Will CRV3 batteries work?
I don't see why not as long as the OAL is the same ?

Pentaxians, help me out with this. So on the K10D/K20D you put 1 battery in the camera and 1 in the grip, right? What happens if they run out? Do you have to remove the grip to replace the one in the camera?

Canon grips have a stalk that go into the battery cavity in the camera, so no battery goes in the body with a grip attached. Rather, you put 2 batteries in the grip.

On the K10/20 you'll have to remove the grip to swap the battery in the body. But you can also set the camera to use the battery in the grip first, that way you don't have to swap that all the time and just use it as a spare one. After all you'll shoot quite a few images on just one battery.

It should be possible to have three batteries. Two in the grip and one in the body. It's a waste of space to just put a lot of plastic and air inside the body to "emulate" a battery

Welcome to 2009! :-) AA's have changed a lot, and they will improve further during the years to come.

I have a few "NP400 Replacement" batteries and some went dead pretty soon. So, I am not unhappy to replace those
Do you have any advise on brand/source for such batteries which have a decent quality? Besides the overprized original, I mean ...
B&H used to have "...Konica Minolta NP-400 Lithium-Ion Battery (7.4v 1500mAh) for DiMAGE A1, A2 & Maxxum 5D, 7D Digital Cameras..." for USD $10 apiece... that is an original NP-400, why do you need a replacement for it in this case ?

I am dissapointed

I have hoped that new battery will be compatible with D-LI50, just higher capacity.

Now they are forcing K-7 owners to buy new spare batteries

AA's in the grip? The size, the build quality, weather-sealed kit lens and now this? The K-7 is really turning out to be the ultimate backpacker's SLR!
Backpackers camera with battery grip? You must be joking

Panasonic, I guess, made its batteries w/ a chip to prevent people, for some at least, from buying a 3rd parties spares... isn't it the situation with G1 ?

Actually they don't run out.

If they do, yes, you have to remove the grip (not that much of a bother) if you want to change both. Or you can change just the one in the grip.

Thanks, y'all. That's kind of annoying, but oh well. Probably won't get the grip anyway so no big deal, but I'd be annoyed if I did and had to take it off every time I wanted to cycle out the in-body battery.

I'm actually dumbfound that people would even consider AA batteries to be an option in this case. I admit, I am not an expert when it comes to battery technology but I cannot fathom why AA batteries would be a preferred choice over a dedicated lithium ion battery. The experiences I have had with AA batteries are only negative. I remember AA batteries best from their ability to melt into my electronic appliances.


I would say we would see no real difference in this sort of performance. This is kind of how my AA powered point-and-shoot behaved. And how my DSLR behaves.
Lets say you going up the wilderness of the Amazon and have been traveling several days without electricity. Suddenly, your power is out and you spot a gift shop that MIGHT HAPPEN TO HAVE AA BATTERIES SO YOU CAN KEEP ON SHOOTING MAYBE? They provide the option because AA are so much more common and available than sockets, especially in China and Japan where the socket isn't even the same.

How many gift shops are there in the wilderness of the Amazon?

Would you travel to a foreign country without your battery charger and appropriate power socket adapters? By accident maybe, but then that would be your fault

AAs will always have the appeal of better availability, but really there are very few places in the world practically speaking where you'd be in real danger of running out of juice if you had, say, 4 Li-Ion batteries.

I think with shooting video, being able to put AA's in your battery grip would be a real potential advantage, especially if you're already carrying them for other stuff. (Or vice-versa: back in film days I'd often swap drive batteries out if I ran down the flash ones. ) And, the fact is, sometimes, plans go awry. It's a good option to have right there.

And, really, popping the grip off on a K20d is no big deal when it's time to recharge, ...without the vulnerable and bulky stick on there, actually it's more viable to keep it off if it's in the way or you don't want to carry it, but I can't see someone backpacking and complaining about a grip on a camera that small if they want to be doing some serious shooting out there.

I bought Uniross replacement and have been very happy with it.
Yes, all my additional ones are Uniross and they seem to match the performance of the originals. Got mine from Amazon for around 15 each
