Did you notice the disappearance of AA battery option in KS1, KS2...

The ability to use AA battery is an "Pentax only" feature - always there for entry and mid level Pentax camera, and in the external hand grip of flagship camera.

It is a really good feature, and one of the feature that attracted me to look at Pentax camera and eventually got me into Pentax (K200D).
The design of an 'adapter' in K-30 is brilliant, and I thought this design will stay...

But this feature is now disappeared in KS1, KS2....

Please keep this feature! It is one of Pentax unique selling point!

I agree, it is indeed a nice option. I would think the reason for not including the possibility for AA batteries in the new bodies simply is to keep the size down. Size seems to be a key factor for the K-2 line (or at least for the two released so far), and the adapter does take up a bit more space than the D-Li109 alone.

Will Ricoh release another body with room for the adapter? I don't know, but I wouldn't be surprised, seeing the rate they keep rolling out new models these days...

No surprise on the K-S1 given the size constraints. Moving the card slot into the battery compartment pretty much ruled out room for the adapter.

The K-S2 was probably compromise - either leave out some features or support the adapter. There is a lot of empty space that could be used for other components.

And maybe based on sales of the adapter it wasn't that popular of an option.

For me, the AA adapter was one of killer features which convinced me to buy K-30.
It's really sad they've decided not to support it in the newer mid-range cameras.

The original adapter is ridiculously expensive for a small piece of plastic. There are cheap 3rd-party replacements with excellent quality.

Keep in mind the K-S2 is part of the K-S line. It is possible that a proper K-50 successor will follow, and it may have AA support. I'd say it was dropped to save space.

You know... I had a K-x, and lithium batteries were great. I have a K-30, and batteries do not last very long (I have to get a proper adapter... this cheap one from Amazon doesn't work). Alkaline (typical) AA batteries are effectively useless in a D-SLR. NiMH are decent, as long as you don't use flash or much video. I've heard Eneloops are the only thing worthwhile if you're not going pure lithium.

I would have been using eneloops if the K-S1 had the ability to use the adapter. But it doesn't and I doubt that it will make a scrap of difference in how I use my K-S1. For me the K-S1 is great and doesn't have all the bells & whistles that I don't want - unlike the K-S2 which does and is heavier. The K-S2 is no doubt fine for many people but I'm quite content that I don't have one.

I'm a new owner of the K50 and bought the adapter from Amazon for about $6 even before the camera got here. I use it with Eneloops, trading off with the furnished battery. The Eneloops seem to last just as long as the Pentax battery and they work flawlessly. I agree, nice feature.

eneloops are quite expensive though, not to mention heavy. Might as well get Li-Ions.

You don't have to buy eneloop btw. LSD is the magic word, chances are they are identical to eneloop, just cheaper. And even if not they will be similar.

Hasn't disappeared if it was never there for those cameras
Personally I never thought it was a sound idea. Cheaper, more convenient and less bulky to keep one or two extra D-LI109's

that is probably because the price is too high for an OEM one. If it is not popular, there will not have 3rd party producing it....

I use only AA eneloops with my k30. After getting AA adapter not used that original batt even once. Hope pentax will continue again AA compatible batt bodies in the future. I have my eneloops no need to play with other batts and chargers.

It's really good with my K-30 knowing that out and about a service station or convenience store can provide AAs to get some more shots, but in practice, with the K-S1 I carry a couple of spare Li-109s anyway.

Aside from the remote/rare possibility of being caught out with a flat battery and being close to a shop/service stn that actually has some decent AA's.. Can someone please give me some sound reasoning why having dual battery options (and one which requires a special holder as well) is even a good idea? I really don't see it. I mean rather than needing 1 extra Li-109 you need 4x AAs and an adapter!? Seems totally nutty to me

And to those who say they only use eneloops, well good choice for sure, but this means you didn't just buy them at a service stn because you ran out of Li-109 power, it means you brought them with you when you really only needed spare Li-109s. So this kind'a of cancels out the argument.
