Originally posted by WMBP When I bought the K10D, upgrading from a K100D, I wasn't initially happy about moving to a proprietary battery. I had been using cameras for years that ran on AA batteries and was convinced a proprietary battery was a dumb idea.
I was wrong. The battery for the K10D/K20D carries so much charge that I've only once in the last few years had to change batteries in the camera in the middle of a shoot. That happened just recently and I'm almost certain that it was because I got confused the night before and failed to properly charge up the battery that I put in the camera at the start of the day.
I wish that I could use proprietary batteries in my flash units that held a charge as long as the camera. I do have a battery pack (takes 6 C batteries) for my couple Pentax 540 FGZ units and it's worked well, but now I use the Metz 58 more and I don't have a pack for that. Eneloops are great but I do have to change batteries in the middle of a shoot pretty often.
I guess the K7 may have the best of both worlds: proprietary battery in the body with the possibility of using AA batteries in the grip. Does anybody know if the grip will also take the proprietary battery? Or do you have to use AA in the grip?

Having bought a K10D, a couple years ago, I'd never switch back to AA's. The rechargeable AA's don't match up at all. Not even close.
lithium Ion batteries *require* circuitry that stop drawing power before the battery loses charge to avoid destroying the battery's integrity.
People want to complain, they should complaint that most (if not every) AA device lacks this circuitry.
Here's what I want to know. Does the K7 on rechargeable lithium Ion AA have the correct circuitry to avoid damaging the batteries?
