Hasselblad, the First Camera Worn on the Moon

NASA astronauts often posed with Hasselblad cameras, be it for individual portraits or official crew photos.
Two examples;
1967 official individual portrait of astronaut Karl Henize

.
1968 official Apollo 7 crew photo, a photo series during which Walter Schirra was wearing a Rolex Daytona 6240 on riveted bracelet

Man! Once Ive grown my mullet, I certainly want to neaten it up with a table-top like that! 🥰

As the question was asked about Hasselblad vs Leica (or something else)... we'll have to say " something else "
😗
As a contract was signed between NASA & Hasselblad, we see three other makes of cameras onboard Gemini & early Apollo missions:
Nikon ... RCA - Radio Corp America (hand-held TV cameras) and Maurer ( DAC - Data Acquisition Camera )

.
Here's an October 21, 1966 photo showing Gemini XII pilot Edwin Buzz Aldrin installing a Maurer 70 mm DAC still camera in the capsule.
The Maurer could be used with three types of lenses; standard, low-light and ultra-violet.

At 3:07 he meant " Mercury " missions... not Gemini
