Re: OT: autofocus

Oliver,
 
I always enjoyed my Nikon N90s, 35-70/2,8 and 70-200/2,8 as a family photo kit. 
If you want more frames per second, faster AF and better metering and a pro 
body, go with the Nikon F5. It's a real handful, but built like a tank.
You should be able to get it all used in very nice condition for a fraction of 
new costs.

Subject: OT: autofocus


I appreciate the many replies to my question. Allow me to respond. 
On a typical bright day, my basic exposure for ISO 100 is f/8 at 1/250 or
f/4 at 1/1000 for a candid whose subject holds still. 
IMO pre-focusing on an chosen distance and depth of focus is OK for
photographing an object whose trajectory is reasonably predictable. Rugrats
aka anklebiters exhibit Brownian motion.
IMO using a wide angle lens will likely result in the object of interest
occupying a small fraction of the frame, thus necessitating considerable
enlargement with attendant degradation of the image. 
IMO too much depth of focus will cause distracting background to be too
sharp to be ignored by the viewer.
I am biased in favor of optical viewfinders and manual controls. I am not
prepared to squint at an iPod screen in bright sunlight while manipulating
an array of buttons that are smaller than those on my cellular telephone.
I will visit a few local camera stores (we only have a few) to handle the
suggested AF film cameras. How significant is AF speed for a prime 50mm or a
modest zoom (35-75 or so)?
Thanks again, and keep those comments coming! 
Oliver
