Emily,
The only benefit it could have is that it saves you from having to
crop a full frame 35 mm image to achieve the same result you would
have with the digital image. (If that small step is a benefit.) I
wasn't speaking of "mechanical length," which depends on specific
optical design issues. My only position is that the 1.6 multiplier
effect is not a benefit. It doesn't convert a 50 mm lens into an 80
mm lens.

Emily,
I suggest you go back and read the posts. I've erased them now,
but I distinctly recall some folks talking about the 1.6
multiplier as a benefit.
Yup. Probably me. It definitely is a benefit to me, as I said.
But I don't confuse it with the actual mechanical length of the
lens I'm using.
