What comes after the K-7? Well, features aside, the name will be impossible to predict. It's nice that the K10D was logically followed by the K20D, which means the K-7
should have been the K30D or K-30. Therefore, the K-7 follow-up will probably be named something totally arbitrary like the "K15" or the "K-14x" or the "K22-mx" or the "K-35mxd".
Now that the K-7 exists, Pentax has also screwed up their chance for a logical name of their first FF SLR (if one is released) since
that should have been called the K-1 or K1D. I suspect it will be called the K326Q, for no particular reason.
Anyway, I've been musing lately about just how some manufacturers come up with their unusual camera names, so I thought I'd make fun of Pentax about this to get it off my chest.
