I would go for a comma too. Let me try to explain (poorly though it may be; I think I'm missing some key grammatical terms). "The *comparative*, the *comparative*" is a quite acceptable English idiom, despite lacking any verbs, but only when it stands alone. It's a unitary construct, isolated from the grammatical flow of the sentence around it. The use of "that" breaks this isolation; it no longer reads correctly because it now sounds like it needs a verb or two: "...principle is that the greater the distance *is*, the greater the depth of field *is*." A colon seems like too sharp a separation to me, so that's why I'd support a comma: "...principle is, the greater the distance between lens and subject, the greater the depth of field." I have no opinion on the second point as I don't recognise "Student's" and don't know how it's classified here. -- Tim Pederick
