Depth of Field Question

[wasabi8888]

Hi all

I asked a few people this and I got different answers.

Currently have a Nikon D80.

If I using a big aperture e.g. f4 and look at the subject (portrait) with a view finder, the background will look blur. If I then switch aperture to f11, will the image in the view finder be different after I press the shutter halfway? or do I need to press the depth of field button to see the increased depth of field?

When you change the aperture, when you semi-depress the shutter, the viewfinder will look exactly as it was when the aperture was fully opened. You have to press the depth of field button to see the increased depth of field.

Yes, that is correct. The camera keeps the lens at its widest aperture as that is the best for focusing, and not close the aperture to the setting you have set.

Yes, depth of field button is on the left side near the lens area. That is more accuarate..

To check for the depth of field(DOF) use the DOF preview button, located near your lens holding hand.

On the left side of the camera front are two unlabelled buttons, the bottom is depth of field preview, press and hold this button to stop the lens down to the selected aperture.

it can however get abit dark to see the effect taking place, so let ur eyes adjust a bit or get an eye cup for your viewfinder. i think the D80 already has an improved eye cup (dk 21) so says nikon.

another way would be to press the shutter fully and look at your nice big and bright LCD
you can also forward and backward the images to see the difference

yup, you need to press the DOF preview button to stop down the lens.

it will need a little getting used to but it is actually a very helpful feature.

More accurate? More accurate compare to what ?

Yes, you need to depress the DoF preview button. The aperture is stopped down only when this button is pressed or when the shutter is released. Half pressing doesn't close down the aperture.
