Yep, hence the suggestion to improve DSLRs with an EVF switch. The
advantages of EVF don't require high res if you can flip freely
between
optical and digital. In some ways the digital preview is more useful
at
very low resolutions, like for example light meters, and more
specifically the idea of getting a realistic squint reality check on
your composition and exposure. It probably doesn't take many pixels to
build a reliable live histogram. That's what you want in the
viewfinder
when twisting the aperture ring, or maybe DOF preview, depending on
the
situation.

With many DSLRs now having Live View you almost have that.


"Almost" is optimistic. There isn't yet a Live View screen, nor an
electronic viewfinder (EVF) that adequately displays depth of field.

To be fair, few if any optical reflex viewfinders will display DOF
unless you change the focusing screen. The aftermarket focusing
screens designed for manual focusing do a far better job of displaying
the fall-off of focusing sharpness, but they still aren't perfect.

Still, my Nikon D700 with Katz Eye screen does a far better job than
any Live View screen or EVF can.

Bruce, agreed, but Paul was suggesting the EVF/LCD for "very low
resolutions". With today's DSLRs you have both the Live View for that,
and the optical when you prefer that (as I do ~98% of the time).

DoF preview, as you say, is not often offered, and unless you change the
screen, may not be very accurate.
