It is my opinion it would be nice if we could keep it that way, for the sake of continuity, and of clarity.

I couldn’t care less about whether a historical perspective entailed either a deep or a shallow DOF for good DOF, personally to me, a good DOF isn’t defined on such “fixed” terms, rather, how it renders for a situation. It could be shallow, it could be deep, or somewhere in between.

Which doesn't clarify a darn thing, does it? Useless.

Clarify what?

Clarify what is MEANT, that's what!

Think about it.

If a poster comments that he wants a camera capable of "good DoF"...

-(which is something that now happens quite often)-

... are we supposed to understand he means SHALLOW DoF...[??]

-(which, these days, is very often what he DOES mean, in that he requires blurred backgrounds and has heard that this is a Depth of Field effect)-

....or are we supposed to understand "good DoF" as meaning DEEP  DoF, which is my position, is the traditional position, and is logical since it is DEPTH of field we are TALKING about!

Or are we supposed to take YOUR position, which is to understand nothing whatsoever by it, thus rendering the term useless to anybody.
Clear enough for you, now?

No, you don't have to take my position or expect anybody to get along with yours, or what others have believed historically or today. I'm more interested in discussing good DOF and presented my opinion on the subject.

What is good DOF? As I said earlier, and something that got on your nerves... a good DOF depends on the situation. Deep DOF, as you assume to be, is NOT a guarantee of good DOF for all situations. Likewise, Erik (had an exchange with him on the same issue) assumes the shallower the better. That is another extreme approach.

I will not accuse you of pretending to be stupid, but I do think you are being deliberately obtuse...

Well, obviously you can't think. If you could, you would actually engage in a discussion on the point being made.
