On page 36 of the Rebel XS (D1000) there is a section that says,
"Adusting the Viewfinder Clarity: Turn the dioptric adjustment knob left or right so that the seven AF points in the viewfinder look sharp."
I know where the knob is, however...
What exactly does this do? Does it change the way the camera focuses, or does it simply change the way things are seen through the viewfinder?
I thought the viewfinder showed exactly what the lens was seeing.
Are the little black boxes and dots only in the viewfinder? This would make sense since they obviously don't show up on the pictures.
Finally, HOW SHARP should the dots be? The little boxes in the viewfinder (seven on the XS) are very sharp, but the dots? Not so sharp.
Any advice on this is very much appreciated.
