If no AF assist lamp, then it's the new AF contract detect sensor. =)

Well, quickly looked over latest posts in Форумы Пента-клуба (Powered by Invision Power Board)

Again, Om81 has made some hints, con't guarrantee they are true:

- Om81 was joking when was talking about focussing screen, K-7 has standard matte focussing screen.
- Om81 was able to quickly try K-7, he says it is very good camera although there's something he didn't like about the body.
- Hints that K-7 will be able to shoot faster than 5fps (said that 5fps was the fastest shooting speed for Pentax camera until 20th of May) and it is sensor which is limiting shooting speed, not the shutter.
- Hint that there's some new anti-dust thingy in K-7.
- Battery grip for K-7 will have AF button.
- Om81 also was saying something about in camera HDR, but it is possible that he was talking about multiexposure which we already have in K10D and K20D.

Finally they were talking (joking?) about starting writing in "broken" Russian, so pentaxforums English speaking users won't be able to translate their forum with web translators Well, good for me, I speak Russian much better than English, no problems understanding their broken Russian at all
There is a patent describing a system where you make two or more exposure saves from the moment the first curtain starts to the moment the trailing curtain closes averaging to a final image. This is the same as multi expo but within a unique shot. HDR is increased a lot.

or the white small lamp from the K-7 would be a light sensor when taking videos. same as the light sensor from phone's.

Same function as in Sony's cybershot (Best Pic)

Yeah!
A contract detector!
That would be really new and useful!

It then will probably also have an Auto contract feature with manual limit setting?
Cool is also the new contract bracketing function.

Bang!

Hopefully when Pentax annouces the K-7, it would be like a Loud bang.

Same function maybe, but very different results. And sony does not have shutter curtains.

Hey! That gave me an idea for the "What's wrong with the camera" game!!

In fact, Pentax has implemented some kind of new high quality contrast AF system... BUT... to take full advantage of it, you need an updated set of lenses specially designed for it!!

Unfortunately, and given the limited ressources Pentax has, the first of these updated lens won't be available before Photokina 2010 and should then be released on a yearly basis (two lenses a year) until 2020...

How's that for a "slight downside" pentax's style?

... WAIT A MINUTE ...

Have I been the only one to notice this:

Om81 on penta-club.ru has a (new?) signature line, which reads:
I ? SAF0X-iiX
(the current one is SAFOX-VIII)


So, a first bit of information being leaked?
malfunctions built right into the name of the af system...great!

Cheers,

I've read somewhat this patent. Does it somehow gives better Dynamic Range by taking two exposed shot then fused to one?

The only problem is that there is no more film to meter from....

surface reflectivity of the sensor would render "off the sensor" metering very difficult if not impossible I am afraid.
Actually, this is probably trivial with a digital sensor. You just have be able to monitor the information collected by the sensor as it is collecting, and close the shutter when the average is 18% grey (+/- any exposure adjustment). It's a programming or hardware monitoring issue if you can monitor the main sensor in real time.

If you can't monitor the main sensor in real time, then a simple external sensor could do the same thing. Maybe that's what the thing by the grip is?

High DR is a Samsung Patent

And it would eliminate the need for bracketing when properly implemented.

The idea is simple, you add a counter to each sensor pixel bucket.
Let's assume a bucket maps the amount of photons catched in the range 0-4095 (12 bits). On a normal sensor you blow the highlights when the bucket is full (4095). The Samsung patent however empties the bucket, when it is full and increments the counter. At the end of the exposure you read both the value of each bucket (0-4095) and the number of overflows (eg 0 - 15, if 4 bits are used).

With this sample implementation you will get 4 extra stops of dynamic range and real 16 bit raw files...
