The cameras on the moon were mostly wide-angle lenses. Everything looked far away.
They had no proper viewfinder, as viewfinders of the era relied on bringing the camera up to your eye, which is obviously impossible when wearing a helmet which keeps the camera several inches away from your eye.
This means that if you want to have something in shot, and also be handheld, it pretty much needs to be a wide-angle lens, or you’re going to miss a _lot_ of photos.
