If the lens is big enough, the delay becomes trivial. I don't notice a 1/10" 
delay, myself, and almost all my daytime shots are faster than that. YMMV.

It certainly takes longer to focus than to get the image from the lens to 
the LCD. :-)

As far as I know, yes.

Well, no, it's because the D90 doesn't have an infrared filter that drops 
down over the lens when you say "use infrared." :-)

If you had an optical filter and you're trying to line things up with 
infrared, you *eye* would have to be seeing the infrared.

Sure.  I was just discussing some of the benefits of LCD viewfinder over 
optical viewfinder.

Indeed.

Sure they have. That's exactly what I'm talking about hte Sony F707 doing, 
aren't I?  That's basically just what the Sony does, except it has an LCD in 
the back and another behind the viewfinder.
