 Shutter Speed and Aperture Shutter Speed and Aperture
Because the camera uses a lens-internal shutter, fast shutter speeds may not be available at large 
apertures.  If the selected combination of shutter speed and aperture is unavailable, shutter speed or 
aperture will be displayed in red and the desired exposure may not be achieved.

 Sensitivity Sensitivity
“Sensitivity” refers to the camera’s sensitivity to light.  Choose from values between 200 and 6400, or 
select L (100),  H (12800), or H (25600) for special situations.  Higher values can be used to reduce 
blur when lighting is poor, while lower values allow slower shutter speeds or wider apertures in bright 
light; note, however, that mottling may appear in pictures taken at high sensitivities, particularly at 
H (25600), while choosing L (100) reduces dynamic range....
