I hadn't caught the irony in my intentionally spelling it "you-all" while at the same time asking about correct pronouncation. I don't even use the phrase very often, but when I write it I like using the older, maybe even archaic, spelling "you-all". It's actually just spelling out the contraction "y'all" or "ya'll" (let's not get into the debate over how to properly spell the contraction), and not using a contraction is always proper. It's all for fun anyway; I'm not even from the US South...
Back on topic, I figured the "six-by-seven" pronouncation was most common. Does anyone have something "official" that shows how Pentax intended it to be called? Not that it really matters, I'm just interested.
