D100: Trap Focus Trick
Here are some tips:
http://www.nikonians.org/cgi-bin/dcforum/d...rum=DCForumID62
to paraphrase for the D100:set CSM menu item 14 (AE-L/AF-L) to "AF-ON"
front focus selector to S
focus using the AE-L/AF-L button on something the same distance as your expected subject
back off or point in alternate direction
point in the direction of your expected subject
hold down (lock with a cable release or finger ) the shutter
It looks like these tips are for Autofocus. This is the technique that I wrote up last September after getting my midwater squid photos with the 105.
I'll try them in Manual focus this evening w/ the D100 and see what happens.
Cheers
