I checked the K-r manual and it is actually rated for longer recording AND playback time using Nimh AA batteries over the brick. Brick takes more shots though. Both have their pluses and their minuses.
K-5 never took AA batteries outside of the grip. Hope they keep offering that ability in the DBG6 (or whatever the next battery grip is labeled).
In camera charging of the brick would be nice if the same cable would also function for downloading images too simultaneously.
That is more than twice the weight. Carrying a spare li-ion brick isn't too much of an issue, weight wise. AAs are more troublesome.
Mh... that's odd. Maybe Li-Ion collapses faster? But is able to recover? Or is it the other way round?
Yes, I think that's what they should do. Use the same port for transfering photos. And for crying out loud, use a standard cable that most people already have with them all the time (micro USB). You can charge your phone, transfer files from and to your phone, use it for battery packs, charge the camera, tablets, ...
The battery grip should of course always have space for AA, I agree.
My mother went to holiday with her small Canon superzoom that takes AAs. She had to carry 2 sets of batteries, and a rather bulky (though light) BC-700 charger (IMHO the best budget charger there is, comes from different brands, but it's great, charges all cells individually, treats them well, can repair them, ...). Then we had to find out that the batteries are in a bad shape, even though being of the eneloop variety and just a couple of years old. She ended up buying Alkaline AAs (occasionally, she couldn't always find them and tends to be a bit stingy too), which don't last nearly as long. So that's an advantage, but then again my K-5 Li-Ion battery is in much better shape, despite being about as old as her camera. She wouldn't have ran into that problem with Li-Ion in the first place. Which reminds me... with non rechargeable AAs my *istDS barely ran. Duracell, Energizer, ... 150 shots and it would be dead. The NiMH would be more around 1000 shots. On one trip that turned into a big issue, because I forgot my AA charger at home, and I couldn't always find non rechargeable batteries. Of course if I had forgotten my Li-Ion charger I would have been screwed even harder.
@Earl: I visited my mother, who lives on the (halfway) other side of the Earth. Forgot my charger there. Getting a replacement charger (that is way more awesome) wasn't too expensive though, cheaper than my BC-700.
Anyway, it's nice if they give the AA option, but IMHO I think it is overrated, and giving it USB charging capabilities with a common cable would be, IMHO, a much bigger advantage.
