Yes, sir, they are indeed digital but I only included them from a quick search. As for the Nikons, you will find that F3, FM2 and FM2n are all magnesium alloy. Zeiss too uses magnesium and this is not digital, I guess. I don't disagree with you that probably some use alumium, but there are some books on cameras that confuse magnesium-aluminium alloy for an aluminium alloy. It is mainly magnesium with aluminium added to it in small quantities not the other way round.
I am afraid I will have to leave it here because an additional post with a few more brands was blocked for some reason or another. Perhaps because I gave an example of brands that are not approved of.
I don't think I will be posting anything else in the near future. I will return to being just a reader as I have been in the past.
