Clarification: If you alter exposure using Flexible Program, the manner in which you varied the exposure is retained until Flexible Program is cancelled. For example, if the camera suggested f/4 at 1/125 and you rotated the rear command dial to select f/2.8 at 1/250, the camera will now alter its program to use shutter speeds that are one stop faster (or apertures one stop faster, you can think of it either way). If you had altered the program to provide f/5.6 at 1/60, then the camera will use shutter speeds one stop slower (or apertures one stop slower) until you cancel Flexible Program.
The current edition of the book incorrectly identifies the two buttons to press to reset the camera on page 32. The second button should be the Mode button, not the +/- button.
Page 102-103: I'm incorrect about the legacy issue. I must have been hallucinating when I wrote that as the F5 doesn't have a command dial on the vertical release. Also, I'm informed that at least one user has an F100/MB-15 combo that doesn't work as described in the Note for that Custom Setting.
Page 131: The Available Flash Features chart is incorrect for the Red Eye Reduction feature. Only the SB-80DX, SB-50DX, SB-28/28DX, SB-27, and SB-26 currently support that feature with the F100.
