Depth-of-field button
The LEICAFLEX SL 2 measures the exposure at full lens aperture. The depth-of- field button permits the assessment in the viewfinder of the depth of field to be expected with the pre-set stop-down. When the button (6) is pressed the lens diaphragm is closed to the preset value.
Please note:
During exposure measurement the button
(6) must not be pressed.
Depth-of-field scale
The depth-of-field scale indicates the range of the depth of field for the object distance set on the distance setting ring.
If, for instance, you have focused the 50mm SUMMICRON-R f/2. lens on 5m, the sharpness will extend from 3m to about 20m when the lens is stopped down to f/11. If you stop down only to f/4, however, sharpness will extend from 4m to about 8m. Detailed information about depth of field with all focal lengths is contained in our Depth-of-field Table No. 110-57.
