Acceptable focusing
Slight vignetting or moire phenomenon affects screen image, but film image shows no traces of this.
Blank box means not applicable. Since type M screen can be used for both macrophotography at a 1:1
magnification ratio and for photomicrography, it has different applications than other screens.
For the K2, B2 and E2 focusing screens, refer to the columns on the K, B and E screens, respectively. For
details, also refer to the specific camera's instruction manual.
MINIMUM APERTURE LOCK
must A
For programmed auto or shutter-priority auto shooting, use the minimum aperture lock lever to lock the lens
aperture at f/22.
1. Set the lens to its minimum aperture (f/22).
2. Slide lock lever in the direction of the aperture ring and so the white dot on the lever aligns with the
orange dot. (See illust.)
To release the lock, slide the lever in reverse direction.
DEPTH OF FIELD
Depth of field can be checked with the white indicator engraved on the lens barrel.
If your camera has a depth-of-field preview function, it is possible to check the depth of field in the
viewfinder. (For details, see camera instruction manual.)
Depth of field can also be checked by referring to the table on page 38.
