The view screen's image is a little smaller than a typical 35mm.
It is magnified but not by 1.6X (maybe something like 1.4x)
The view screen is not as bright as a good 35mm view screen and
this makes focusing more difficult.
The bottom line is that most people will not be able to tell really
critical focus with the D60's viewscreen. This will be
particularly an issue with short DoFs.
The LCD on the back is also useless, even in the "zoom mode" to
tell critical focus. Many a person has shot a bunch of shots in
MF thinking they were doing great only to get home and find out
that everything was a little out of focus.
It's pretty hard to believe that
'everything was a little out of focus': normally the wrong thing is in
focus on a macro shot when I make a mistake. Or are we
talking about people who only shoot lens charts here?
I do pretty well
in macro work, indeed close to 100% when I am using a tripod
and have a static subject (not a flower waving in the wind or
a butterfly flapping its wings). Hand-holding with a moving subject I
get over 50% right. And as I took over 1000 images in the last month
of flowers and butterflies, those are real numbers (and you might
like to check my profession)
There has been some success reported with the angle viewfinder that
has magnification in it.
I own one, and it can help, but I do no better with it than without it.
As you have to refocus it to change magnification, this is only feasible
on a tripod with lots of time. And you also magnify the 'grain'
of the focussing screen.
Is the smaller viewfinder on the D60 a problem with manual focusing?
I did expect it to be a problem. It is not as bright as a good 35mm
viewfinder, but the 'laser matte' screen of the D60 is as good as
any I have used. I do no worse than I did with my Minolta film
SLRs, including topline models from the era of MF lenses.
