Enough a reason could probably be not enough power/duration.

Anyone using the Alcava (or any other brand, if available) rechargeabe alkaline batteries on the D/Ds?
They are 1.5V instead of 1.2V, and they should probably fix such recurring problems I see reported here. I used them on my MZ-S, with great satisfaction. I've never tried them with the D, only because I've never had "low voltage" problems with Ni-MH (so far).
Any known reason for not using them?
All the best,
Dario

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.
