17: Magnified View enables you to zoom the image right after you shoot it. I
have no idea why this requires a menu option, even my canon point-and-
shoots do this, automatically.
0: Playback only. You have to hit the Play button before you can zoom
in. Stupid.
1: Review and Playback. You can zoom in after hitting the Play button
as before. Also, while the image is reviewing, you can hold the
squiggle/printer button while pressing the (+) (magnify) button to zoom
in. This lets you magnify the image without having to hit Play. Beats me
why you have to enable this in a custom function; all the Canon point-
and-shoots do this by pressing their SET buttons without needing any
menus.
18: Lens AF Stop Button lets you select what happens when you press AF
Stop buttons which appear only on Canon's super telephoto lenses. Most
lenses don't have these buttons.
19: Add Original Decision Data adds a checksum to the image file. If you
pay $700 extra for the DVK-E2 software kit, when playing back images you
can get your computer to tell you if your file is as it came from the camera, or
if it's been altered. This is something Canon pitches to people who use photos
for evidence and forensics. I have no idea if anyone believes any of this. I
wouldn't.
