A few weeks ago I encountered some of the odd *ist-D behaviour others have reported - batteries suddenly reporting 'no charge', but working just fine after switching the camera off & back on. Since then I've been doing a little more research, and this is what I've found out to date.
First, as has been mentioned before, it pretty much only seems to be a problem if you have batteries in both the camera and the grip; removing either set of batteries seems to eliminate the problem. Secondly, it appears to depend very much on the variation in state of charge of the batteries. If, as is my usual custom, I charge up all the batteries the night before I'm unlikely to have problems. Admittedly now I'm using 2500 mAh cells, and have switched from microdrives to solid state CF cards, it takes a lot of exposures before I put a noticeable drain on a set of batteries, although auto-focus can take a toll. But I do see the problem a lot more now than I used to; I'm forced to the conclusion that the 2500 mAh Energizers that I'm using now have a much faster internal discharge rate than the 1600 or 1800 mAh RayOVacs I was using last year. And that seems to be the big difference - with the RayOVacs I could pick up the camera after not using it for a month and expect there to be a usable amount of charge in the batteries. With the Energizers, though, going much beyond a couple of weeks seems to be inviting trouble. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
