My camera has a D.O.F. Preview button. Can't understand what it does or how it does what it is supposed to do . Please any advice would be appricated.

It's to let you know before you take the picture how much of the pic is going to be in focus. I can only explain from what I have read in my NYIP course. I know others here can give you more info.

When you push the button, it stops the lens down to the selected aperture & that allows you to see how much of the scene is in focus...It gets a little hard to see thru the viewfinder with smaller apertures as the amount of light the lens lets in decreases as the aperture get smaller

It is one of the most important buttons on the camera. It tells you what is in focus and what is not.
Set you camera at say f11 and focus on something, then push the button and you will see all that is in focus and all that is not.

D.O.F. stands for Depth of field. That is the area in your photo that everything is in focus. Normally when you are viewing and composing your photo the lens is at its maximum aperture which show you the minimum DOF. To see what the Actual DOF will be when you take the photo and the aperture closes down to the meter setting you actuate the Preview button and you can see the DOF you will have. In reality, when you do this it may be hard to tell because the view screen may be to dark to tell. Good luck.

The view screen may be too dark but with a dslr the viewfinder will get dark but one would be able to see what one is shooting.

It would still be hard even with the brighter viewfinders on top end DSLR's. I know years ago it was difficult ascertaining the DOF when I had that feature on an old Minolta SRT 101 as the screen was so dark with F8 or smaller. Even in bright daylight. With limited light situations, it was impossible.

Very handy button. I used it often in film. Now I shoot primarily with a Nikon D5100. For that I use Live View for DOF.
