SHUTTER SPEED SETTING
Turn the shutter speed dial

to bring a selected shutter speed opposite to the
index mark

wedges to match the upper and lower parts of the split image. The best
sharpness is obtained when focusing is done at full aperture.
It should be noted that the focusing wedges and microprism collar, ensuring the
