Checking Depth of Field

There are two ways to check depth of field. One is by using the depth-of-field scale on the lens. This is a scale of f/stops repeated on each side of the distance index.
1. First focus. Then press the shutter button halfway and note to which f/stop the meter needle points in the viewfinder. Find the two f/stops on the depth-of-field scale which correspond to that number.
2. Draw imaginary lines from those two numbers to the distance scale. The effective depth of field lies between those two distances.

You can check depth of field visually in the following way:
1. Focus the subject. Then press the shutter button halfway and note to~hich f/stop the meter needle points in the viewfinder.
2. Turn the lens' aperture ring to that f/stop.
3. Push in and then release the stop-down slide so that it unlocks and you can see its red line. Now, just by look~ng at your subject through the viewfinder, you can see the range of sharp focus.
4. After checking depth of field, push in and then release the stop-down slide.


Note

It is impossible to release the stop-down slide when the lens' aperture ring is on "A." If you are using the camera in shutter-priority AK, first disengage the lens from "A" and set the working aperture. After checking depth of field, return the aperture ring to the "A" mark.
