K10D to use proprietary lithium battery pack?

Well, Sigma Germany is just around the corner (ok 30min drive)

reverse engineering other manufacturers' lens mounts. It's a
trade-off I could imagine to accept, if the camera delivers
elsewhere.

It's a funny old mount, the SA. It's nearly a K-mount physically but with the wrong registration, and the electronics are pure reverse-engineered Canon - which is why Sigma offer a service to interchange Canon and Sigma mounts on their lenses for a nominal fee. Someone has even sold Canon-L glass remounted to Sigma SA using mounts bought as spares from Sigma. Apparently the lens electronics are pin-for-pin compatible.

If the SD11 (if it appears) is as big an improvement over the SD10 as the SD10 was over the SD9 that I had it will be an interesting camera.

That I didn't!

I agree, but to be honest, I doubt it will materialise

"Babbling" you mean

But it is a nice way of letting the thoughts walk around: elaborated blabbering... Just see what it came out of it here!

One can't say things about cameras that even don't exist yet, but I would prefer a Fuji S4 over a Sigma SD11 any day. Just as I prefer Nikon lenses to Sigma lenses. In reality that is an opinion based on second hand information only. Should there really appear an SD11 I'll be happy to have a look at it.

Absolutely!

A bigger sensor? Just to show how single minded I am - I'm still hoping for a somewhat bigger sensor in the next Pentax.

Yes, they keep charge as long as non-rechargeable Lithium
batteries. That's why I'm happy with this change. One more minor
advantage of Li-Ion accus is that they are far easier to exchange
quickly - important thing if you do for instance wedding photos...

The available RCR-V3 batteries keep their charge. I guess changing the plastic wrapped around them will make no difference.

I get about 800-1000 on mine as well - but I'm liking the price of
yours a lot!!!

Of course..

Interesting to see the differenve in mAh... it once again shows that there are no standards. And thatis also the reasons why so few use these very good batteries - the lack of standards makes the customer uncertain about which battery to buy.

Oh my, get a good&small AA charger, they don't cost much.

Here's a good one:
http://www.shutterbug.net/news/121605uniross/index.html

It folds up very small, comes with US, European & UK plugs and happily charges four AA batteries

I like mine very much

Heya!

parallaxproblem said:

Yes, it's a good one

Mine is a larger, but faster and (more importantly for me) has an adapter for the car (cigarette lighter socket thingy).

Most important is a charger that has individual cell supervision. Otherwise, if one cell loses a bit of punch, a charger that only looks at the complete pack will make the cell worse and worse until the whole pack is almost useless.

Thankfully, these chargers aren't as common as they used to be. But I'd become suspicious if there's a very cheap charger deal...

Switch to a brand using AA batteries?

Click to expand...

Not many around. The reason is that AA and TTL and size are/were
the main reasons for me to decide upon Pentax. Sizewise, other
manufacturers have caught up, and if Pentax drops TTL and AA, I
might as well switch to a brand that delivers in other regards.

JensR said:

Is it rude to ask in what direction your mind goes (thinking of
jumping ship)?

Click to expand...

I'm secretly hoping for Fuji showing a small S4semipro and Sigma
showing an SD11. But I don't have any preference because basically
every camera has or is likely to have flaws I don't like. Maybe in
the end, Pentax still comes out on top, when balancing + and -, but
I am very open regarding brand choice.

Err, wouldn't you be better off size wise just getting the K10D and the grip for using AAs (if it only takes AAs in the grip)?

Rest assured I will look at all sensible options.

Personally, I dont care if its powered by solar cells, as long as its long lasting and does the job well

Well that's what most of the Internet-sites say, doesn't seem too bad for a rechargeable. Better than NiMH, possibly worse than those new AA Eneloops. And of course worse than non-rechargeables like Lithium CR-V3 and especially Lithium AA that has virtually no selfdischarge.

Ideally it should provide the user with the option of either/or. It has been done before with Samsung and Ricoh offering it recently. Also some manufacturers have offered grips that do either AA or propertiories...

Pete Fang said:
According to this PDML post, the K10D could use a lithium battery
pack called the D-LI50. The same post also states that the K10D's
battery grip will be called the D-BG2.

http://www.mail-archive.com/pentax-discuss%40pdml.net/msg339394.html

If this were true, it could mean a number of things:

K10D won't be compatible with the *ist D battery grip, D-BG1. But

this makes sense if the body of the K10D is weather sealed.

K10D body could be no longer compatible with AA batteries,

although AA support could be featured via the battery grip.

I certanly hope so; expenxive proprietary batteries can be a bit of a pain if you're shooting for a long time, and have to buy extra sets. If they're smarrt, they'll allow for AA's and also allow for CF cards, perhaps with a dual-format slot.

More user flexibility and more user choice is a good thing!!!

There's no reason to NOT being compatible with BOTH a proprietary lithion pack and AA batteries. Take out the battery pack, install the AA batteries, remove the AA batteries and install the battery pack. With a clever design, both can be used. BUT, on AA's the camera is likely to run slower, not showing it's best in performance. So, it won't be a top performer with AA's, but I'm sure it will work. It can take images.

Take care

You are right. Why should PENTAX register a patent like the following?

It looks like this patent could very well be for the K10D..

The drawings show they have placed the 4 AA's now symmetrical, that would make it easier to fit a Li-ION block.

My bro says he once had a Pentax SLR that was made for a proprietary
battery. A AA battery holder holder was also available for it.

He refused to get it as it was not cheap, and he rigged his own
external battery pack for it.
