  1. Wides aperture at it's longest focal length (F= 5.6 shutter speed= 1/500 Focal length = 140mm)

  2. Narrowest aperture at it's shortest focal length (F=22 shutter speed=1/125 Focal length = 18mm)
  3. Fast/quick shutter (F= 4.2 shutter speed=1/800 )
  4. Slow shutter (F=4 shutter speed=1s )
  5. Image too dark (F=22 shutter speed=1/125 )
  6. Correcting the light meter(F=22 shutter speed=1/25 )
