Just a little spoiler
from a critical tester:
Reviewing dof depends
extremely on magnification
. That is the final
magnification of the image that you're judging
On a 3" monitor at 25cm viewing distance this is 7x smaller
than on your 21"-monitor or a A3-print - and dof shrinks with the square of magnification!
When you look through the viewfinder of an APS-C cam you have a total magnification of around 0.9x which is near life-sized.
So I bet you can judge dof at least as good through the view-finder as on live-view...
: Just made a test, looking through my D80 with the 50mm/f1.4 mounted down the line of a ruler focussing on 0cm. 3cm was obviously blurry, 4cm was hard to read. Than I looked through my olde Olympus OM2n with an excellent and certainly not too transparent viefinder with the 50mm/f1.8 mounted. In this case the 4cm was more readable than with my Nikon combo - in line with expectation from the smaller aperture.
And testing the magnification by looking through both viewfinders simultaneously (!) I can confirm
that both deliver the same magnification
, the Oly having the wider fov (naturally). So I am really comparing apples to apples.
This confirms that the rant about DSLR-viewfinders beeing cheating on dof certainly does not apply to the Nikon viewfinder or
has been all the same with the classical film-viewfinders (and the Oly OM2n had an excellent one).
All in all dof-preview on live-view is a bit overrated in my opinion.
