D100 Question

With my D100, I generally use single servo autofocus (S). I usually get good results with "S" both underwater and topside. The D100 manual lists a number of autofocus options. One of these is AF-Area Mode (p. 65 in the English manual). Does anyone have any experience with the dynamic-area AF, and if so, does it have much application for U/W? Also, for dynamic-area AF, there is an option called Closest Subject Priority.

I'm clueless! Thanks for any information.

RE closest subject priority: most people turn it off. It slows the focus way down.

RE dynamic-area AF mode - use it if you don't mind the camera choosing what it focuses on. :-)

AF-area allows you to tell the camera which focus point to use. That's what I do. Center on subject area you want in focus, half press shutter or hit AF-lock, then recompose.

S-servo is good if you want the camera to get a focus lock before it fires. It's annoying if the camera can't get a focus lock though - no shot for you!

Continuous will fire off a shot anytime the button is fully pressed. This is good if you have a big DOF for shooting fast moving WA subjects.

That's my 2cents

Cheers,

James

Also useful for moving subjects (i.e. sea lions, sharks) is autofocus with focus tracking - set to C and choose dynamic. Once the camera is focused on a subject it will continue to try and track that subject as it moves. This is also excellent for sports photography topside.

For smaller subjects, it can drive you insane

I think the jury is in. I'll keep shooting in "S" with no options.

I really appreciate the information!
