Yes, the D5s are the 'official' Handheld Universal Lunar Cameras (HULCs), but (a?) Z9 also got on-board at the 'last minute' (which means two years ago):

They have a thermal blanket for exterior work:

The D5 has been used on the ISS, including EVAs, since 2017, so they're a known quantity:

The Mercury and Apollo missions used Hasselblad 500-series-based cameras (modified):

as a Hassie lover it made me a bit sad that they went with a D5 but hey, who cares about the camera, the picture was worth a billion bucks and it delivered.
It's so refreshing to be mesmorised by a picture in the age of shorts and reels.
the morning after the launch i just randomly went onto their livestream and one of the astronauts was asking mission control for help on also using the gopros and iPhone cameras. i guess they have some. and he was struggling at getting a properly exposed photo with those. he said they were coming out super over exposed. but the D5 was working nominally. mission control said they'd get back to them about ideas on adjusting the gopros and iPhones. but it was funny to hear they're trying "new" tech and struggling with it up in space, and that 2005 D5 is still the champ :)
