Re: better living through electricity, or charge them babies

I bought a few new sets of 2100 mAH NiMH's a few months ago and they are 
already starting to run short, so I'm giving a set of lithiums a try.  I'll 
be interested to see how long the Lithiums last  and what their 
characteristics are when they fail.

A few weeks ago,  I noticed that the istDS AF did funny things in low 
light with my 85mm/f1.4.  Occasionally, the camera wouldn't fire, even 
though I thought it was in focus (on a manually selected zone).  It 
wouldn't even bother to hunt. A little while later, it would be fine. And 
then it would hunt on a perfectly brightly lit zone.  I thought this was 
because of the lens.

Tried it with the 77mm LTD tonight. Worked fine for most of a 1GB card, 
then started doing it on the second card.

D'oh. I think I know what it is. Once the batteries are partially 
depleted, and even though the rest of the camera fires fine, the AF seems 
to be a bit sensitive to the power levels. Of course after a while the 
batteries recover if I go for a while without shooting.

I'm using two sets of Sony 2300mAH NiMH's. I think I might buy a few more.
