I always thought Contax had the coolest names for their cameras at one time.
With Minolta always tripping over themselves trying to put the number 7 into their nomenclature (XE-7, XG-7, X-700, X-7a, 7000, 7000i, 700si etc. etc), and everyone else trying for some techie combination of letter and numbers, I rather admired Contax for their classy sounding 137MA, 139, 159, 167 - then they had the Aria, which sounded just like some German company would name their mid-1950's rangefinder or something.
I do agree with the above posters that there's something lacking in today's model designations. I mean, how long a product marketing meeting was needed at Canon for them to decide to follow Nikon's D1 with their 1D? Sheesh?
Then again, Japanese companies don't always get it right, do they (and Pentax, we're looking at you). It must have seemed like a great idea to badge Pentaxes with *ist, after Canon had such success with their EOS. Bad, bad, idea guys. And yet, somehow, a large corporation was talked into thinking it was a great name for the ages to come.
I suppose it's preferable to keep present model names alive, and just keep tacking "II, III, IV" onto them, or adding letters here and there. Could we end up with a K-1v, or something like that someday? Better that than *ist
