Regarding depth of field.

When the photo comes out, does it have shadower DOF than
what we see on the viewfinder?

I think most of the time I use F/8, but the max aperture of the
lens is F/4~5.6, thus I expect more DOF in the photo than what
I see in the viewfinder.

Press the DOF preview button.

Believe in what you see yourself...

u may expect more, but the difference may not be significant.... dof depends on various factors....

focal length
distance from lens to subject
distance from subject to other elements in the image
aperture

so while u may change aperture, it may not be significant enough to overcome the other factors which are creating a shallow dop....

And also, how big is your print size. It is related to CoC (Circle of Confusion) of the sensor/film size.

Is there such a button, or is it only on certain cameras??

Most nikon and canon DSLRs have it..

Pretty useful feature. When set to F22, and depressed u can see it darken but the DOF really increased(thru viewfinder)..

If you view through a viewfinder, given the size of the image that you see in the viewfinder, I think you may see a greater depth of view than the actual picture. Furthermore, since the image darkening when the DOF button is depressed, to me, it affects judgement as well. Even though the frame looks generally clearer, but the most accurate gauge is the the picture after it is taken.

Not all camera have it. I know D50 don't have it. D70/D70s have it.
