mission were accomplished.
Approximately 60% of the additional lunar photographs requested as targets of opportunity were also taken despite early curtailment of crew photographic activities.
Many smaller lunar features, previously undiscovered, were photographed. These features are located principally on the farside of the Moon in areas that had been photographed only at much greater distances by automated spacecraft.
During the mission, seven 70-millimeter film magazines were exposed and yielded more than 150 photographs of the Earth and more than 700 photographs of the Moon.
Five 16-millimeter color magazines were also exposed.
The Blad used to shoot the Lunar surface shots from the Command Module was fixed, and ran on an interval timer, to automatically record images of the surface as they passed over it.
NASA/Hasselblad built a custom rig for this camera - below:
The output is available online these days - here's one Apollo 8 film magazine set:

Not really very inspiring to look at, but they captured a lot of new data, especially on the 'dark side' of the moon.
